my xtal is 20 MHz
help me plzzz
thank you very much

#include <18F86j50.h>
#fuses HSPLL,PLL5,NOWDT,NOPROTECT,NOCPUDIV
#use delay(clock=48000000)
#include <pic18_usb.h>
#include <usb_desc_mouse.h>
#include <USB.c>
#byte OSCTUNE = 0xF9B
#bit PLLEN = OSCTUNE.6
void main(void) {
PLLEN = 1;
delay_ms(10);
#define MOUSE_SEQUENCE_STEPS 16
const char mouse_seq[MOUSE_SEQUENCE_STEPS]=
{0, 1, 3, 4, 4, 4, 3, 1, 0, -1, -3, -4, -4, -4, -3, -1};
int8 out_data[4];
unsigned int8 x_seq=0; unsigned int8 y_seq=MOUSE_SEQUENCE_STEPS/4;
unsigned int8 count=0;
usb_init_cs();
while (TRUE) {
usb_task();
if (usb_enumerated()) {
out_data[0]=0; //button state goes here
out_data[1]=mouse_seq[x_seq];
out_data[2]=mouse_seq[y_seq];
out_data[3]=0; //wheel state goes here
if (usb_put_packet(1,out_data,4,USB_DTS_TOGGLE))
count++;
if (count > 10) {
if (++x_seq>=MOUSE_SEQUENCE_STEPS) {x_seq=0;}
if (++y_seq>=MOUSE_SEQUENCE_STEPS) {y_seq=0;}
count=0;
}
delay_ms(10);
}
}

Get both datasheets and compare what is different about the two devices.
Have you got the 'Hello World' and 'blinking LED' programs to run on the 2nd device ?
As for the message, if that's from a PC running Windows, odds are you didn't load whatever driver is necessary for the OS to recognize the 'new' USB device( the PIC). |
