I create a project with cubeMX & Arm_MDK(keil) for stm32f4 discovery.
T want learn uart interrupt driven .my code:
//------------------------------------------------------------------------
UART_HandleTypeDef huart6;
int
main(
void
)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_USART6_UART_Init();
HAL_UART_Receive_IT(&huart6, (uint8_t *)aRxBuffer, 8);
while
(1)
{
HAL_GPIO_WritePin(GPIOD,GPIO_PIN_13,GPIO_PIN_SET);
HAL_Delay(1000);
}
}
void
HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle)
{
HAL_GPIO_WritePin(GPIOD,GPIO_PIN_14,GPIO_PIN_SET);
}
//------------------------------------------------------------------------
in stm32f4xx_hal_msp.c I find this code:
/* System interrupt init*/
HAL_NVIC_SetPriority(USART6_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(USART6_IRQn);
in stm32f4xx_it.c I find:
void
USART6_IRQHandler(
void
)
{
HAL_UART_IRQHandler(&huart6);
}
but
HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle) not work and GPIOD-pin-14 not on.
is there a bug in cubeMX? or .....
thank
ramin
