get_float_usb problem
PostPosted: Wed Feb 24, 2010 3:01 pm     Reply with quote
Hi,

I have this little program to test how to write strings using USB, I used to use a similar one in RS232, but now, i am trying to change everything for USB.

Ok, my problem is when I compile the error is "function used but not defined", but its defined in the included file usb_cdc.h

the code:

Code:

#include <18F4550.h>
#fuses HSPLL,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,VREGEN
#use delay(clock=48000000)

#include ".\include\usb_cdc.h"
#include <stdlib.h>

float reference=0;

// ==
void get_info(void){
   printf(usb_cdc_putc,"\fNumber: ");
   reference = get_float_usb();
   printf(usb_cdc_putc,"\fNumber: %6.2f",reference);
   delay_ms(50);
} // end get_info();

// ==
void main(void){
   delay_ms(300);
   usb_cdc_init();
   usb_init();
   while(!usb_cdc_connected()) {}
   do {
      usb_task();
      get_info();
   }
while(true);

}


I have a PIC18F4550 and version 3.245.

Thanks

I solved.

the problem is that first i have to include stdlib.h instead of usb_cdc:

Code:

#include <stdlib.h>
#include ".\include\usb_cdc.h"


I didnt know that, I am new in CCS, notwithstanding, I have some experience in PIC.

Thanks.
