##### How to use this driver #####

|
(#) Enable the CAN controller interface clock using
|
|
RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN1, ENABLE); for CAN1
|
|
and RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN2, ENABLE); for CAN2
|
|
-@- In case you are using CAN2 only, you have to enable the CAN1 clock.
|
|
|
|
(#) CAN pins configuration
|
|
(++) Enable the clock for the CAN GPIOs using the following function:
|
|
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
|
|
(++) Connect the involved CAN pins to AF9 using the following function
|
|
GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_CANx);
|
|
(++) Configure these CAN pins in alternate function mode by calling
|
|
the function GPIO_Init();
|
|
|
|
(#) Initialise and configure the CAN using CAN_Init() and
|
|
CAN_FilterInit() functions.
|
|
|
|
(#) Transmit the desired CAN frame using CAN_Transmit() function.
|
|
|
|
(#) Check the transmission of a CAN frame using CAN_TransmitStatus()
|
|
function.
|
|
|
|
(#) Cancel the transmission of a CAN frame using CAN_CancelTransmit()
|
|
function.
|
|
|
|
(#) Receive a CAN frame using CAN_Recieve() function.
|
|
|
|
(#) Release the receive FIFOs using CAN_FIFORelease() function.
|
|
|
|
(#) Return the number of pending received frames using
|
|
CAN_MessagePending() function.
|
|
|
|
(#) To control CAN events you can use one of the following two methods:
|
|
(++) Check on CAN flags using the CAN_GetFlagStatus() function.
|
|
(++) Use CAN interrupts through the function CAN_ITConfig() at
|
|
initialization phase and CAN_GetITStatus() function into
|
|
interrupt routines to check if the event has occurred or not.
|
|
After checking on a flag you should clear it using CAN_ClearFlag()
|
|
function. And after checking on an interrupt event you should
|
|
clear it using CAN_ClearITPendingBit() function. </pre><pre class="fragment">@attention
