this project use for STM32F103 .it s related to ADC convertion use for external trigger (TIM1_CC1 ), use DMA to tranfer data from memory to periherial , then use USART serial tranfer to PC , to test-this project use for STM32F103 .it s related to ADC

定时器触发ADC采样，DMA进行数据传输-TIMTrigger_AutoInjection,This example provides a descr iption of how to use a DMA channel to transfer continuously a data from a peripheral (ADC1) to another peripheral (TIM1) supporting DMA transfer.

stm32f103c8t6的ADC，码盘测速，PWM测试。ADC采用了DMA通道，测速采用TIM1双通道，PWM采用TIM3.-Stm32f103c8t6 ADC, code wheel speed, PWM test. ADC uses a DMA channel, the speed using TIM1 dual channel, PWM using TIM3.
