将Uint16强制转化为uint8

uint16_t a[8];
HAL_StatusTypeDef AD7606_ReadData(uint16_t *pData, uint16_t size) {
    HAL_StatusTypeDef status;
    uint8_t rxBuffer[size * 2];
    status = HAL_SPI_Receive(&hspi1, rxBuffer, size * 2, HAL_MAX_DELAY);
    if (status == HAL_OK) {
        for (int i = 0; i < size; i++) {
            //SPI的 MSB模式
            pData[i] = (uint16_t)(rxBuffer[2 * i] << 8 | rxBuffer[2 * i + 1]);
        }
    }
    return status;
}
用法：AD7606_ReadData(a,8);
