STM32F103 CubeMX ADC 驱动 PS2游戏摇杆控制杆传感器模块_stm32f103 cube debug

1. 工程配置

1.1 配置debug口

1.2 配置时钟

1.3 配置ADC

1.4 配置串口

1.5 配置时钟

这里时钟配置成了72M，

1.6 生成工程

2. 代码编写

2.1 串口代码

/* USER CODE BEGIN 0 */
#include <stdio.h>
 //重定向c库函数printf到串口USARTx，重定向后可使用printf函数
 int fputc(int ch, FILE *f)
 {
     /* 发送一个字节数据到串口USARTx */
     HAL_UART_Transmit(&huart1, (uint8_t *)&ch, 1, 0xFFFF);
     return (ch);
 }
/* USER CODE END 0 */
