Modbus stm32 driver for transport modbus paket using DMA UART TIMER in rerident mode -Modbus stm32 driver for transport modbus paket using DMA UART TIMER in rerident mode

STM32 采用DMA的方式实现ADC功能-This example describes how to use the ADC1 and DMA to transfer continuously converted data ADC1 to memory. The ADC1 is configured to convert continuously channel14. Each time an end of conversion occurs the DMA transfers

通过DMA将ADC采集到的多路ADC数据存到内存中，ADC采集通过软件触发。(The data collected by ADC is stored in memory through DMA.)
