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 */
2.2 ADC读取数据的代码
/*** @brief The application entry point.* @retval int*/
int main(void)
{/* USER CODE BEGIN 1 *//* USER CODE END 1 *//* MCU Configuration--------------------------------------------------------*//* Reset of all peripherals, Initializes the Flash interface and the Systick. */HAL_Init();/* USER CODE BEGIN Init *//* USER CODE END Init *//* Configure the system clock */SystemClock_Config();/* USER CODE BEGIN SysInit *///USB 卸载操作，取消按复位键后无法识别的问题USB_Disconnected();/* USER CODE END SysInit *//* Initialize all configured peripherals */MX_GPIO_Init();MX_ADC1_Init();MX_TIM2_Init();MX_TIM3_Init();MX_USART1_UART_Init();MX_USB_DEVICE_Init();MX_ADC2_Init();/* USER CODE BEGIN 2 */HAL_TIM_Encoder_Start(&htim2, TIM_CHANNEL_ALL);HAL_TIM_Encoder_Start(&htim3, TIM_CHANNEL_ALL);//2.添加数组unsigned char enter[100] = {0};uint16_t ADC0_Value=0;uint16_t ADC1_Value=0;char ADcKey = 0;char DirectionA = 0;short CaptureNumberA =0;/* USER CODE END 2 *//* Infinite loop *//* USER CODE BEGIN WHILE */while (1){//get adc data HAL_ADC_Start(&hadc1);HAL_ADC_PollForConversion(&hadc1, HAL_MAX_DELAY);ADC0_Value = (uint16_t)HAL_ADC_GetValue(&hadc1);HAL_ADC_Start(&hadc2);HAL_ADC_PollForConversion(&hadc2, HAL_MAX_DELAY);ADC1_Value = (uint16_t)HAL_ADC_GetValue(&hadc2); ADcKey = HAL_GPIO_ReadPin(GPIOB,GPIO_PIN_8);//获得脉冲//DirectionA = __HAL_TIM_IS_TIM_COUNTING_DOWN(&htim2); CaptureNumberA=__HAL_TIM_GET_COUNTER(&htim2);/* USER CODE END WHILE *//* USER CODE BEGIN 3 */HAL_Delay(100);sprintf(enter,"ADC0:%d,ADC1:%d,ADC_key: %d CaptureNumberA:%d \r\n",ADC0_Value,ADC1_Value,ADcKey,CaptureNumberA);CDC_Transmit_FS(enter,sizeof(enter)); //USB 串口发送数据}/* USER CODE END 3 */
