Problems solved by technology
If the controller is a single-core controller and does not use an operating system, then when performing the above functions, all controller resources are occupied, and other operations cannot be performed, resulting in waste of controller resources
It is acceptable for single-task applications, but it is unsatisfactory for multi-task parallel applications

The invention relates to the technical field of controllers, particularly provides an asynchronous communication processing method and device and a storage medium, and aims to solve the technical problem of how to improve the task execution efficiency of a single-core controller. Therefore, the asynchronous communication processing method provided by the embodiment of the invention is applied to a control terminal which is in communication connection with a communication module through a serial communication interface, and the method mainly comprises the following steps of: determining whether to receive and analyze cache data sent to the communication interface by the communication module or not through timeout time and an idle interruption identifier when a communication task is executed; selectively making the control terminal to execute other tasks according to the determined result, and improving the task execution efficiency of the control terminal. According to the invention, the occupancy rate of the controller is reduced, parallel operation of application tasks is realized, and the occupancy of single cycle time is low, so that the response data received by the serial port can be quickly responded, and the processing efficiency of the instruction is improved.
Description
technical field [0001] The present invention relates to the technical field of controllers, in particular to an asynchronous communication processing method, device and storage medium. Background technique [0002] Many communication modules now use asynchronous serial ports, such as 2G, 3G, 4G, NB, Bluetooth, WiFi modules, etc. The method of use is that the controller sends the corresponding command to the communication module, and waits for the communication module to return the response result. After receiving the response result, the controller analyzes the response result and performs the corresponding operation. [0003] Now usually the controller sends commands, the serial port enters the receiving state, and then the controller delays for a period of time according to the user experience, after the delay ends, parses the data received in the serial port buffer, and performs corresponding operations according to the analysis results. If the controller is a single-cor...
