Urgent!! facing problem PIC 18f2550
PostPosted: Tue May 26, 2009 2:13 am     Reply with quote
Can anyone check for me the code below:
Code:
#include <18F2550.h>
#fuses HSPLL,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL3,CPUDIV1,VREGEN
#use delay(clock=48000000)
#define USB_HID_DEVICE     FALSE             
#define USB_EP1_TX_ENABLE  USB_ENABLE_BULK   
#define USB_EP1_RX_ENABLE  USB_ENABLE_BULK   
#define USB_EP1_TX_SIZE    1                 
#define USB_EP1_RX_SIZE    3                 
#include <pic18_usb.h>     
#include <PicUSB.h>       
#include <usb.c>           
#define LEDV    PIN_B6
#define LEDR    PIN_B7
#define LED_ON  output_high
#define LED_OFF output_low

#define modo      recibe[0]
#define param1    recibe[1]
#define param2    recibe[2]
#define resultado envia[0]


void main(void) {

   int8 recibe[3];
   int8 envia[1];
   LED_OFF(LEDV);                 
   LED_ON(LEDR);
   usb_init();
   usb_task();                     
   usb_wait_for_enumeration();     
  // LED_ON(PIN_A0); 
   LED_OFF(LEDR);
   LED_ON(LEDV);                   
   SET_TRIS_A( 0xFF);
// LED_ON(PIN_B0);
  while (TRUE)
   {
      if(usb_enumerated())         
      {
        if (usb_kbhit(1))         
         {
              usb_get_packet(1, recibe, 3);
           
            if (modo == 0 || modo == 1)
            {
             if (INPUT_STATE(PIN_A1)& INPUT_STATE(PIN_A2))
            { 
               resultado =3; 
               usb_put_packet(1, envia, 1, USB_DTS_TOGGLE);
             
             }
             if (!INPUT_STATE(PIN_A1) & INPUT_STATE(PIN_A2))
             {
             resultado =2;

               usb_put_packet(1, envia, 1, USB_DTS_TOGGLE);
            }

           
         }
      }
   }
}
}
//modo == 0 || modo == 1

#include <E:\car project\USB Interface\USB\CCS\PicUSB.h>

void main()
{
   int8 receivedPacket[2];
   output_B (0x80);
   usb_init();
   usb_task();
   usb_wait_for_enumeration();
   output_B (0x40);

   while (TRUE)
   {
     if (usb_enumerated())
      {
         if (usb_kbhit(1))
            {
               usb_get_packet(1,receivedPacket,2);
               switch(receivedPacket[0])
               {
                case 0x00;
                output_B(0xff);
                break;

                case 0x01;
                output_B(0x00);
                break;
                }
            }
       }
     }
}
It is about usb microcontroller.
URGENT!! Thanks

You mean aside from the fact it has two "main" routines, and can never work therefore.....

No, I don't think you do see. This forum is composed of volunteers. The way to get volunteers to help you is to make it as easy as possible for them to help you. That means doing as much of the work yourself first. You can't expect someone else to spend time analyzing your code if you are not willing to spend the time yourself. Say what you think the code ought to do. Say what steps you have already taken to verify whether it is doing it or not. Say what you observed the code to do in testing. If you are not willing to do these things, no one is going to bother trying to help you.

Okay, sorry for that, I will try to solve it by myself. Thanks anyway. Smile

However my basic comment, should be your starting point. One 'main' only. At the moment, nobody looking at your code, could even begin to work out what would actually happen...
