Hi all,
Looking into making a 250 autopilot quadcopter build with a Pi zero as the onboard computer. I know that you can use any open UART port to communicate between the FC and Pi with Mavlink (and dronekit?), but was wondering about USART. A lot of small FC’s I’ve found have a UART telem and a USART telem. Some googling told me that a USART can be configured for asynchronous, so I assume that means it could be used as a UART for onboard computer communication. Is this correct, and if so, what would I need to do to configure the USART?
