Stm32 这是去SPI的路吗？

我目前正在尝试使用该函数检查SPI是否正常工作。 如果一切正常，这个函数应该返回1…但它总是返回0。也许pTxData中的值是错误的

uint8_t Gyro_CanReadWHOAMI() {
    uint8_t pTxData[2] = {0x0F | 0x80, 0};
    uint8_t pRxData[2] = {0, 0};
    
    HAL_GPIO_WritePin(NCS_MEMS_SPI_GPIO_Port, NCS_MEMS_SPI_Pin, GPIO_PIN_RESET);
    HAL_SPI_TransmitReceive(&hspi5, pTxData, pRxData, 2, HAL_MAX_DELAY);
    
    HAL_GPIO_WritePin(NCS_MEMS_SPI_GPIO_Port, NCS_MEMS_SPI_Pin, GPIO_PIN_SET);
    uint8_t test = pRxData[1] == 0x32;
    return test;
}

使用STM32F429I-DISC1解决了错误的值

uint8_t Gyro_CanReadWHOAMI() {

      uint8_t pTxData[2] = {0b10000000 | 0x0F, 0};

      uint8_t pRxData[2] = {0, 0};

      HAL_GPIO_WritePin(NCS_MEMS_SPI_GPIO_Port, NCS_MEMS_SPI_Pin, GPIO_PIN_RESET);
      HAL_SPI_TransmitReceive(&hspi5, pTxData, pRxData, 2, HAL_MAX_DELAY);

      HAL_GPIO_WritePin(NCS_MEMS_SPI_GPIO_Port, NCS_MEMS_SPI_Pin, GPIO_PIN_SET);
      uint8_t test = pRxData[1] == 0xD4;
      return test;

}

uint8_t Gyro_CanReadWHOAMI() {

      uint8_t pTxData[2] = {0b10000000 | 0x0F, 0};

      uint8_t pRxData[2] = {0, 0};

      HAL_GPIO_WritePin(NCS_MEMS_SPI_GPIO_Port, NCS_MEMS_SPI_Pin, GPIO_PIN_RESET);
      HAL_SPI_TransmitReceive(&hspi5, pTxData, pRxData, 2, HAL_MAX_DELAY);

      HAL_GPIO_WritePin(NCS_MEMS_SPI_GPIO_Port, NCS_MEMS_SPI_Pin, GPIO_PIN_SET);
      uint8_t test = pRxData[1] == 0xD4;
      return test;
