Abstract

The invention discloses an SPI asynchronous communication scheduling method and device, equipment and a storage medium. The method comprises the steps that when an asynchronous transmission task is detected, calling an in-column operation instruction to put a task number corresponding to the asynchronous transmission task into a task queue, and adjusting the task state to be a waiting state; when the periodic trigger signal is received, calling a column-out operation instruction to obtain a target task number and a target task state corresponding to the to-be-transmitted task from the task queue; when the target task state is a waiting state and the current SPI transmission channel is in an idle state, entering an execution state; and executing an SPI asynchronous transmission operation on the to-be-transmitted task according to a target execution function corresponding to the target task number. Through the above mode, scheduling management can be performed on a plurality of SPI asynchronous transmission requests generated in a short time, so that transmission errors are reduced, SPI asynchronous communication is realized, and time delay in a communication process is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an SPI asynchronous communication scheduling method, device, equipment and storage medium. Background technique [0002] Automotive motor controllers will use a large number of peripheral chips, some of which need to write driver software. The main control chip of the motor controller generally uses the SPI communication method to communicate with the peripheral chip. SPI communication methods are divided into synchronous and asynchronous. Due to its simple time model, the synchronous communication method does not need to pay too much attention to the scheduling timing of the function interface during programming, which makes this communication method the preferred SPI communication solution. However, when the amount of transmitted data increases, the time delay caused by synchronous waiting will also increase. Especially in order to ensure the communication qua...
