写一个rt1052读取ad7616的程序

以下是一个简单的基于RT1052读取AD7616的程序示例：

#include "fsl_adc.h"
#include "fsl_gpio.h"
#include "fsl_iomuxc.h"

#define ADC_CHANNEL 0
#define ADC_INSTANCE 0
#define ADC_CLOCK_FREQ 24000000U

#define CS_GPIO GPIO1
#define CS_PIN 13

#define SPI_MASTER SPI1
#define SPI_SSEL kSPI_Ssel0Assert

#define SPI_CLOCK_FREQ 5000000U
#define SPI_MODE kSPI_Mode0
#define SPI_DATA_WIDTH 16

#define SPI_TIMEOUT 1000000U

#define BUFFER_SIZE 16

static uint32_t s_adcValue = 0U;

static void BOARD_GPIO_Init(void)
{
    gpio_pin_config_t config = {
        kGPIO_DigitalOutput, 0,
    };
    GPIO_PinInit(CS_GPIO, CS_PIN, &config);
}

static void BOARD_SPI_Init(void)
{
    spi_master_config_t config = {0};
    SPI_MasterGetDefaultConfig(&config);
    config.baudRate_Bps = SPI_CLOCK_FREQ;
    config.dataWidth = SPI_DATA_WIDTH;
    config.mode = SPI_MODE;
    SPI_MasterInit(SPI_MASTER, &config, ADC_CLOCK_FREQ);
}

static void BOARD_ADC_Init(void)
{
    adc_config_t adcConfigStruct;
    adc_channel_config_t adcChannelConfigStruct;

    ADC_GetDefaultConfig(&adcConfigStruct);
    adcConfigStruct.clockDividerNumber = 1;
    adcConfigStruct.resolution = kADC_Resolution16Bit;

    ADC_Init(ADC_INSTANCE, &adcConfigStruct);
    ADC_EnableHardwareTrigger(ADC_INSTANCE, false);

    adcChannelConfigStruct.channelNumber = ADC_CHANNEL;
    adcChannelConfigStruct.enableInterruptOnConversionCompleted = false;

    ADC_SetChannelConfig(ADC_INSTANCE, 0, &adcChannelConfigStruct);
}

static void BOARD_SPI_SendCommand(uint16_t command)
{
    uint8_t txData[2] = {(command >> 8) & 0xFF, command & 0xFF};
    uint8_t rxData[2] = {0};
    spi_transfer_t xfer = {0};
    xfer.txData = txData;
    xfer.rxData = rxData;
    xfer.dataSize = 2;
    xfer.configFlags |= kSPI_FrameAssert;
    xfer.configFlags |= kSPI_FrameAssertAfterTransfer;

    GPIO_WritePinOutput(CS_GPIO, CS_PIN, 0);
    SPI_MasterTransferBlocking(SPI_MASTER, &xfer);
    GPIO_WritePinOutput(CS_GPIO, CS_PIN, 1);
}

static uint16_t BOARD_SPI_ReadData(void)
{
    uint8_t txData[2] = {0x00, 0x00};
    uint8_t rxData[2] = {0};
    spi_transfer_t xfer = {0};
    xfer.txData = txData;
    xfer.rxData = rxData;
    xfer.dataSize = 2;

    GPIO_WritePinOutput(CS_GPIO, CS_PIN, 0);
    SPI_MasterTransferBlocking(SPI_MASTER, &xfer);
    GPIO_WritePinOutput(CS_GPIO, CS_PIN, 1);

    return (rxData[0] << 8) | rxData[1];
}

int main(void)
{
    BOARD_GPIO_Init();
    BOARD_SPI_Init();
    BOARD_ADC_Init();

    while (1)
    {
        BOARD_SPI_SendCommand(0x8000);
        s_adcValue = BOARD_SPI_ReadData();
        printf("ADC Value: %d\r\n", s_adcValue);
        BOARD_SPI_SendCommand(0x0000);
        s_adcValue = BOARD_SPI_ReadData();
        printf("ADC Value: %d\r\n", s_adcValue);

        /* Delay for 1 second */
        for (int i = 0; i < 10000000; i++)
        {
            __asm("nop");
        }
    }
}

这个程序使用了RT1052的ADC模块和SPI模块来读取AD7616芯片。首先，需要初始化GPIO、SPI和ADC，然后在主循环中发送命令到AD7616芯片，在读取数据后打印出来，并且重复此过程。请注意，这个程序只是一个简单的示例，并且可能需要根据你的实际应用进行调整。
