Hi PCM,
I've just install v5.015 compiler. Result Build Successful
Memory usage: ROM=19% RAM=23% - 30%.
Maybe my compiler v5.008 have some problem.
Thank you very much for your help.

Hi,
This is my application code which I already add the #include usb_bootloader.h.
What and where should I add FUSES to the EX_USB_BOOTLOADER.C file to make it works ?
| Code: |
#include <18F4550.h>
#fuses HSPLL,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,VREGEN
#use delay(clock=48000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7)
#include <string.h>
#include <input.c>
#include <stdio.h>
#include <stdlib.h>
#include <usb_cdc.h>
#include usb_bootloader.h
void main(void)
{
int8 binary_string[10];
char c;
usb_init_cs();
while(TRUE)
{
usb_task();
If(usb_cdc_kbhit())
{
c=usb_cdc_getc();
if (c=='\n') {putc('\r'); putc('\n');}
if (c=='\r') {putc('\r'); putc('\n');}
while(true)
{
printf(usb_cdc_putc,"Enter 8 binary number : \n");
get_string_usb(binary_string,9);
output_D((int8)strtoul(binary_string,0,2));
}
}
}
}

The best way is as follows:
generate your own ex_usb_common.h file that you include in your project directory. Have this contain:
| Code: |
#ifndef __EX_USB_COMMON_H__
#define __EX_USB_COMMON_H__
#include <18F4550.h>
#fuses HSPLL,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,VREGEN
#use delay(clock=48000000)
#define BUTTON_PRESSED() !input(PIN_A4)
#define PIN_USB_SENSE PIN_B2
//Have these to match _your_ input pins.
#define uart_task()
#define HW_INIT()
#define LED_ON(x)
//assuming you don't want an LED
|
Then in your application, have:
| Code: |
#include <18F4550.h>
#fuses none
#use delay(clock=48000000)
#use rs232(baud=9600,UART1, ERRORS)
|
You should _always_ have 'ERRORS' in the RS232 declaration, when using a hardware UART, unless you are adding code to handle errors, so I have corrected this.
Your application code should not have fuses. The bootloader won't load these, and if they did get loaded and differed from the bootloader ones, they could stop the bootloader from running. It's always better that the application that is being loaded by a bootloader, does not setup fuses...
This way the example will compile using your fuse settings and pins only. |

Hi Ttelmah,
Based on the original ex_usb_common.h this line does not include inside. Is it compulsory to include it?
| Code: |
#define USB_HW_CCS_PIC18F4550 //CCS PIC18F4550 USB Development kit
#ifndef __EX_USB_COMMON_H__
#define __EX_USB_COMMON_H__
#if defined(USB_HW_CCS_PIC18F4550)
#include <18F4550.h>
#fuses HSPLL,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,VREGEN
#use delay(clock=48000000)
//leds ordered from bottom to top
#DEFINE LED1 PIN_A5 //green
#define LED2 PIN_B4 //yellow
#define LED3 PIN_B5 //red
#define BUTTON_PRESSED() !input(PIN_A4)
//see section below labeled USB_CABLE_IS_ATTACHED
#define PIN_USB_SENSE PIN_B2
#define HW_ADC_CONFIG ADC_CLOCK_INTERNAL
#define HW_ADC_CHANNEL 0
#define HW_ADC_PORTS AN0
#endif

| The 'common' file is designed to setup the hardware for the test application. It sets up a few things that are not needed at all. Typically the bootloader won't use the ADC, so why set it up?. The example bootloader calls 'HW_INIT'. If you want any special setups for your hardware, add them to this, but otherwise it can just do nothing as I show. |
