Hi,

i'm working with little project on STM32F105, but libraries have never been corrected from STM and bugs are presents also on last version

* @version V1.0.4

* @date 29-April-2016

.

Now i have a little doubts about STM library, on HAL_CAN_Receive_IT function.

First question is:

Its correct enable the Transmit mailbox empty Interrupt (CAN_IT_TME ) on receive ?

Secondt question:

Its correct to UNLOCK the can before enable the message pending Interrupt (CAN_IT_FMP0 or CAN_IT_FMP1) ? Or is better enable all needed interrupt and unlock after ?

Sorry for my english

/* Enable interrupts: */

/* - Enable Error warning Interrupt */

/* - Enable Error passive Interrupt */

/* - Enable Bus-off Interrupt */

/* - Enable Last error code Interrupt */

/* - Enable Error Interrupt */

/* - Enable Transmit mailbox empty Interrupt */

/* __HAL_CAN_ENABLE_IT(hcan, CAN_IT_EWG |

CAN_IT_EPV |

CAN_IT_BOF |

CAN_IT_LEC |

CAN_IT_ERR |

CAN_IT_TME );

__HAL_UNLOCK(hcan); // its correct this line here ?

if(FIFONumber == CAN_FIFO0)

{

// Enable FIFO 0 message pending Interrupt //

__HAL_CAN_ENABLE_IT(hcan, CAN_IT_FMP0);

}

else

{

// Enable FIFO 1 message pending Interrupt //

__HAL_CAN_ENABLE_IT(hcan, CAN_IT_FMP1);

}*/
