The method comprises the steps that step 1, serial data receiving and transmitting are started; step 2, parameters are initialized; step 3, disabled interrupt is carried out; step 4, configuration equipment is turned on; step 5, interrupt is set; step 6, enabling interrupt is carried out; and step 7, an endless loop is started.

Description

technical field [0001] The invention relates to a DSP-based serial port data sending and receiving method for guidance and control of a vertical take-off and landing aircraft, and belongs to the technical field of hardware-in-the-loop simulation system development. Background technique [0002] As a relatively simple and reliable communication method, serial port communication is widely used in data transmission on aircraft computers. When the hardware-in-the-loop system simulates the flight process of the actual aircraft, it should also fit the environment on the aircraft as much as possible. Therefore, it is necessary to use the serial port to realize the data transmission in the hardware-in-the-loop system. There are two main programming paths for sending and receiving data by using the serial port: query and interrupt; the former needs to set a timer to send and receive data according to a certain period of time, which makes the two parties that need to send and receive ...
