18F4331 và modul PWM

[anh_gioi]

em dùng PIC 18F4431 dùng điều xung khai báo như thế này có được ko các bác??

#include "C:\Documents and Settings\anh gioi\Desktop\pic\PIC18F\pwm01\pwm01.h"


void main()
{
int8 i;

setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_INTERNAL|T1_DIV_BY_1);
setup_timer_2(T2_DIV_BY_16,121,1);
setup_ccp1(CCP_PWM);

for(i=0;i<1024;i++)
{
set_pwm1_duty(i);
}
for(i=1023;i>1;i--)
{
set_pwm1_duty(i);
}

}

trong file .h

khi nạp vào thì nó im de.
đây là đoạn mã cho con PIC 16F em cho sang con 18F nhưng nó không chạy.
cho em hỏi tiếp: em muốn dùng tất cả các chân PWM của PIC 18F thì em phải khai báo như thế nào ạ?
(nếu có đoạn code ví dụ thì tốt quá).
thank very much
