PCI8622数据采集卡，基于PCI总线，AD采集DMA方式采集源码-PCI8622 data acquisition card based on PCI bus, AD acquisition mode DMA capture source

stm32 AD与DMA联合调用进行模拟采样-stm32 AD and DMA calls to simulate the sampling

在STM32单片机上采用DMA采集3路AD信号，通过串口发送-3-way acquisition using DMA AD signals on STM32 microcontroller via serial port to send

通过STM32F407内置的12位adc对外部的模拟信号进行采集，利用DMA进行数据传输以提高CPU的使用效率，最后将ADC采集到的数据显示在3.4寸的液晶触摸屏上。(Through the 12 bit STM32F407 built-in ADC external analog signal acquisition, using DMA data transmission, in order to improve the use efficiency of CPU, and finally
