ESP32 SUSTAIN_PIN

[mcvall]

Hi Brandon. How to set up the SUSTAIN_PIN correctly in the sketch? I created a new sustain PWM output: "pinMode (SUSTAIN_PIN, OUTPUT);" connected LED to PIN 13, but it doesn't work. In the port monitor (ESP32), I see that a midi signal comes from the Control box (Pro micro), all notes except SUSTAIN. I plugged in the midi keyboard, all notes work just as well except SUSTAIN.
Thanks!

void setup ()
{
const int SUSTAIN_PIN = 13;
pinMode (SUSTAIN_PIN, OUTPUT);
pinMode (LED_BUILTIN, OUTPUT);
Serial.begin (38400);
initializeBluetooth ();

// create sustain PWM output. this can't be done by the Pro Micro because the shift registers are filled up
ledcSetup (0, 100, 8);
ledcAttachPin (SUSTAIN_PIN, 0);
}

did you manage to do the project? Can I contact you to clarify some doubts I have?

Hi. The project is still in progress. I make the solenoids myself, I also made the PCB. I hope to finish soon :) You can ask questions here.

Can you tell me more about your PCB?
