桥接功能(STLINK-V3MODS only)
Bridge SPI
SPI signals are available on CN2 pins 7, 14, 23 and 25.
Bridge I2C
I2C signals are available on CN2 pins 16 and 17. It is necessary to add externally 680 Ω
pull-up resistors on the host application board.
Bridge CAN
CAN logic signals (Rx/Tx) are available on CN2 pins 9 and 10, they may be used as input
for an external CAN transceiver.
Bridge UART
UART signals with hardware flow control (CTS/RTS) are available on CN2 pins 1 to 3 and
11. They need a dedicated firmware to be programmed on the main module before being
used. Without this firmware, the Virtual COM port function must be used instead (no
hardware flow control).
