Make sure that your Pi is off and the power is disconnected before plugging or unplugging jumpers from the GPIO pins. Great Job. Description:This mini OLED is designed for Raspberry Pi modules. There is very little info regarding these little screens beyond setting them up. We hope to help everyone get the most out of their Pi by providing clear, simple articles on configuring, programming and operating it. Raspberry Pi is a trademark of the Raspberry Pi Foundation. draw.text((x, top+8), str(CPU), font=font, fill=255) zipfile.BadZipfile: File is not a zip file. The PiOLED comes with a monochrome 128x64 OLED, with white pixels. I have never tried to do so, but you can set the script to display any metrics that are made available by other applications. Thank you for sharing this great information! # Added by Gene If i run the python script from the home directory Using an I2C OLED Display Module with the Raspberry Pi, CrowPi L Raspberry Pi Laptop and Learning Platform, Enable the I2C Interface on the Raspberry Pi, https://github.com/adafruit/Adafruit_Python_SSD1306/issues/22, Analogue Sensors On The Raspberry Pi Using An MCP3008, Copy to your Pi in the same location as your Python script, Update the Python script to use your new file. Can someone guide me to change lib file, I get as far as _build_egg(egg, archive, to_dir) I have a problem while installing the python library. When i execute the command, Extracting in /tmp/tmpoaIjab draw.text((x, top), IP: + str(IP), font=font, fill=255) I could not try it out until now, but I definitly will. It works fine. You can do this within the raspi-config tool on the command line by running : For additional details on this step please see my how toEnable the I2C Interface on the Raspberry Pi post. How would I make an image that makes use of both of those colours? Delete your Crontab file and create a new one, or just replace the existing one. Is there something i missed with the set up for the zero which is stopping this? Adafruit use ppm as the library also supports their colour OLED modules. This screen is made of 128x64 individual white OLED pixels and because the display makes its own light, no backlight is required. I have one OLED running stats.py fine, and would like to add a second OLED with another script running, like shapes.py or animate.py. Did you manage to move from this step? If youre installing the display into your case before connecting it then its a good idea to write down which colour is connected to which pin so that you dont forget. Resizing and converting takes extra processing time so in high performance applications you are better feeding the script images that have already been resized. Hello! Have you built it into your own case? Its probably my fault because I opted to use a direct path to the stats.py file in the example folder rather than placing it and the font file on my desktop. time.sleep(2). and library does not install. HEy very straight forward and easy to do. Hello, I managed to get my OLED screen to work on my Pi3 but cant get it to work on the Pi zero w. The script is one of the example scripts provided in the Adafruit Python SSD1306 library, with some tweaks. Make sure that the python version you choose here matches the version you are going to run the actual script in. Hi Jennitty, ), and RPi.GPIO, but I couldnt get them all installed at this time, so I gave up for now. sudo pip3 install upgrade Adafruit_BBIO Hi, my name is Michael and I started this blog in 2016 to share my DIY journey with you. So lets now look at changing the font. Ive just resolved it by running pip3 install Adafruit-BBIO just a guess. Thanks for the update Pascal, happy to hear youve managed to get it working correctly. disp.display() This is a great tutorial. ), After following this guide, I got to running python3 stats.py Add the following two lines to the script at the end of the # Shell scripts for system monitoring from here section. Ive just Googled it and understand now. Thanks for explaining that. The OLED displays pins are labeled on the front, which seems to confuse a lot of people, especially when theyve installed the display into a case or housing and the front area above the screen is no longer visible. The colours on the cable dont matter, theyre just there to help you keep track of which wire goes to which terminal. The I2C interface is disabled by default so you need to enable it. Regarding my last post, about a problem connecting with i2c to the display I found that one of my breadboard wires was not conducting. Loved this whole project. There are plenty of Ground pins. Did some googling around but could not get this to resolve Any ideas? My screen had four pins, two for power and two for the I2C interface. In this tutorial Ill explain how I setup my0.96 OLED display module using the Pis I2C interface. Quick question, Is there a way to display temp in Farenheit and not celsius? >>> %Run stats.py If you want to load an image or photo then load it into your graphics application and perform the following steps : The Adafruit example image is a ppm file because it is colour although it is converted to monochrome at the point it is displayed on the screen. If your table is returned blank then youve either got a wiring issue or I2C communication isnt turned on. The cheaper ones have single colour pixels that are either white, yellow or blue. The example code allows you to draw images, text, whatever you like, using the Python imaging library. sudo apt-get install python3-dev python3-rpi.gpio I immediately got started using your tutorial and I have to say that everything worked great with the