SERIAL COMMUNICATION METHOD AND DEVICE THEREOF

摘要

Disclosed is a new serial communication method, comprising: sending serial communication data at a first clock frequency, characterized in that, when the sending of the serial communication data fails, the first clock frequency is adjusted to a second clock frequency to send the serial communication data. The existing method for enhancing an anti-interference capability of serial communication greatly increases the costs and complexity of system hardware due to adding a filter circuit, optimizing a PCB layout and adding a shielding case in the hardware aspect, or enhancing data checking during data transmission and adding a watchdog mechanism in the software aspect. The method according to the present invention is simple and practicable, the costs and complexity of system hardware are almost not increased, and the anti-interference effect is significantly improved.
