Hello,

We are using STM32F030 in our project. We are using RS485 half duplex communication for interaction with other boards in our system. Using the same half duplex communication channel, we would like to update the firmware in the controller in our system without access to our boards.

we are using the below pins for rs485 communication

RTS_DE is used to control the direction of RS485 communication.

PA14 for TX

PA15 for RX.

Thanks

Ravi
