Description

Pinout for Matrix LED on T-Echo is wrong(incomplete)

By reviewing the vendors scematic [2021/6/23] ( LED color Labeling is wrong but LED and other Port Pin Label should be fine) and Datasheet for RGB Matrix LED FM-B2020RGBA-HG and checking code with real behaviour on my device I found the correct Port Pinning for the LED should be.

RED P1.03 (32 + 3)
GREEN P1.01 (32 + 1)
BLUE P0.14 (0 + 14)

I made a code proposal on Pull Request #5326

Relevant log output

No response

From the pull request: "Your assertions are correct. Unfortunately, changing to new (correct) LED scheme broke the previous iterations of T-Echos. :-/"

So we may need to look at a new variant or some extra logic to handle the different generations of T-Echo.

Thanks for the feedback.

Hopefully there will be a solution in the future to get full functionality for the Matrix LED.
Please dont hasitate to contact me if you need any feedback regarding the 11/2024 T-Echo hardware I own.
