What's the best protocol (USART mode?) for high-speed bidirectional comm between two STM32s?
I’m designing a motor control PCB with two STM32G432RBs (situated close to each other on the PCB) driving a boatload of H-Bridges, encoders, servos, and other I/O. I’m planning a dedicated (synchronous) USART connection between the two STM32G4s to ke...
