Digital signal processor (DSP)-based serial port data receiving-transmitting method of guidance control over vertical take-off and landing aircraft

[0026] A DSP-based serial port data sending and receiving method for vertical take-off and landing aircraft guidance control, said method comprising:

[0027] Step 1. Start to send and receive serial data;

[0028] Step 2, parameter initialization: parameter initialization of serial port communication, parameter initialization for VTOL aircraft guidance control and initialization of DSP chip parameters;

[0029] Step 3, disable interrupt: first turn off the global interrupt, and then clear the interrupt flag in the interrupt number;

[0030] Step 4, open the configuration device: open the serial port, and initialize the properties of the serial port, wherein the serial port properties include data bits, parity bits, stop bits and baud rate;

[0031] Step 5, setting interrupt: set the serial port receiving data interrupt condition, the flag bit and the interrupt source occupied respectively, wherein, the serial port receiving data interrupt condition is that the data in the bu...
