Problems solved by technology

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 prosthetic extracorporeal devices are powered by lithium batteries, which are sensitive to power consumption

Abstract

The invention relates to a serial data receiving method and system based on STM32. The method comprises the following steps: receiving an OOK radio frequency signal through an onboard wireless communication chip, and demodulating a defective Manchester data signal; receiving a defective Manchester data signal, converting the Manchester data signal into a series of ADC data corresponding to a waveform, and caching the ADC data in a first array in a DMA receiving mode by an ADC module of the STM32 ; calling an ADC data processing function to convert the ADC data into corresponding Manchester coded data; decoding the Manchester coded data stored in the second array through a Manchester decoding function, and caching the Manchester coded data in a third array; pre-defining C language structure pointer according to a data packet protocol, and then reading out specific data and content cached in a third array. According to the invention, serial data can be directly received, and the cost and power consumption of a hardware circuit are reduced.

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 ...
