ESP32_Lyra-T: Does someone want to port Marcel's work to this board with me?

[irgendwer92]

Hi,

first a bit of praise to Marcel: Mir gefällt richtig gut was du machst und wie du spielst! Ich such sowas schon seit Ewigkeiten!

I was wondering how much work it would be to get this library and the projects running on the ESP32 Lyra-T.
I thought it would be relatively similar to the audio kit and it was cheaper, so i bought two of them. But now i'm not so sure of that.

Here are the Docs: https://docs.espressif.com/projects/esp-adf/en/latest/design-guide/dev-boards/board-esp32-lyrat-v4.3.html

It's based on the WROVER-E, an ES8388, has a few touch buttons and another pinout i think.

I'm a bit intimidated to do that alone, a few nudges in the right direction would be nice.

It should be fairly easy to do. If it were me I would make a copy of the audio_kit_es8388 board description and name it esp32_lyra_t.h. From there make sure all of the assigned pins match your datasheet. Then you should be add that newly created board definition into ml_boards.h. From there you should just be able to #define ESP32_LYRA_T (or whatever you named it in ml_boards.h) in the config.h for the synth project you are trying to build.
Hope this helps. I would help more if I had a Lyra-t to test with and wasn’t so busy with my own projects. If you are still stuck (or just want to B.S. with other esp32 users) I can be easily reached on Telegram at ESP32/ESP8266/K210 Hackers. I know at least a few of our members have experience with several variations of the audio board, and a couple of us have been playing with Marcel’s amazing projects.

Hi @irgendwer92
Vielen vielen dank für das tolle Feedback!

@UncleGrumpy thx that is a good way to go. I've added a prototype which I had prepared some time ago: https://github.com/marcel-licence/ML_SynthTools/blob/main/src/boards/board_esp32_lyrat.h

I've updated the board selector as well to allow using #define BOARD_ESP32_LYRA_T to select this board.
Please feel free to tell me if something is missing.
The WROVER-E is a good choice. I think you should have PSRAM also available on this board. I used this on my DIY PCB some time ago.

Thank you both! I'll look into it when i have time again
