回调函数和半回调函数都是通过DMA1_Stream0_IRQHandler中断进入。 具体ADC同步DMA采集介绍,可以回顾基础实验 “实验二十四 ADC定时器触发配合DMA双缓冲实现实时采集” 在程序中,添加了串口打印函数printf用于发送数据到上位机,可以回顾基础实验 “实验十六 串口通信” 3. 程序解读 登录后复制while(1) {if(g_adc1_dma...

43.2.1 定时器选择 使用DMA的话,请求信号都是来自DMAMUX2,而控制DMA做周期性传输的话,可以使用定时器触发,这样的话就可以使用DMAMUX的请求发生器功能,支持如下几种触发: #define HAL_DMAMUX1_REQ_GEN_DMAMUX1_CH0_EVT 0U #define HAL_DMAMUX1_REQ_GEN_DMAMUX1_CH1_EVT 1U ...
1、启动文件简介 启动文件由汇编编写,是系统上电复位后第一个执行的程序。主要做了以下工作: (1)初始化堆栈指针 MSP=_initial_sp (2)初始化 PC 指针=Reset_Handler (3)初始化中断向量表 (4)配置系统时钟 LDR R0, =SystemInit (5)调用 C 库函数_main 初始化用户堆栈,从而最终调用 main 函数去到 C 的世...
