Low cost PC-based quad channel real-time / storage oscilloscope with PIC16F877

[zokij]

  I found this project on the net... 

I hope that for someone will be nice and usefull   

designed by Colin McCord

you can use schematisc , source code, win application ....

  One more 


October 2000 of EPE magazine, Dual Channel Virtual Scope, using PIC 16F877 and a static RAM 6264. It stores the samples in the RAM and transfers to a PC where a software plots the signal.


There are other similar projects you can find in the EPEs: April 2000 - Micropicscope (rudimentar scope using simple 16x2 LCD) and a May 2001 - PIC Graphics LCD scope.

nice work

[dulce_antunes]

Some time ago i wanted to develope such an oscilloscope with internal storage, but
i have it paused
Does somebody wants to start with me?

I have a question about all this projects.......

The response time (A/D conversion time for pics and avrs) is too slow for high frecuencies?. It means that in high frecuencies (>100kHz) the graphic waveform will be not accurate?.

I calculate this with the A/D response time given for PIC16F877
