@crispyoz said in controlling the full-color led:

language you use is not relevant, you are simply writing to a file, I suspect your code returning an error writing to the file, what response codes is your code reporting for the file open and write functions?

@crispyoz I am using python on the onion os, so its not telling me if I have errors in the code. Is there a way to debug easier? I know the code works when wiring a breadboard and led lights to the omega onion.

If I want the LED color on the Full-color LED turn blue on python do I just type: echo -en '\x00\xff\x00' > /dev/ledchain2 instead of something like gpio1.setvalue(1) as I would need to do for external LED lights?

Its also confusing because python also requires a "from" and "import" commands. But the document given by onion does not have this. It only has omega2-ctrl gpiomux set uart2 pwm23 to initialize the command in terminal.

Thanks again I very much appreciate your help!

Thank you @crispyoz !

I need python functions but https://onion.io/omega2-pro-get-started/#fullcolorled appears to not work with python, am I wrong? I tried with python and did not work.

Thanks again!

Hello,
I need help importing and viewing images on OLED Expansion board. I am using python and onion omega 2s+ pro module. I am not sure what functions to use. I looked at the onion help document and I am still lost.
Thank you!

Hello,
I see that with Power Dock 2, there is a node available for battery level. However, I do not see this node using a omega 2s+ pro. Is there a way to detect battery level using node-red on omega 2s+ pro?
Thank you!

Hello,
Is it possible to control the full-color led on an omega 2s+ pro using python? I want to create if else statements changing the color for different scenarios.
Thank you!

@crispyoz
Thanks for reaching out! Yeah, I mean to display the battery status onto the oled expansion.

And yes, I know how to write using the terminal and in Python I have been using
oledExp.driverInit() to initialize

oledExp.write() to write.

Can I use print() to display text on the oled expansion or is it just oledExp.write() function that I can use. I have not been able to get print() to work.

Thank you so much for your time, I appreciate it.
