• Untuk LED ANODA : Logika 0 = led menyala

Logika 1 = led mati

• Untuk LED KATODA : Logika 0 = led mati

Logika 1 = led menyala

•Delay = tunda

• Penundaan terhadap kinerja mikrokontroler

•DELAY

Published By Stefanikha69

• Menghasilkan delay dalam program-C berada pada header delay.h yang harus dimasukan (include) sebelum digunakan.

• Sebelum memanggil fungsi, interupsi harus dimatikan terlebih dahulu, apabila tidak maka delay akan lebih lama dari yang diharapkan. Juga sangat penting untuk menyebutkan frekuensi clock chip IC AVR yang digunakan pada menu Project – configure - C compiler - Code Generation.

• Header delay#include <delay.h>

• Perintah delay

delay_ms(------);

Waktu tunda dalam milidetik:Misalkan:delay_ms(1000); berarti ditunda selama 1 detik

•CODE PROGRAM• Untuk menyalakan led bergantian misalkan pada posisi PORTC.0,

PORTC.1 dan PORTC.2 dengan masing-masing waktu tunda selama 1 detik. (jadi waktu keseluruhan yang dibutuhkan sistem yaitu 3 detik)

while(1){

PORTC=0b11111110;Delay_ms(1000);PORTC=0b11111101;Delay_ms(1000);PORTC=0b11111011;Delay_ms(1000);
