找到問題了
void _ISR _C1Interrupt(void) { if(CAN1IsRXReady(0)) { CAN1ReceiveMessage( RxData,4,0 ) ; // Receive 8 bytes from Buffer 0 C1RX0CONbits.RXFUL = 0 ; } C1INTFbits.RX0IF=0;//清除中斷旗標 ***加入此行就可以了 IFS1bits.C1IF = 0; //清除中斷旗標 }

可以使用CAN Library 所提供的 marco 來啟動及關閉 CANx 的中斷。
Macro
資料在 : C:\Program Files\Microchip\MPLAB C30\docs\periph_lib\dsPIC30F_CAN_Library_Help.htm

請問CAN Module 的收發使用中斷模式要如何設定??

CAN Module 的收發都可以使用中斷模式處理的，只是 Microchip 所提共的範例是以Polling的方式為主，這樣做主要是讓程式更簡單對初學者而言比較容易瞭解程式的動作。

請教客位前輩，CAN的這個部份可以使用中斷的方式進行資料的讀取嗎，還是只能用等的，還有就是，MICROCHIP有提供類似的範例程式嗎？