exception for the final step. ImportError: No module named PIL. Miniature OLED display modules are a great way to add a small screen to your Raspberry Pi projects. Add the following line to the end of the file to run the script: You might need to change the directory to suit the directory that youve got your script saved into. false code: cmd = hostname -I |cut -f 2 -d , right code: cmd = hostname -I |cut -f 2 -d ='. File /usr/lib/python2.7/zipfile.py, line 813, in _RealGetContents I ran through this post myself when I was rebuilding my Pi-Hole system. I created this the get something like a miniature version of my Desktop PC Case (Aerocool DS Dube), which I really love. However if i run python3 stats.py directly from the examples folder it works.. However Ive never tried this myself. Thanks for also the small additions and changes to layout and change the font! If you do too, grab a cup of coffee and settle in, I'm happy to have you here. Are the four module connections correct? sudo apt-get install python3 This is the default hex address for this type of device. Plug your ribbon cable into these pins and then make a note of which colour youve got connected to which of the four pins. Windows likely doesnt have the same packages/libraries that Rapsberry Pi OS does so I think itll be a bit of a challenge to get it to run. After I connect the i2c screen it seems to replace the temp sensor replaced with a set of DS18b20 unrelated serial numbers Any thoughts on whats going on would be greatly appreciated! Some of the product links on this page are affiliate links. Heres how I did it if anyone is wondering: Insert: new_temp = str(temp[0:2], utf-8) + +C Hopefully it works for you. The section in the script should now look like this : This step becomes essential if you want to start creating your own images to display on the screen. Alternatively, I did try it from the home screen as describe in your instructions and it still did not work. 0x3c is these 7 bits 111100 but once the R/W bit is included it becomes these 8 bits 1111000 which is 0x78. See if you can guess which ones were photos I downloaded to my Pi from Google Images! Id be happy to add your remix download to the original cases and this post, with full credit to you. Hi Ivan, you can get an I2C multiplexer to add 8 screens. Update: For those running Raspberry Pi OS Bullseye, please use my revised guide. at first following your step, everything worked totally fine! Next lets have a look at the python script and how to install it. ls Now we are ready to test some examples scripts. The price you pay is the same. One question would I be able to display pi-hole stats? Did you enable I2C and instal python-smbus and i2c-tools? FYI, I had this same issue. Its possible to do this installation on a headless Pi as well, its just easier to make the required layout changes to the script in the full version first. ls Is the screen compatible with the Raspberry Pi Zero? Not sure if youve tried but Im adding Windows 11 with my son onto his RPI 4 8Gig with your Ice case. This was working well while I used the default font. Hopefully they will resolve it soon. It should be possible, but you would need a screen that allowed you to change the default I2C address. disp.begin() Try either relocating both the script and font into the default directory /home/pi/ or rather use the default font. The following steps are done on the Raspberry Pi OS desktop and edits to the script are made in Thonny Python IDE (which comes pre-installed). font, size, index, encoding, layout_engine=layout_engine Were not so much interested in the library as we are in the stats example script, so were going to use it anyway.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-large-leaderboard-2','ezslot_14',176,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-large-leaderboard-2-0')}; Download the script by typing in the following commands: Next, navigate to your librarys directory: Then run the setup script to install the library. If you now run the script youll see that the text is a bit taller and is in your new font, but its still bunched up at the top of the display. Those are fine but youll need to follow a different tutorial to use that style. But if i compare it to the RaspiOS Buster panel usage monoitor it should give you arround 4 7% in idle. In crontab after I try to exit it says File name to write: /tmp/crontab.LfxgzD/crontab and it gives me a bunch of options but you never said which one to do. This is really great and I got it to work perfectly. Wired and Wifi? Matt- The reason why the PCB said 0x78 and youre reading 0x3C from i2c-tools is: I2c-tools shifts the entire address to the left by 1 (adding the last bit for R/W). Thanks for detailed instructions! I havent got one of those blue/yellow boards but I suspect the colour is fixed in particular zones of the screen. Before detecting the OLED, when I run the following in cmd: It returns a serial number (28-xxxx). Thanks Matt. Copy the OLED stats display script and the font into your home directory. If I add the script in the crontab and reboot, the display flashes up and goes blank. return _do_download(version, download_base, to_dir, download_delay) Then if i follow the last steps and have the script run on boot, will it auto turn on? I think you have to install more libraries if using Raspbian Lite. If you dont have a colour screen you can switch to pbm or png. sudo nano shapes.py Heres a video guide to connect and program the OLED stats display, read on for the full written guide and script modifications. I get the same error. It just means that they have developed a better or