Design of Portable Digital Oscillograph Based on AVR Single Chip Processor

Gao Wei-xi

Abstract

An implementation scheme of portable digital oscillograph based on AVR mcu was presented in the paper. This scheme integrates the variable gain control,high-speed data acquisition,I2C bus,USB communication,LCD control and display,AVR MCU CO from processing technology,finally was realized with LCD display and waveform analysis function. The experiment has achieved good results,and has a certain promotion value.
