STM32F105主板HAL库函数HAL_UART_Receive_IT()中第二个参数uint8_t *pData必须为无符号整型？？
stm32f1xx_hal_uart.c文件中对HAL_UART_Receive_IT()函数的描述为
- HAL_StatusTypeDef HAL_UART_Transmit_IT(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size)
- {
- /* Check that a Tx process is not already ongoing */
- if(huart->gState == HAL_UART_STATE_READY)
- {
- if((pData == NULL) || (Size == 0U))
- {
- return HAL_ERROR;
- }
- /* Process Locked */
- __HAL_LOCK(huart);
-
- huart->pTxBuffPtr = pData;
- huart->TxXferSize = Size;
- huart->TxXferCount = Size;
-
- huart->ErrorCode = HAL_UART_ERROR_NONE;
- huart->gState = HAL_UART_STATE_BUSY_TX;
-
- /* Process Unlocked */
- __HAL_UNLOCK(huart);
-
- /* Enable the UART Transmit data register empty Interrupt */
- __HAL_UART_ENABLE_IT(huart, UART_IT_TXE);
-
- return HAL_OK;
- }
- else
- {
- return HAL_BUSY;
- }
- }
本人使用串口中断接收温度数据，而温度数据是有符号整型的，与上述函数定义矛盾，请问应该怎样更改呢？？
