Abstract

The invention discloses a UART communication system; based on an existing UART communication system, the low-speed UART directly connected with an initial clock source is added; the low-speed UART isdirectly connected with the initial clock source, so the working clock frequency of the low-speed UART is lowest; correspondingly, when the low-speed UART works, the frequency of the data transmittedand received by the low-speed UART is the lowest, and the power consumed when the data is transmitted and received is the lowest, so that the UART communication system disclosed by the invention can work in a low-power-consumption environment by means of the low-speed UART; and the power consumption of the UART communication system can be reduced to a certain extent compared with the prior art. The UART communication method, device and a computer storage medium disclosed by the invention also solve the corresponding technical problems.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a UART communication system, method, device and computer storage medium. Background technique [0002] In the existing UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver Transmitter) system, each UART is connected with DMA (DirectMemory Access, direct memory access) through APB (Advanced Peripheral Bus, external bus), and DMA passes AHB ( Advanced High Performance Bus, advanced high-performance bus) is connected with MCU (Microcontroller Unit, micro control unit), and MCU is connected with high-speed peripherals through AHB bus. The high-speed peripherals mentioned here include GPIO (General Purpose Input Output, general purpose input / output), SRAM (Static Random Access Memory), FLASH, etc.; the output port of 32KXTAL (32K external crystal oscillator) is connected to the input terminal of the PLLL frequency multiplication mo...
