 Grin One more  Roll Eyes


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.

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