more recent set of libraries. how do you chang the screen size as you stated from 12832 to 12864 i cant figure how to do it please help. If you get a table full of characters then youve probably made a wiring mistake as this happens if SDA is shorted to ground. Again, you can use any of the 3.3V or 5V power pins as this display can run on both 3.3V and 5V. Thank you again for a great tutorial and for the amazing case! Download the font PixelOperator.ttf from https://www.dafont.com/pixel-operator.font and then unzip the contents of the download. I navigate to the Examples directory as per your command but when I run python3 stats.py I keep getting the error: Please see theChange Raspberry Pi I2C Bus Speed post . from PIL import Image Hello, Followed this and almost got it working only issue I am presented with is right at the end. You can either do this through the preferences menu or by typing this command into a new terminal window: Select interfacing options, then I2C and then select Yes and then reboot the Pi by typing in the following command:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'the_diy_life_com-banner-1','ezslot_12',175,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-banner-1-0')}; Once your Pi has rebooted, you need to check that the following 3 libraries have been installed. Youre seeing this ad based on the products relevance to your search query. Awesome! One note though, pip3 isnt always installed, so I suggest adding the sudo apt install python3-pip command before entering the sudo pip3 command. I then put the SD card into my Pi3 and it did detected the screen plus the examples straight away. Everything went well according to the tutorial, except for the display programming. Thanks Michael. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-box-4','ezslot_8',170,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-box-4-0')};Next, you need to plug the other ends of the jumpers into your Raspberry Pis GPIO pins. Nonetheless, I cannot get the script to auto run upon reboot. Rav. Slowly getting more familiar with my raspberry pi as its my first encounter but not TOO familiar yet. I am noob here. Im new to the world of R-PI and was extremely excited when cases arrived today. This would set up a new interface at /dev/i2c-3. Great tutorial on building and configuring the OLED. File /home/pi/Adafruit_Python_SSD1306/ez_setup.py, line 88, in archive_context Would the script have to change at all? sudo apt-get install python-smbus Comment out the line which loads the default font: Uncomment the line which loads the replacement font and paste your filename into it, keeping the inverted commas on either side. os.chdir(/home/pi/Adafruit_Python_SSD1306/examples), I had to add the following to my stats.py script as I was not running the script from the root of my home folder There is a note on the Github page to say that this is a depreciated library, but that doesnt mean that you cant use it or that it will no longer work. Press Esc to cancel. Ive got an OLED display that displays in blue/yellow its also based on the 1306.

Follow instructions but unfortunately my OLED is sh1106. This display is actually a 128 x 64 display, not the 128 x 32 display which is set by default. However when I inserted it into the crontab for automatic startup, it shows a brief moment the correct settings on the display and then all of the sudden switches to a two line display. If it is all working correctly then you should have a working stats display which starts up automatically each time your Pi boots up. Ive found this happens from time to time on my Pis as well. I found the code to correct the issue on my display. Thanks for the tutorial. Traceback (most recent call last): I needed to adjust my crontab to look like this, @reboot cd /home/me/scripts && python3 stats.py &, after doing this modification it started to work again. The display can work with 30 FPS update rates so you can do animations or simple video.Comes completely pre-assembled and tested so you don't need to do anything but plug it in and install our Python code! Your recently viewed items and featured recommendations, Select the department you want to search in. These are most commonly GND, VCC, SCL, and SDA. after doing some research I was able to fix this. Copy these two portions of the script below and paste them into your script on your Pi. dtoverlay=i2c-gpio,i2c_gpio_sda=5,i2c_gpio_scl=6 I am in same boat. I resolved it by changing to the directory of the script before running it in cron. I had to install python3-dev before the setup script ran ok. *sudo apt-get install python3-dev*. If youve got an original Model B Rev 1 Pi then type the following command instead : In order to display text, shapes and images you can use the Adafruit Python library. Next navigate to the examples directory in the Adafruit directory: You should then see your Pis stats shown on the display. I plug the VCC jumper (mine is blue) into Pin 1, which is a 3.3V power pin. So the display stays black after a reboot until I run the python3 stats.py manually. I2C allows multiple devices on the same bus as long as you can give each device a unique ID. The display just runs on a simple Python script, so you can quite easily add additional information or remove unwanted information from what is displayed. use_setuptools() Is it possible to add the name of the server alone with the status to display? File monitor.py, line 26, in disp.image(image) File /home/pi/.local/lib/python3.7/site-packages/PIL/ImageFont.py, line 210, in __init__ Do the scripts default to run on y 1 / 0x3c, and its just a case of manually editing the script to look for the new device? I cant see where these added characters are coming from. draw.text((x, top+25), str(Disk), font=font, fill=255), # Display image. Thanks nevertheless for the fantastic tutorial .. Look for the standard pixel operator font and copy the font into the same directory as your stats script. ive the exact same problem but with an 12864 and i cant see the solution, Just found the solution after commenting -.