Traffic indicators

The current nucleo_h753zi target maps transport traffic indicators to the on-board user LEDs:

Indicator	LED
DIN input	LD1 / PB0
DIN output	LD2 / PE1
BLE input	LD1 / PB0
BLE output	LD2 / PE1
Network input	LD1 / PB0
Network output	LD2 / PE1

I2C

Signal	Pin
Vcc	5V
GND	GND
SDA	PB9
SCL	PB8

DIN MIDI

This board doesn't have DIN MIDI connectors, so they have to be added to the board with the corresponding circuitry. Use this schematic:

MIDI In	MIDI Out
PC7	PC6

Touchscreen

Screen	Pin
Vcc	5V
GND	GND
Rx	PC6
Tx	PC7

Bootloader switch

Hold OpenDeck switch 0 / PC13 active while resetting or powering the board to enter the OpenDeck bootloader. This is the blue user button.

Flashing

To flash this board with the OpenDeck firmware, go to the OpenDeck configurator and follow the instructions.

Notes

DIN MIDI and touchscreen use the same UART pins on this board, so only one of them can be enabled at a time.
