Setting up RPi MIDI #2 #piday #raspberrypi @Raspberry_Pi

Via Zuzebox’s blog

In a previous post on setting MIDI baud-rates on the RPi I used a slight of hand (i.e. init_uart_clock etc.) to trick the RPi in setting the UART to a 31250 baud needed for MIDI. While browsing the Raspberry Pi forum I spotted this nugget of information from PhilE:

in config.txt add:

enable_uart=1
dtoverlay=pi3-miniuart-bt
dtoverlay=midi-uart0

This combination does three things:

1) Enables the UART. It isn’t strictly necessary when combined with pi3-miniuart-bt
2) Reassigns the weaker UART (ttyS0) for Bluetooth and frees ttyAMA0 for our MIDI interface
3) Using an DT overlay to achieve the same UART clock settings as our init_uart_clock etc. trick

It makes things a lot simpler 🙂