-, https://stackoverflow.com/questions/37016946/remove-b-character-do-in-front-of-a-string-literal-in-python-3, you need to decode the string you want to display as utf-8. Then again, I read something about a BUS and that I could control different interfaces with sam pins ughhh. File setup.py, line 4, in return FreeTypeFont(font, size, index, encoding, layout_engine) I also checked the syslog and it says that the cronjob was runned but still a black display. Did you start with the latest version of Raspbian? Thank you very much for this tutorial. The only problem I have is that the IP address doesnt show the IP, just a set of numbers with a letter before the end. before the line : draw.text((x, top+18), str(CPU,utf-8) + + str(temp,utf-8) , font=font, fill=255), And change the line: draw.text((x, top+18), str(CPU,utf-8) + + str(temp,utf-8) , font=font, fill=255), to: draw.text((x, top+18), str(CPU,utf-8) + + new_temp , font=font, fill=255). First, lets change the display size so that were using all of the displays pixels so that the text is a bit clearer. Then I made sure this was up-to-date by running the following commands : This step may take a few minutes if there are lots of packages to update but it usually saves some frustration in the future. We can play around with the spacing, but this font is just not great for this stats layout. Edit the example python script using a text editor and make the change as described in the Screen Size Adjustment section. The following libraries may already be installed but run these commands anyway to make sure : If you are using Python 2 then use these commands instead : I would recommend using Python 3 unless you have a really good reason for using Python 2. draw.text((x, top), IP: + str(IP), font=font, fill=255) Load an image, resize and convert to 1-bit : Which technique you use is up to you. ** You can connect the Gnd pin to either Pin 6, 9, 14 , 20, 25, 30, 34 or 39 as they all provide Ground. git clone http://github.com/Adafruit/Adafruit_python_SSD1306.git git clone https://github.com/adafruit/Adafruit_Python_SSD1306.git all as one string, but did run them separate after since I got an error. Is it possible to have the Disk line Scroll and show each after another or switch between on and another? cd Adafruit_python_SSD1306/ I use this script on my Raspberry Pi Desktop Case and a lot of people have asked me for some more in-depth setup and programming instructions to get it running. File /home/pi/Adafruit_Python_SSD1306/ez_setup.py, line 108, in _do_download It also means your Python script doesnt need to convert them. and it just returns No module named pip. Thank you! It reduces the power required to run the OLED and that is why the display has such high contrast.We recommend using the adafruit Python library for the SSD1306 chipset. The library can handle both just make sure you use the correct filename and extension in your scripts. Yes you can change the script to display any metrics available via the shell scripts. So the last thing we need to do is adjust the layout.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-leader-3','ezslot_17',179,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-leader-3-0')}; Adjusting the layout is a bit of a guessing game until you get it looking the way youd like it to, or just copy the numbers Ive used: When youre done, you should now have a clear OLED stats display running on your Pi. Hi Alexander, I prefer creating pbm files as they are black and white and much smaller files. sorry again! Hi Matt, Ive got a 12832 screen from PiHut, and Ive been able to install and run as you suggest above. sudo apt-get install libopenjp2-7-dev but I get RuntimeError: Could not determine platform.. In your case, I would think that this crontab line should work: @reboot cd /home/pi/Adafruit_Python_SSD1306/examples; python3 /home/pi/Adafruit_Python_SSD1306/examples/stats.py &, Thank you very much for this instruction and fun little project. I leave this here just in case someone else experiencing the same problem , Thanks for your work again. . The Pis GPIO pinout diagram can be found quite easily online and is available on the official Raspberry Pi website. Check all of your connections again and youre then ready to power your Pi up and get started with programming the display. You have entered an incorrect email address! The OLED uses I2C pins so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. please help! I followed it to the letter and got the desired result when running the python script from the command line. The weird part about this is that when I click Run to check the script, sometimes the screen goes bananas, but after a reboot it works fine, haha! os.chdir(/home/pi/Adafruit_Python_SSD1306/examples). Comment out the line near the top which sets the display size to 128 x 32: And then uncomment the line which sets the display size to 128 x 64:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'the_diy_life_com-large-mobile-banner-2','ezslot_15',178,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-large-mobile-banner-2-0')}; If you run the script youll now see that the text is much clearer, but it all bunched up in the top half.
