我想要一个代码来读取 adc ad7699 的 STM32F732 控制器出厂设置

以下是一个基本的代码示例，用于读取ADC AD7699的出厂设置：

#include "stm32f7xx.h"
#include "stm32f7xx_hal.h"

#define SPI_TIMEOUT 10000

SPI_HandleTypeDef hspi1;

void Error_Handler(void);

int main(void)
{
    uint16_t adc_config = 0;
    uint8_t tx_data[2] = {0x00, 0x00};
    uint8_t rx_data[2] = {0x00, 0x00};

    HAL_Init();
    __HAL_RCC_SPI1_CLK_ENABLE();

    GPIO_InitTypeDef GPIO_InitStruct;
    GPIO_InitStruct.Pin = GPIO_PIN_5 | GPIO_PIN_6 | GPIO_PIN_7;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

    hspi1.Instance = SPI1;
    hspi1.Init.Mode = SPI_MODE_MASTER;
    hspi1.Init.Direction = SPI_DIRECTION_2LINES;
    hspi1.Init.DataSize = SPI_DATASIZE_16BIT;
    hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;
    hspi1.Init.CLKPhase = SPI_PHASE_1EDGE;
    hspi1.Init.NSS = SPI_NSS_SOFT;
    hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_64;
    hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
    hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
    hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
    hspi1.Init.CRCPolynomial = 7;
    if (HAL_SPI_Init(&hspi1) != HAL_OK) {
        Error_Handler();
    }

    // Send command to read ADC configuration
    tx_data[0] = 0x04; // Config register address
    HAL_SPI_Transmit(&hspi1, tx_data, 1, SPI_TIMEOUT);
    HAL_SPI_Receive(&hspi1, rx_data, 2, SPI_TIMEOUT);

    adc_config = rx_data[0] << 8 | rx_data[1];

    while(1) {
        // Do something with the ADC configuration
    }
}

void Error_Handler(void)
{
    while(1) {
        // Error occurred
    }
}

这个代码使用SPI1外设控制器来与ADC AD7699通信。通过SPI传输命令和数据，读取ADC的配置寄存器。注意，此代码仅提供了基本的SPI通信和读取ADC配置的示例，你需要根据你的具体需要进行修改。

我希望代码下载出厂设置并通过stm32f732微控制器读取adc ad7699

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：

#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。
