A method and system for receiving serial data based on stm32

Abstract

The present application relates to a serial data receiving method and system based on STM32; the method includes: receiving an OOK radio frequency signal through an onboard wireless communication chip, and demodulating a defective Manchester data signal; The ADC module receives the defective Manchester data signal, converts the Manchester data signal into a series of ADC data corresponding to the waveform, and buffers the ADC data in the first array by means of DMA reception; call ADC The data processing function converts the ADC data into corresponding Manchester encoded data; decodes the Manchester encoded data stored in the second array through the Manchester decoding function, and caches it in the third array; Define a C language structure pointer, and then read out the specific data and content cached in the third array. The invention can directly receive the serial data, and reduces the cost and power consumption of the hardware circuit.

Description

technical field [0001] The present application relates to the technical field of serial data processing, in particular to a method and system for receiving serial data based on STM32. Background technique [0002] The chip implanted in the body returns a serial data with a fixed baud rate, which does not conform to the Serial Communication protocol. There is no such directly usable serial communication peripheral device on the single-chip microcomputer or other SOC. If it is necessary to receive the data returned by the chip implanted in the body, it is generally realized by an external FPGA. Although the external FPGA is simple and direct and has relatively high efficiency, it increases the cost of the hardware circuit. At the same time, due to the external FPGA Consumes power consumption, especially the retinal prosthesis extracorporeal device is powered by a lithium battery, which is sensitive to power consumption. Contents of the invention [0003] Based on this, it ...
