bogdanm	0:9b334a45a8ff	19	[..]
bogdanm	0:9b334a45a8ff	20	(#) Enable the CAN controller interface clock using
bogdanm	0:9b334a45a8ff	21	__HAL_RCC_CAN1_CLK_ENABLE() for CAN1 and __HAL_RCC_CAN2_CLK_ENABLE() for CAN2
bogdanm	0:9b334a45a8ff	22	-@- In case you are using CAN2 only, you have to enable the CAN1 clock.
bogdanm	0:9b334a45a8ff	23
bogdanm	0:9b334a45a8ff	24	(#) CAN pins configuration
bogdanm	0:9b334a45a8ff	25	(++) Enable the clock for the CAN GPIOs using the following function:
bogdanm	0:9b334a45a8ff	26	__HAL_RCC_GPIOx_CLK_ENABLE()
bogdanm	0:9b334a45a8ff	27	(++) Connect and configure the involved CAN pins to AF9 using the
bogdanm	0:9b334a45a8ff	28	following function HAL_GPIO_Init()
bogdanm	0:9b334a45a8ff	29
bogdanm	0:9b334a45a8ff	30	(#) Initialize and configure the CAN using HAL_CAN_Init() function.

bogdanm	0:9b334a45a8ff	40	using HAL_CAN_Transmit(), at this stage user can specify the value of timeout
bogdanm	0:9b334a45a8ff	41	according to his end application
bogdanm	0:9b334a45a8ff	42	(+) Start the CAN peripheral reception and wait the end of this operation
bogdanm	0:9b334a45a8ff	43	using HAL_CAN_Receive(), at this stage user can specify the value of timeout

bogdanm	0:9b334a45a8ff	50	(+) Start the CAN peripheral reception using HAL_CAN_Receive_IT()
bogdanm	0:9b334a45a8ff	51	(+) Use HAL_CAN_IRQHandler() called under the used CAN Interrupt subroutine
bogdanm	0:9b334a45a8ff	52	(+) At CAN end of transmission HAL_CAN_TxCpltCallback() function is executed and user can
bogdanm	0:9b334a45a8ff	53	add his own code by customization of function pointer HAL_CAN_TxCpltCallback
bogdanm	0:9b334a45a8ff	54	(+) In case of CAN Error, HAL_CAN_ErrorCallback() function is executed and user can
