Reprap Discount Full Graphics 128×64 LCD Test Sketch

Using Arduino Mega & Ramps

Aşağıdaki Arduino ino sketch kodları kullanarak 12864 tip Reprap Discount Full Graphics 128x64 LCD testi yapabilirsiniz. Kodlar Arduino Mega ve Ramps kartı pin bağlantıları kullanılarak düzenlenmiştir. Farklı bir 3D yazıcı kartı ile de olur, kodlardaki kart pinlerini güncellemeniz gereklidir.

Aşağıdaki kodları ReprapLCDTest.ino şeklinde bir dosyaya kaydedip (veya buraya tıklayıp direk indirebilirsiniz) Arduino ile açın ve bağlantıları yapıp çalıştırın.

//Reprap discount full graphics 128x64 LCD test etmek için kullanabilirsiniz
//Test STOP and Encoder button
//Test buzzer (Hold both STOP and Encoder buttons to activate)
//Test SD detect, disply SD card information
//Test Encode left/right
//Verify the LCD is working.
