我想要一个代码，通过具有以下设置的stm32f732控制器读取 ad7699： IN[7：0] 单极性参考 GND，按顺序排序 单极点滤波器的全带宽 内部基准电压源/温度传感器禁用，缓冲器启用 启用序列器 无CFG寄存器回读

以下是一个示例代码，可以通过STM32F732控制器读取AD7699：

#include "stm32f7xx.h"

#define ADC_CS_PIN       GPIO_Pin_4
#define ADC_CS_PORT      GPIOA

void SPI_init(void)
{
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);
    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);

    GPIO_InitTypeDef GPIO_InitStruct;
    GPIO_InitStruct.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_7;  // SCK and MOSI
    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF;
    GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
    GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
    GPIO_Init(GPIOA, &GPIO_InitStruct);

    SPI_InitStruct.SPI_CPHA = SPI_CPHA_1Edge;
    SPI_InitStruct.SPI_NSS = SPI_NSS_Soft;
    SPI_InitStruct.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_2;
    SPI_InitStruct.SPI_FirstBit = SPI_FirstBit_MSB;
    SPI_InitStruct.SPI_CRCPolynomial = 7;
    SPI_Init(SPI1, &SPI_InitStruct);

    SPI_Cmd(SPI1, ENABLE);
}

void ADC_init(void)
{
    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOB, ENABLE);

    GPIO_InitTypeDef GPIO_InitStruct;
    GPIO_InitStruct.GPIO_Pin = GPIO_Pin_1;  // SYNC
    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT;
    GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
    GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
    GPIO_Init(GPIOB, &GPIO_InitStruct);

    GPIO_SetBits(GPIOB, GPIO_Pin_1);

    // write to configuration register
    GPIO_ResetBits(ADC_CS_PORT, ADC_CS_PIN);
    uint16_t cmd = 0x0000;
    cmd |= (1 << 15);  // enable sequencer
    cmd |= (1 << 14);  // use internal reference
    cmd |= (1 << 10);  // disable temperature sensor
    cmd |= (1 << 9);   // enable buffer
    cmd |= (1 << 8);   // continuous conversion mode
    SPI_I2S_SendData(SPI1, cmd);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    GPIO_SetBits(ADC_CS_PORT, ADC_CS_PIN);

    // wait for configuration to take effect
    delay_us(100);
}

uint16_t read_ADC(uint8_t channel)
{
    GPIO_ResetBits(ADC_CS_PORT, ADC_CS_PIN);

    uint16_t cmd = 0x8000;
    cmd |= ((channel & 0x07) << 12);  // select channel
    SPI_I2S_SendData(SPI1, cmd);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    uint16_t data = SPI_I2S_ReceiveData(SPI1);

    GPIO_SetBits(ADC_CS_PORT, ADC_CS_PIN);

    return data;
}

这个代码使用了SPI接口进行通信，并且使用了GPIO控制AD7699的SYNC和CS信号。在初始化时，该代码将AD7699配置为启用序列器，使用内部基准电压源，禁用温度传感器，并启用缓冲器。然后，`read_ADC`函数将给定的通道号发送到AD7699，读取返回的数据并返回它。
