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). If i run the python script from the home directory ls This is a quick modification I made. Ive got no idea why the device PCB suggests the address is 0x78 when it is clearly 0x3c. (sorry if this is a duplicate, but it didnt look like it posted before? Look for the standard pixel operator font and copy the font into the same directory as your stats script. I love tinkering with electronics, making, fixing, and building - I'm always looking for new projects and exciting DIY ideas.
disp.begin() 23 days ago Pascal. I'm sure it has something to do with me not understanding the '$NF==' stuff, any tips would be appreciated! Like a mounted USB disk? I use user pi for logon and the entry in crontab is exactly as described in the tutorial??? Youll then need to copy the filename of your font, along with the extension, to put into the script. You can also play around with the font size by editing the number after the font name, Ive used 16 here. This was working well while I used the default font.
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? File setup.py, line 4, in 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. Some of the product links on this page are affiliate links. As a noob to Raspberry Pis I am still learning about programming and how to use the Pi. I tried copying the line with a new string and using 'df -h /dev/sda1' which works in the terminal but here no new line shows up. 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). Replace the following lines in the # Write two lines of text section. 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. 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. It should be possible, but you would need a screen that allowed you to change the default I2C address.
disp.image(image) Ensure git is installed by running : Then clone the repository using the following command : Once that completes navigate to the librarys directory : This process will give you ability to include the library within your own Python scripts. Yes, I would expect that you should be getting at least 4-5% when idle. dtoverlay=i2c-gpio,i2c_gpio_sda=5,i2c_gpio_scl=6 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. /facepalm, of course it shows after I posted again.
Id be happy to add your remix download to the original cases and this post, with full credit to you. There is only 1 other 3.3V pin and that is pin 17. Did you enable I2C and instal python-smbus and i2c-tools? with archive_context(archive_filename): draw.rectangle((0,0,width,height), outline=0, fill=0) # Write two lines of text. I was wondering where I would be able to change the GPIO pins as I want to set my relais there (respectively the setup forsees so). This is far and away the most concise and well explained tutorial I have read about displaying your own images. Hope it is an easy fix, Im just not sure what to do. As with all my projects I started off by creating an SD card with the latest Raspbian image. But if i compare it to the RaspiOS Buster panel usage monoitor it should give you arround 4 7% in idle. It would be terrific for you folks to offer everyone a script/instruction to use this little beauty for a multi color Pi stats display!! sorry again! So i2c_gpio_sda=5 means GPIO5, physical pin 29. Resizing and converting takes extra processing time so in high performance applications you are better feeding the script images that have already been resized. But we want it to run all the time and run on startup, so theres one last thing to do. File monitor.py, line 26, in Is there a way to reverse actions and start over? Python is sensitive to the indentation of each line, so Ive youve modified these in any way, then the lines might not be functioning as expected. 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. My screen had four pins, two for power and two for the I2C interface. Running the script you can now see that the characters are gone and the temperature is being displayed alongside the CPU load: This is where I left the display in my original video, but it looks a lot better if you use a better font, which allows the text to fit into the width limit and uses the full height of the display, so lets look at that next. Adafruit use ppm as the library also supports their colour OLED modules. the screen worked immediately. The only thing I had to troubleshoot was I received two errors. git clone http://github.com/Adafruit/Adafruit_python_SSD1306.git return freetype(font) I then put the SD card into my Pi3 and it did detected the screen plus the examples straight away. Thanks so much for making this follow up tutorial because I was having a little bit of trouble using the original one you created. The cheaper ones have single colour pixels that are either white, yellow or blue. 
sudo apt update after doing some research I was able to fix this. File /home/pi/Adafruit_Python_SSD1306/examples/stats.py, line 71, in Great video and mod for your original case. use_setuptools() So you tried image.py example and wondered how you can create your own images? Share it with us! # Added by Gene 1 and 14 are 3.3V and Ground. . This is the default hex address for this type of device. See below. disp.display() You can see the text isnt that clear, there are a few weird characters on the display and the CPU temperature isnt displayed. Ive tweaked the code, fixed indentation erros and now it seems to be working! This is really great and I got it to work perfectly. Hello, Followed this and almost got it working only issue I am presented with is right at the end. 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. Dont proceed with trying to get the script to work if you dont get the correct response in this step, if your Pi isnt able to see the display thats connected to it then it wont be able to communicate with it to get anything displayed. Make the change and then save/quit using CTRL-X, Y then ENTER. Well start by hooking the display up to the Raspberry Pi. had no issue installing.Getting the data was done in another way. Run the bellow command on terminal: Scroll down, and just before the exit 0 line, enter the following: Did you make this project? 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. Everything went well according to the tutorial, except for the display programming. Delete your Crontab file and create a new one, or just replace the existing one. Once youve booted up your Pi, you should be on the Raspberry Pi OS desktop. I followed it to the letter and got the desired result when running the python script from the command line. Open up the examples folder in the Adafruit library which you were working on in the previous step and use the Thonny Python IDE to open up the stats script so that you can edit it. By default the image.py example will convert the image to 1-bit but it assumes the resolution is correct. The following lines will be added to show CPU temperature on OLED display module: Below code was modified accordingly to remove 'b' character from the OLED display. We hope to help everyone get the most out of their Pi by providing clear, simple articles on configuring, programming and operating it. I really enjoyed this project, making the case and getting the display functioning. 
