#include "stm32f4xx_hal.h" 2. 定义uart_init函数 接下来,我们定义一个名为uart_init的函数,它接受一个uint32_t类型的参数bound,用于设置UART的波特率。 c void uart_init(uint32_t bound) { // 函数体将在后续步骤中填充 } 3. 使能GPIOA和USART 在STM32F4系列微控制器上,UART通常与特定的GPIO引...

在用的是CC2540的串口0P1_2(TXD),P1_3(RXD)能够正常收发数据,在HalUARTInitDMA()串口初始化中停止位的配置U0UCR的配置没用,修改前后示波器上一个字节和另一个字节停止位都是2bit,这个停止位是不能配置还是怎么回事默认2bit停止位吗,怎么办? halDMADesc_t *ch; ...
