Pb with M5Unit-Synth

Zorgroz

No sounds with my M5 gray aand the M5 Unit Synth using the example scripts
https://github.com/m5stack/M5Unit-Synth/tree/main/examples

Have you tested these scripts?
Thanks for your help.

Yes, I have tried the examples that Zorgroz refers to using my M5 Core2 and the M5 Unit Synth.
No sounds are heard. Only the green title on the screen "Unit Synth Drum".

Is there any documentation on how to use the M5Unit Synth with M5Flow?
Thanks

Hello @Kombistack
With Arduino IDE, Core2 AWS and when I use Port C Blue the examples works.

You need to change RX 16 to 13 and TX 17 to 14 in the INO sketch :
synth.begin(&Serial2, UNIT_SYNTH_BAUD, 13, 14);

And in the file "M5UnitSynth.h":
void begin(HardwareSerial *serial = &Serial2, int baud = UNIT_SYNTH_BAUD,
uint8_t RX = 13, uint8_t TX = 14);

Happy Midi ;-)
