Digital oscilloscope GLCD using Atmega32 microcontroller

AVR ATmega Projects, Metering - Instrument Projects / Ibrar Ayyub

This project describes how to make a digital oscilloscope using an Atmega32 microcontroller and a graphics LCD. The GLCD used has 64*128 pixel dots (GDM12864A with KS0108 processor) and the AVR runs at 16 MHz using an external crystal oscillator. To enhance the speed further, it uses an external A/D converter chip, ADC0820. The sampling
