7inch How to modify code...

[SONJAEHYUN23]

Thank you always for your kind reply. Everything is sort of putting together the puzzle,
My current situation is that I'm going to use an esp32s3 7-inch board, and I'm going to make an optocoupler board and connect it to the Musikom le Switzer midi out terminal and esp32 7-inch board uart2 port. The power supply will be connected to the c-type uart port after removing the r115, and I'm going to connect the c-type and esp32 board. I confirmed that I should use 43devonly in this code process.. I don't know how to modify the code.. I'm not sure what files to download from the TexOne Controller project you uploaded that I'm studying in this part.. I'm not sure if I need to rebuild and download it after editing.. I really want to use the 7-inch board.. Please help me Do I need to modify the code to get the MIDI input to the uart2 port? Does it work if I just download 4.3B and upload it to the 7" board? If I need to modify the code (using 43devonly?) how do I modify it.. I really want to use your perfect project..

I did it by studying by myself, thank you. If you can help me further, please advise..

I will need a little more time. I will try to work something out to help you.

Thank you so much. I am serving as a soldier in Korea. I haven't tried it yet because the unit can't use cmd and terminals for security reasons. I will try it as soon as I go on vacation next week. Thank you.

I have created new documentation for the 7" (and 4.3 non-B version which is almost the same.):
https://github.com/Builty/TonexOneController/blob/main/HardwarePlatform_Waveshare7_4.3.md

I detailed that this platform cannot support directly wired footswitches, and has less amp skins as the memory is smaller. Everything else works as normal.

I will post an alpha release here soon, I am just completing the testing.

You are really my savior. Thank you so much. I can't describe it in words! I found out a few more things that I needed to use an optocoupler, so I made a simple pcb, but can I apply it and connect it to the adc?

R1 is resistance 220, R2 is resistance 10 kohm, C1 is optocoupler H11L1

I'm trying to connect two of the midi pin from the midi out terminal of the switch to the connector and then to the esp32 adc via the optocoupler board

Thank you for your hard work

Your Midi board should be fine. The "ADC" port on the 7" is just an input pin that can be set to read analog. I am not setting it for analog, but instead setting it to a UART input which is suitable for Midi.
The ADC port has 3.3v and ground also which can be used to power your optocoupler.

Here is a beta build below.
