Attitude and altitude instrument based on DSP

Unmanned Aerial Vehicle can be referred to as UAV. This design implements a system that based on DSP to measure altitude, airspeed and attitude of UAV. The system uses DSP as the controller and operator, and uses two MS5534C and a URF03-TTL232 to measure the altitude and airspeed of UAV. To measure attitude, we need three accelerometers and three gyroscopes. SCI serial port can be used to read data from the module. This design collects the data of these sensors by query method, and uses quaternion algorithm to calculate the attitude of UAV.
