Arduino-128x64-graphic-display

Ko'p uchraydigan savol 12864a displey arduinoda qanday ishlaydi?

Arduino C++ muhitida quyida 128x64 grafik displey uchun dasturiy vosita rivojlantirilgan.

Bu haqda to'liq ma'lumot berib o'taman.

U8G2 va U8G kutubxonalari.

Foydalanishda quyidagilar bajariladi:

• Ulanish sxemasidan foydalanish
• Dasturdan foydalanish

Rasmda ko'rinishidan bir xil lekin, ishlash prinsipi 2 xil bo'lgan displey ko'rsatilgan.

• Birinchi turdagi displey 128x64 o'lchamdagi KS0108.
• Ikkinchi turdagi displey 128x64 o'lchamdagi ST7920.

Birinchi turdagi displey arxitektura jixatdan ancha eski hisoblanadi va I/O port orqali sahifalardagi pixel qiymatlarini boshqarish protokolini qo'llab quvvatlaydi ammo SPI (Serial Peripheral Interface) qo'llab bo'lmaydi. Ikkinchi turdagi displey esa yangilangan versiya hisoblanadi va I/O port orqali hamda SPI orqali boshqarish imkoniyati mavjud.

Ulanish sxemasi:

Quyida 2 xil turdagi displeylarning ulanishi keltirilgan:

KS0108 displeyning Arduino Uno qurilmasiga ulanishi:

ST7920 displeyning Arduino Uno qurilmasiga ulanishi:

Dastur:

Dasturdan foydalanishda quyidagi o'zgartirishlar bajariladi:

#Arduino code
