STM32的AD转换，连续转换模式，通过DMA通过读取，每隔一秒向串口发送一次-The AD conversion STM32, continuous conversion mode, by reading through the DMA, to the serial port once every second

基于STM32单片机的TIM2定时器触发AD转换，控制AD的转换速率，弥补DMA传输速度过快导致数据处理混乱的问题。-Trigger AD conversion is based STM32 microcontroller TIM2 timer controls the AD conversion rate to make up for excessive speed DMA transfer of data processing leads to confusion problems.

STM32的ADC程序，没有使用DMA和中断，使用扫描的方式读取AD值-STM32 ADC

STM32以DMA方式读取内部AD数据的程序-STM32 internal AD data read program in DMA way
