四旋翼飞行器在MATLABsimulink仿真系统和程序。

本程序会将WIFI模块发送的数据转发到USART1串口，同时将USART1串口接收到的数据转发给WIFI模块。这样客户就可以通过HL-340的USB转RS232串口线来测试WIFI模块的AT指令了。(The data in this program will be forwarded to the WIFI module sending USART1 serial port, while forwards USART1 receive serial data to WIFI module. So customers can be transferred via RS232 serial cable HL-340' s USB WIFI AT command to test the module.)
