|
|
|
|
|
* This example demonstrates how to send MIDI data via Uart
|
|
|
|
|
* interface on STM32 family.
|
|
|
|
|
*
|
|
|
|
|
* This example code is in the public domain. |
|
|
|
|
* |
|
|
|
|
* ... |
|
|
|
|
* Requires STM32Duino board manager to be installed. |
|
|
|
|
*
|
|
|
|
|
* Define HardwareSerial using any available UART/USART.
|
|
|
|
|
* Nucleo boards have UART/USART pins that are used by the ST-LINK interface (unless using solder bridging). |
|
|
|
|
* |
|
|
|
|
* Tested on Nucleo-F401RE and Nucleo-F072RB (PA9=D8 PA10=D2 on the Arduino pins) |
