USB CDC with PROTEUS and PIC18F4550 problem
PostPosted: Tue Feb 26, 2013 7:01 am     Reply with quote
Hi everyone.
I need to comunicate my PIC with my PC using USB CDC. My program works fine in real world, but I really need to simulate it on PROTEUS, but it doesnt work in simulation. All the samples of proteus works fine, but I think they were written with C18. I install the Virtual USB before the test, but the computer doesnt recognize the "SERIAL DEMO" hardware, and just "UNDEFINED DEVICE", and doesnt install the driver "%CCS%/Drivers".

My code is:
Code:


#include <18F4550.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,VREGEN
#use delay(clock=4000000)

#use rs232(baud=9600, xmit=PIN_C6,rcv=PIN_C7, ERRORS)


#include <usb_cdc.h>


void main(){

   char c;

   //usb_cdc_init();
   //usb_init_cs();
   
   printf("iniciou");
   
   while(1){
     
      usb_task();     // Testa comunicaçao usb
     

      if ( usb_attached() && usb_enumerated() && usb_cdc_connected())
      {
     
         c = usb_cdc_getc();
         printf("%c",c);
     
      }

   }

}




Is the PROTEUS suports the USB SIMULATION with CCS compiler?
Thanks a lot.

this is too easy....

Since your program works fine in a real PIC then the problem you have is with PROTEUS.

You'll have to go to a 'PROTEUS' forum and ask them how to fix PROTEUS as you've proven it is NOT your program or CCS Compiler.
