Ideas for stm32 to pc comms via radio
Posted: Mon May 18, 2020 5:46 pm
Hi all!
Im working on a project where I am building a flight control system for a model aircraft using the stm 32.
The system is compromised of 2 parts, the flight controller (and sensors fitted to the aircraft) and a windows application (.net/c#). Part of the goal is to have a fast telemetry link between the 2 so you can see what the aircraft is doing in real time.
The telemetry link consists of simple 3DR radios that connects to the stm32 via serial and to a pc over usb connection.
My question is has anyone had any experiance with telemetry protocols over these sorts of radios? i have a large number of variables that need to be transmitted back and forth. So far ive user a system where a certain character is used to identify each variable such as P090 for a pitch of 090. The problem is that this seems to be unreliable. Anyone have any advice?
Thanks, George
