Tutorial OLED 128x64 dan ATtiny2313 Arduino IDE

ATtiny2313 OLED Kode Program Tampilkan Teks dan Rangkaian - Hari ini saya membagikan kode program untuk mikrokontroller ATtiny2313 untuk dapat menampilkan teks di OLED 128x64.

Jika anda menggunakan library, attiny2313 terlalu kecil memori programnya. Dari itu satu cara adalah tidak menggunakan library, melainkan penulisan kode C secara langsung.

pada Gambar dibawah ini adalah hasil dari kode program yang saya berikan.

ATtiny2313 OLED

Untuk rangkaiannya tidak teralu sulit. Anda dapat melihat pada gambar rangkaian berikut:
