controlling the full-color led

[Antony]

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!

@Antony Check to docs here:

https://onion.io/omega2-pro-get-started/#fullcolorled

You just need to write the require codes to the device file, this is very easy to do thanks to the great work by @luz on the ledchain system.

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!

@Antony The 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!