Best regards, Yes you can change the script to display any metrics available via the shell scripts.
If you do too, grab a cup of coffee and settle in, I'm happy to have you here. I think the set of commands are out dated. Thanks So I made a remix of your case because I am more a fan of round edges. Some allow this by soldering two contacts together. I havent seen those packages come up previously, what operating system/version are you running? Crontab -e 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. Finally, you should see something similar to the following output on OLED display: You can easily make it so this program runs every time you boot your Raspberry Pi. So I would imagine you could pull data from pi-hole if you wanted to. 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 but still this program does not run at startup! You have entered an incorrect email address! I think you can get 2 x 8 channel multiplexers to 16 screens working. Unfortunately no easy solution is available as the Pi only has the temperature available in celsius. I am in same boat. I wanted to know how to display 2 Pages with different informations in first. This display is actually a 128 x 64 display, not the 128 x 32 display which is set by default. One question would I be able to display pi-hole stats? Those are fine but youll need to follow a different tutorial to use that style. **** At this point it the OLED should now show its display **** I checked everything! My OLEDdisplay module is a 0.96 I2C IIC SPI Serial 128X64 OLED LCD LED Display Module. I have a question regarding 3d printinhg the case (all the haps on the case have support filling which can be pushed out after printing. thanks for the great Case and your work with all those detailed tutorials. I receive a small commission based on purchases made via these links. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-medrectangle-4','ezslot_10',174,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-medrectangle-4-0')}; These displays dont have reverse polarity protection, so if you connect them incorrectly (even just once) then its quite likely that theyll be damaged and will no longer work, even if you correct the wiring afterward. 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. Ive just Googled it and understand now. cd Adafruit_python_SSD1306/ If your screen allows you to change to an alternative address you should be able to run two on the same pins. After getting your octopi monitor easy board kit, I just had to try the Raspberry pi desktop case with oled screen. There are plenty of Ground pins. sudo i2cdetect -y 1 I bought a Waveshare 1.5 inch rgb oled for my pi. And of course I would give you a proper credit and will link this page in the post. If I add the script in the crontab and reboot, the display flashes up and goes blank. ), and RPi.GPIO, but I couldnt get them all installed at this time, so I gave up for now. Ill get this step added to the guide as well. Works great! Thank you! 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. 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. I could not try it out until now, but I definitly will. You can edit the example scripts on the command line using : same for IP? time.sleep(2), #Clear Display File /home/pi/Adafruit_Python_SSD1306/examples/stats.py, line 103, in Copyright 2022 - All Rights Reserved - Matt Hawkins. Slowly getting more familiar with my raspberry pi as its my first encounter but not TOO familiar yet. Unofficial site devoted to the Raspberry Pi credit card sized computer offering tutorials, guides, resources,scripts and downloads. I resolved it by changing to the directory of the script before running it in cron. but I get RuntimeError: Could not determine platform.. But when I run the stats.py, I get the variables preceded by a b and followed by \n. Now we are ready to test some examples scripts. Greetings, File /home/pi/.local/lib/python3.7/site-packages/PIL/ImageFont.py, line 210, in __init__ In this tutorial Ill explain how I setup my0.96 OLED display module using the Pis I2C interface. Rav. Before we do this we need to enable I2C communication on the Pi as this is how it communicates with the display. They are available in various sizes but common sizes include 12832 and 12864 pixels. I use your script from Github, but it mostly shows 0.00% and from time to time you can see 1.00%. Thanks for also the small additions and changes to layout and change the font! 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! 
self._RealGetContents() Anybody aware of the cause? I tried to get it work for hours with the official tutorial of the screen, but it was far to complicated and didnt work. OSError: cannot open resource. Any ideas ?? sudo python -m pip install upgrade pip setuptools wheel How can I solve this?
