Hi,
I have a problem in the usb programmation ,
i had built a program in MiKroC that worked perfectly , but when I try it in ISIS this error message appear : " [PIC18EXEC] PC=0xaA5E . Attempt to execute illegal opcode [loaded from Pc=1A5C]. Instruction executes as a NOP ".
The help menu in MikroC about usb didn't work either ,it shows the same error. i used pic 18f4550
Please help me !!!
 

It could be because of some of header files in Mikroc which are not valid in ISIS or some commands like NOP.
 

My program :
Code:
unsigned char readbuff[64] absolute 0x500;   // Buffers should be in USB RAM, please consult datasheet
unsigned char writebuff[64] absolute 0x540;

char cnt;
char kk;

void interrupt(){
   USB_Interrupt_Proc();                   // USB servicing is done inside the interrupt
}

void main(void){
  ADCON1 |= 0x0F;                         // Configure all ports with analog function as digital
  CMCON  |= 7;                            // Disable comparators

  HID_Enable(&readbuff,&writebuff);       // Enable HID communication

  while(1){
    while(!HID_Read())
      ;

    for(cnt=0;cnt<64;cnt++)
      writebuff[cnt]=readbuff[cnt];

    while(!HID_Write(&writebuff,64))
      ;
  }
}
i configure HID terminal and edit project.
Finally, i have built a program in MiKroC that worked perfectly , but when I try it in ISIS this error message appear : " [PIC18EXEC] PC=0xaA5E . Attempt to execute illegal opcode [loaded from Pc=1A5C]. Instruction executes as a NOP ".
