Multi Channel Recorder for Unmanned Aerial Vehicle Based on ARM9

For accessing data from different channel in UAV (unmanned aerial vehicle) immediately, a method for massive data and multichannel recorder system is introduced. The system hardware composition and functions are described in details. The software design of receiving program is given, including extended UART ports’ initialization and design of interruption scheme. And experiment result shows that the recorder not only record data from UAV successfully but also improve the way to hand the UAV data.
