Hello Friends,
I have a stm32f4 discv. board and need to drive 6 motor drivers independently that have RS422 interface (just send command, no pwm calc.) How can i do that with discv board or in new designing ? Is 1 usart, 1 rs422 tranceiver is enough, if so is there any example for this scenario or can someone share a small code block for just controlling specific slave device among many slaves?
A simple topology i want to design is like that:
