Hello everyone,

I have a working code that sends MIDI messages as a USB device to the computer. Now, I also want to send MIDI over the TX pin of the ESP32-S3 C1 Dev Board via a DIN connection.

My code works, and I can read the messages through a serial-to-USB cable when I connect the ESP32-S3 C1 to a 5V adapter. However, if I plug it into the USB port, it sends USB messages but not MIDI messages through the TX pin. The LED turns on...

I have a setup where I can read from USB MIDI as well as DIN MIDI In, and both work simultaneously. Am I doing something wrong?

Below is an example code that works with a 5V adapter but does not work when I connect the board via USB.

Code: Select all

void setup() {
  // Set MIDI baud rate:
  Serial.begin(31250);
}

void loop() {
  // play notes from F#-0 (0x1E) to F#-5 (0x5A):
  for (int note = 0x1E; note < 0x5A; note++) {
    //Note on channel 1 (0x90), some note value (note), middle velocity (0x45):
    noteOn(0x90, note, 0x45);
    delay(100);
    //Note on channel 1 (0x90), some note value (note), silent velocity (0x00):
    noteOn(0x90, note, 0x00);
    delay(100);
  }
}

// plays a MIDI note. Doesn't check to see that cmd is greater than 127, or that
// data values are less than 127:
void noteOn(int cmd, int pitch, int velocity) {
  Serial.write(cmd);
  Serial.write(pitch);
  Serial.write(velocity);
}

Arduino settings for the device attached.

Thank you.

Is there some reason you need to use Serial (UART0) and the rx/tx pins instead of Serial1 and whatever other pins you have available? It will be a lot easier to do so.
If you want to use Serial, you will need to disable the console output first (which should be `esp_log_level_set("*", ESP_LOG_NONE); Serial.end();` at the beginning of your setup) and then start it back up with your desired settings.

Thanks for the quick answer.

I have to use these two, because all others are used for GPIOs. If it is not possible, I will need to make a PCB change

. If I can solve it without hardware change, that would be perfect.

I updated my code as you suggested, but still same behaviour. Works when plugged to adapter, not if plugged to USB:

Code: Select all

#include "esp_log.h"  

void setup() {
  esp_log_level_set("*", ESP_LOG_NONE);
  Serial.end();
  Serial.begin(31250); // MIDI için baud hızı
}

void loop() {
  for (int note = 0x1E; note < 0x5A; note++) {
    noteOn(0x90, note, 0x45);
    delay(100);
    noteOn(0x90, note, 0x00);
    delay(100);
  }
}

void noteOn(int cmd, int pitch, int velocity) {
  Serial.write(cmd);
  Serial.write(pitch);
  Serial.write(velocity);
}

I still see the board in the COM list, though. Should this happen when I use the USB-OTG connector?

What version of arduino-esp32 are you running? You are missing the option for USB mode.
What you really want is to have HardwareSerial not attach anything to the USBSerial. If you look at the code, what you want is CDC boot turned off, and USB_MODE set to OTG (but not activated in code). These options have changed over time, so you really need to be on a fairly recent version for this to work.

I have arduino-ESP32 version 3.0.7 (looks like the most recent one).

I am also posting the compilation output.

Isn't the USBMode the 4th from the bottom on the image I've sent earlier?

What version of arduino-esp32 are you running? You are missing the option for USB mode.
What you really want is to have HardwareSerial not attach anything to the USBSerial. If you look at the code, what you want is CDC boot turned off, and USB_MODE set to OTG (but not activated in code). These options have changed over time, so you really need to be on a fairly recent version for this to work.

Hello again,

I built another setup on a breadboard. Can you maybe help me try the other alternative, if there is no change to do it using my way?

It's not exceptionally difficult, but it involves a permanent change to your hardware. You need to burn an efuse to stop boot logging on those pins. Once that is done, just call Serial0.end() at the very top of your code, the reinitialize it with the setting you want.

Thanks.

Done it.

Code: Select all

espefuse.py --chip auto burn_efuse UART_PRINT_CONTROL 3 --port COM4
espefuse.py v4.8.dev5
Connecting...
Detecting chip type... ESP32-S3

=== Run "burn_efuse" command ===
The efuses to burn:
  from BLOCK0
     - UART_PRINT_CONTROL

Burning efuses:

    - 'UART_PRINT_CONTROL' (Set the default UART boot message output mode) 0b00 -> 0b11


Check all blocks for burn...
idx, BLOCK_NAME,          Conclusion
[00] BLOCK0               is not empty
        (written ): 0x0000000000000100000000000000d1f50000000000000000
        (to write): 0x00000000000000c000000000000000000000000000000000
        (coding scheme = NONE)
.
This is an irreversible operation!
Type 'BURN' (all capitals) to continue.
BURN
BURN BLOCK0  - OK (all write block bits are set)
Reading updated efuses...
Checking efuses...
Successful

And updated the code:

Code: Select all

void setup() {
  // Set MIDI baud rate:
  Serial0.end();
  Serial0.begin(31250);
}

void loop() {
  // play notes from F#-0 (0x1E) to F#-5 (0x5A):
  for (int note = 0x1E; note < 0x5A; note++) {
    //Note on channel 1 (0x90), some note value (note), middle velocity (0x45):
    noteOn(0x90, note, 0x45);
    delay(100);
    //Note on channel 1 (0x90), some note value (note), silent velocity (0x00):
    noteOn(0x90, note, 0x00);
    delay(100);
  }
}

// plays a MIDI note. Doesn't check to see that cmd is greater than 127, or that
// data values are less than 127:
void noteOn(int cmd, int pitch, int velocity) {
  Serial0.write(cmd);
  Serial0.write(pitch);
  Serial0.write(velocity);
}

But unfortunately no change. TX light is blinking with this code, but no message if plugged to USB of computer... As before, only works if powered using adapter.

Also posting build command in case it may help:

Code: Select all
