Electrical note to connect UART MIDI keyboard

[sysop8866]

Hello!
I suggest you insert a 470ohm pullup resistor between pin(7)-GPIO5 Rx MIDI and 3.3V.
Without this resistor I cannot decode any data from the MIDI keyboard.
Now with this modification it works perfectly.
I compiled your software for both the RP2040 and RP2350 boards with an external DAC PCM5102 and it works well.
I congratulate you for the excellent work you have done.
Thanks
Daniele
P.S.
Sorry for my bad English!
