Hi every body

some week ago I ported refernce emwin project to my customized board, it seems to work good. but when I tried to use CAN but faild to callback interupt routin! even I can't blink an LED on it!
I added drivers sources and included header files, and here is code I worte:

void MainTask (void) {

PINSEL_ConfigPin(0,4,2);
PINSEL_ConfigPin(0,5,2);

GPIO_SetDir((4), (1 << 15), GPIO_DIRECTION_OUTPUT);
GPIO_OutputValue((4), (1 << 15), 1);

CAN_Init(CAN_ID_2,500000);
CAN_ModeConfig(CAN_ID_2, CAN_OPERATING_MODE, ENABLE);

CAN_IRQCmd (CAN_ID_2, CANINT_RIE, ENABLE);
NVIC_EnableIRQ (CAN_IRQn);

GUI_Init();


while (1) {
    _DemoScale();

//CAN_SendMsg (CAN_ID_2, &CAN_msg);
//CAN_ReceiveMsg (uint8_t canId, CAN_MSG_Type *CAN_Msg)
        }
}

Is there any thing I should do inside the project to use peripherals? could anyone help me please?

Thank you
Behnam

I'm having the same issue and can't find anything in emWin that would change PIN IOCON settings or interrupt settings for CAN controller.

Hi patrick latimer,

Before answer your question, I was wondering if you can tell which MCU you use and share the simple demo with me, then I can replicate the issue and it can help me to figure out the root cause of the issue.

I'm looking forward to your reply.
Have a great day,
Ping
