chào các bạn,
trong proteus 6.9, trong phần "edit component" của pic18f4331, các thiết lập phải viết dưới dạng text. Mình thử mô phỏng tắt sáng led trên chân RB7, mô phỏng trong proteus không chạy, báo lỗi. Mạch thực tế thì chạy tốt. Vậy phải giải quết ra sao
( trong phần "Edit component"
Đoạn code như sau:
#include <18F4331.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
void main(){
set_tris_b(0);
port_b_pullups(FALSE);
setup_power_pwm_pins(PWM_OFF, PWM_OFF, PWM_OFF, PWM_OFF);
delay_ms(1);
output_B(0xff);
while(1){
delay_ms(1000);
output_toggle(PIN_B7);
}
}
mình thiết lập cho 18f4331 như sau:
{PACKAGE=DIL40}
{PRIMITIVE=DIGITAL,PIC18F4331}
{MODDLL=PIC18}
{MODDATA=256,255}
{ITFMOD=PIC}
{PROGRAM=sangled.HEX}
{CLOCK=20MHz}
{CFGWORD=0x3FFB}
{DBG_RANDOM_PMEM=0}
{DBG_RANDOM_DMEM=0}
{DBG_DUMP_CFGWORD=0}
{DBG_STARTUP_DELAY=0}
{DBG_WAKEUP_DELAY=0}
{DBG_ADC_BREAK=0}
{DBG_STACK=1}
{DBG_UNIMPLEMENTED_MEMORY=1}
Lỗi như sau:
