| get_float_usb problem |

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. |
