menggunakan-dot-matrix-atmega-dengan-codevision-3

Kali ini kita melanjutkan materi penggunaan dotmatrix pake atmega dengan bantuan IC shift register, dimana untuk teori IC shift register bisa dibaca disini, dengan bantuan shift register kita bisa meng-expand jumlah output ATmega yang digunakan untuk menjalankan kolom milik dot matrix. Shit shift register yang dipakai adalah 74595, boleh pakai varian 74LS595 apa yang lain kalo ada, seterah deh

Programnya lagi2 masih simpel cuma nampilin karakter satu digeser sejauh 10 kolom trus balik lagi dari kolom pertama. Kenapa enggak sekalian yang karakter berjalan??? haha sabar deh masih males2an bikinnya, n sekarang udah akhir semester jadi hahaha berasa males buat ngelanjutin yang berat2 pengen yang having fun wae 😀

Ok deh sementara ini dulu, klo inget besok dilanjutin tutorial dotmatrix nya, pengennya sih untuk dotmatriks minimal sampe 5 chapter, tapi ya sedapetnya ajah #dasarbloggergalau
