This portable Oscilloscope project uses Graphical LCD screen, 64*128 pixel dots (GDM12864A with KS0108 processor or other compatible) as display and Microcontroller ATMEGA32 as the processor. The project used an external ADC0820 converter chip to increase the speed.

This Minimalist Oscilloscope project built using Nokia 5165 LCD and PicAxe 08M microcontroller. The scope will wait for a trigger at half the peak to peak of the signal on the rising-edge, takes 42 measurements of that signal, store it internally and display results on LCD screen.

B+K Precision’s model 2120B is a dual trace oscilloscope that offers high performance. This unit is great for the hobbyist or student that really needs an oscilloscope. It has all the standard features of an analog scope and has worked very well for simple tasks. However, if you need any complex measurements or functions, [...]

Commonly, electronic hobbyist use LDC or 7 segments or LED as display for their digital clock project. But Emilio has designed unique digital clock which the output displayed to Oscilloscope. It’s interesting electronic project, since oscilloscope used for analysis electronic signal both analog and digital. The project uses microcontroller AVR ATtiny 2313 as main processor [...]

Let’s build a simple digital oscilloscope.

Single channel 100MHz/100MSPS (100 mega-samples-per-second)
RS-232 based (we’ll look into USB too)
Inexpensive!

A simple digital oscilloscope recipe

by Vassilis Serasidis

This is one of great project based on AVR microcontroller. It use ATmega 32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) [...]

Project description:
We chose to construct a digital oscilloscope as our final project for this course. The skills involved in this project proved a natural extension of some of the topics we covered in class. We were able to learn more about the UART, AD sampling, memory indexing, keypad usage and many other topics [...]
