好的,首先你需要下载适用于STM32F732微控制器的开发环境,例如Keil或者STM32CubeIDE。然后,你需要将你的ADC AD7699连接到STM32F732微控制器上,并编写相应的代码读取ADC数据。以下是一个简单的代码示例:
```c
#include "stm32f7xx.h"
#include "stm32f7xx_hal.h"
#define ADC_CS_Pin GPIO_PIN_0
#define ADC_CS_GPIO_Port GPIOA
SPI_HandleTypeDef hspi1;
ADC_HandleTypeDef hadc1;
void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_SPI1_Init(void);
static void MX_ADC1_Init(void);
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_SPI1_Init();
MX_ADC1_Init();
while (1)
{
// 读取ADC数据
uint16_t adc_value;
HAL_GPIO_WritePin(ADC_CS_GPIO_Port, ADC_CS_Pin, GPIO_PIN_RESET);
HAL_SPI_Receive(&hspi1, (uint8_t *)&adc_value, 2, HAL_MAX_DELAY);
HAL_GPIO_WritePin(ADC_CS_GPIO_Port, ADC_CS_Pin, GPIO_PIN_SET);
// 处理ADC数据
// ...
HAL_Delay(1000);
}
}

在这个例子中,ADC使用SPI接口进行通信,片选信号连接到PA0引脚。你需要根据ADC的规格书来设置SPI参数和ADC通道,以确保正确读取数据。
