Can't compile Synthselect was not declared

[KeenVox]

Hi, I can't get the code to compile. It always stops at "Syntselect was not declared in this scope". I'm using the Audikit V2.2. Board in the manager ist ESP32 DEV Modul. Version 1.0.6.n 1.04 makes no difference. I tried some different arduino versions, but didn't work. Any advice? Thanks!

seems to be the same or I copied it in the wrong place. If I put it after void loop () nothing seems to happen. It just stops with ff

Hm should look like this:

Generated with this code:

        if (Serial2.available())
        {

If I try that I get 'Midi_SendShortMessage' was not declared in this scope while compiling.

[marcel-licence]

Okay the ff is your first received byte via midi. If you hit any keys you should get some output

[KeenVox]

yes looks like that: 23:15:30.355 -> Firmware started successfully 23:15:30.355 -> ff 00 20 00 00 20 00

[marcel-licence]

Hm okay that is really strange. There is no note on or note off event. There are some possible problems left:

• wrong io
• wrong baud rate
• hardware circuit

You could define another PIN MIDI_RX_PIN

The baudrate is defined by MIDI_SERIAL2_BAUDRATE

[KeenVox]

what baud rate should I try? and the io pin? Just on of the other pins of teh audiokit?

[marcel-licence]

#define MIDI_SERIAL2_BAUDRATE 31250 that should be correct. Yes you can try another free IO expect IO0 and IO5 (this is for MCLK and Boot)

[KeenVox]

okay I changed to IO 23, the D5 LED is now blinking, but I have sound!

[marcel-licence]

Can you play notes?

[KeenVox]

Yes works as it should, I would say. 93322c>93 32 2c 00:07:07.576 -> 833240>83 32 40 00:07:08.327 -> 93324e>93 32 4e 00:07:08.468 -> 833240>83 32 40 00:07:08.655 -> 93324f>93 32 4f 00:07:08.749 -> 833240>83 32 40 00:07:09.265 -> 93323f>93 32 3f 00:07:09.358 -> 833240>83 32 40 00:07:09.639 -> 933238>93 32 38 00:07:09.733 -> 833240>83 32 40 00:07:09.980 -> 93324a>93 32 4a 00:07:10.121 -> 833240>83 32 40 00:07:10.355 -> 933425>93 34 25 00:07:10.542 -> 833440>83 34 40 00:07:10.777 -> 933438>93 34 38 00:07:10.917 -> 833440>83 34 40 00:07:11.163 -> 933432>93 34 32 00:07:11.256 -> 833440>83 34 40

[marcel-licence]

Hooray. That looks perfect. Do we know the issue?

[KeenVox]

Seems to be the IO Pin. I changed from 19 to 23 and everything works like it should :-) What's nice to, If I connect my usb midi controller to the usb/uart port of the audio kit it does work to, without changing anything in the code. my controler even gets his power from the audio kit. that's nice. :-D

[marcel-licence]

I am happy to hear that. Is the other LED still blinking every second? I found a BLINK_LED_PIN config which might create a conflict on the MIDI input signal.

[KeenVox]

In the moment it's blinking every second. Before we changed it to IO23 it blinked for every midi signal it received. Was that the purpose?

[marcel-licence]

The blink LED should just blink as indicator that the firmware is still running. That explains the 00 and FF in the debug output before. I am now cleaning up the pin configuration files =) So finally that explains your observed problem. The change to the ES8388 is really bad. I've noted down a lot of configurations.

[KeenVox]

Yeah, thank you for all your help! Hope you start selling your pcb soon, I could really need one 😉

[marcel-licence]

Sounds like a plan =) I've updated now the configuration files. Hope this will make the configuration in future a bit easier
