Abstract

The invention provides a DMA-based high-speed AD sampling data transmission method. The method comprises the following steps: configuring timer parameters, configuring direct memory access parameters, starting equipment, sampling data and circularly sampling. The invention relates to electronic equipment, a storage medium, a program product and a DMA-based high-speed AD sampling data transmission device. According to the invention, high-speed AD data transmission is realized by virtue of three on-chip internal and external devices, namely a timer with a signal capturing capability, a DMA (direct memory access) and a DMAMUX (direct memory access request multiplexer) in a microprocessor, and matching with a GPIO interface and an AD sampling chip parallel interface of an analog ADC series. The AD sampling data can be directly transmitted to the memory of the microprocessor through the DMA, so that the occupation of CPU resources is greatly reduced, the development cost and the material cost are saved, and the stability and the correctness of data transmission are improved.

Description

technical field [0001] The invention relates to the technical field of high-speed AD sampling of embedded equipment, in particular to a DMA-based high-speed AD sampling data transmission method, equipment, medium, product and device. Background technique [0002] Most of the high-speed AD sampling chips commonly used in the market are ADC series of ADI Company, but the common microprocessors in the market do not provide data transmission interfaces matching the AD sampling chips of the ADC series. The commonly used solution in the market is to use the GPIO interface of the microprocessor to simulate the parallel interface of the AD sampling chip of the ADC series for data transmission. This solution will occupy a large amount of resources of the CPU, resulting in a decrease in the performance of the microprocessor, and even needs to add an additional processor for other business processing, resulting in an increase in development costs and material costs.
