Nokia 3510i lcd (S1D15G14) arayüz hitech pic16f628

Epson S1D15G14 entegresini kullanan Nokia 3510i grafik lcd kullanımı için hazırlanmış bir devre projenin yazılımı Hi-tech C ile hazırlanmış mikro denetleyici ise pic16f628.

This example shows how the Nokia 3510i color LCD can be interfaced and driven using the PIC16F628 microcontroller. The code is written in Hi-Tech C.The Nokia LCD has 96×65 pixels. Software : This project uses Hi-Tech C compiler available from www.htsoft.com . I used Ic-prog to program the 16F628 using the ProPic-2 Programmer
