Abstract

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. The CAN controller bit parameter setting method includes: obtaining the constraint condition of the bit parameter of the CAN controller; according to the constraint condition of the bit parameter and the preset CAN controller clock frequency f clk , sampling point SP, bit rate BR, calculating the value of the CAN bit parameter; setting the bit parameter of the CAN controller according to the value of the CAN bit parameter. The technical scheme of the present application, the method of obtaining CAN bit parameters is simple and reasonable, can quickly obtain reasonable CAN bit parameters, avoids the problem of slow speed of obtaining CAN bit parameters caused by manual calculation, and also avoids calculation errors, so that CAN can be quickly set The bit parameters of the controller, 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...
