Abstract

The invention relates to the technical field of automobile control, in particular to a CAN controller bit parameter setting method, device and equipment and a storage medium. The CAN controller bit parameter setting method comprises the following steps: acquiring constraint conditions of bit parameters of a CAN controller; calculating the value of the CAN bit parameter according to the constraintcondition of the bit parameter, a preset CAN controller clock frequency fclk, a sampling point SP and a bit rate BR; and setting the bit parameter of the CAN controller according to the value of the CAN bit parameter. According to the technical scheme of the invention, the method for obtaining the CAN bit parameters is simple and reasonable, the reasonable CAN bit parameters can be quickly obtained, the problem that the speed of obtaining the CAN bit parameters is low due to manual calculation is avoided, calculation errors are also avoided, and therefore the bit parameters of the CAN controller can be quickly set, and the set bit parameters of the CAN controller are accurate.

Description

technical field [0001] The present application relates to the technical field of automobile control, in particular to a CAN controller bit parameter setting method, device, equipment and storage medium. Background technique [0002] In a complete CAN bus network, the baud rate of all nodes in the network should be the same, or almost the same. The CAN bus needs to set bit parameters. In the prior art, when setting the bit parameters of the CAN controller, it is generally calculated manually, the process is cumbersome and complicated, and may be prone to errors. [0003] Therefore, how to provide a simple solution for setting CAN bit parameters is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The present application provides a CAN controller bit parameter setting method, device, equipment and storage medium, aiming at solving the technical problem of troublesome CAN controller bit parameter setting. [0005] In t...
