Title: Pic based waveform capturing and restoring
Post by: shibuv on July 22, 2009, 01:16:04 13:16
hello

anybody can help me to find a project for storing and reproducing waveforms from a function generator using PIC16f877A.

Hi,

i don't know if this can help you ,i made project with AD9833 from Analog Devices,This  component Can Generate Sine,Square,Triangle up to 10 MHZ (20 i think).

I made it with Pic877 and programmed in basic(Test Board).i can upload pcd,.bas etc if you need. i don't have any schematic,i've build this on the fly.

I would check out some old issues of EPE where they did some pc scopes and Function generators cause they used an 877 and they had store the wave before showing it on the pc if I remember right.
Don't remember the exact issue's but try this link

Hi Digibob,

Please can you unload your code?

No Problem,Proton Basic code And Major Part Of Code was Copied From Other Site.it's for use with AD9833
