AN3034SW Error C2801 missing ';'

rachelsanford — Sun, 14 Aug 2016 21:10:14 GMT

I'm trying to run the sample code from document AN3034 "Using MSCAN on the HCS12 Family". The code is in document AN3034SW. Both of these documents are provided by NXP.

I did modify an include statement and the pragma Link_Info so that it matched the development board I am working with, the MC9S12DG256 development board.

I tried to compile the code and I am getting "Error C2801 ';' missing", but it seems like I have all of the appropriate semicolons. It is also strange because the error happens on 4 very similar lines of code. It is during the CANInit function that this occurs. The CANInit function is shown below. The full code is attached. The code that I copied and minimally modified is from AN3034SW. The lines causing errors are in RED. They all cause the same error: "Error C2801 ';' missing". I am using CodeWarrior 5.9.0.

//CANInit Function

void CANInit(void){

CAN0CTL0 = 0x01; //Enter initialization mode

while(!(CAN0CTL1&0x01)){}; //Wait for initialization mode ACK

CAN0CTL1 = 0xA0; //Enable MSCAN module and Loopback Mode

CAN0BTR0 = 0xC7; //Synch Jump = 3Tq clock cycles (re calculate?)

CAN0BTR1 = 0x3A; //Set number of samples per bit, TSEG1 and TSEG2

CAN0IDAC = 0x10; //set four 16-bit filters

//Acceptance Filters

CAN0IDAR0 = ACC_CODE_ID100_HIGH; //16-bit filter 0

CAN0IDMR0 = MASK_CODE_ST_ID_HIGH; //Accepts Standard Data Frame Msg ERROR Missing ;?

CAN0IDAR1 = ACC_CODE_ID100_LOW; //with ID 0x100

CAN0IDMR1 = MASK_CODE_ST_ID_LOW;

CAN0IDAC = 0x10; //Not sure why this is twice in code

CAN0IDAR2 = 0x00; //16-bit filter 1

CAN0IDMR2 = MASK_CODE_ST_ID_HIGH; //Accepts standard Data frame msg

CAN0IDAR3 = 0x00; //with ID 0x000

CAN0IDMR3 = MASK_CODE_ST_ID_LOW;

CAN0IDAR4 = 0x00; //16-bit filter 2

CAN0IDMR4 = MASK_CODE_ST_ID_HIGH; //Accepts standard Data frame msg

CAN0IDAR5 = 0x00; //with ID 0x000

CAN0IDMR5 = MASK_CODE_ST_ID_LOW;

CAN0IDAR6 = 0x00; //16-bit filter 3

CAN0IDMR6 = MASK_CODE_ST_ID_HIGH; //Accepts standard Data frame msg

CAN0IDAR7 = 0x00; //with ID 0x000

CAN0IDMR7 = MASK_CODE_ST_ID_LOW;

CAN0CTL0 = 0x00; //Exit initialization mode request

while((CAN0CTL1&0x01)!=0){}; //Wait for normal mode

} //end void CANInit
