try to read
topic on this forum...
there are plentiful of project for PC Oscilloscope ...
but you will learn to use forum as well ...
in meantime here is one project for you ...
Here are the basic specs :
* 5MHz analog bandwidth (*see below)
* Dual channels
* Optional external trigger input.
* PC-Based, connects to standard parallel port.
* Easy to build on one single sided pcb.
* Vertical position adjustments.
* Fully software controlled timebase and attenuation rages.
* 100ns/div to 50ms/div timebase in 1-2-5 sequence.
* 100mV/div to 5V/div vertical ranges in 1-2-5 sequence.
or for me easy (better) one:PIC12F675 OscilloscopeThis is a simple PC voltage oscilloscope using only a PIC12F675, a 20MHz oscillator, and a RS232 level shifter. The PIC takes a sample on GP2, immediately sends it to the PC at 115,200 baud using an software asynchronous serial routine, and repeats. It sends a 8-bit value that is read by the Visual Basic software and displayed on the screen (see examples below). The Visual Basic software deduces the time period between submissions and adjusts the display accordingly.The microcontroller code can be downloaded here:jal: http://semifluid.com/PIC12F675_Oscilloscope/uSendAnalogHS.jalhex:http://semifluid.com/PIC12F675_Oscilloscope/uSendAnalogHS.hexVisual Basic code example:http://semifluid.com/PIC12F675_Oscilloscope/675OscilloscopeDR1r1.zipTHANK'S zokij NICE TRY BUT YOU HAVE TO BUY PARTS SO IT ISN'T FREE Posted on: May 12, 2008, 06:30:05 18:30 - Automerged
Ok, my mistake
Then you can try :
The PC Scope project was published on Everyday Practical Electronics on August 2007 and September 2007V2 PC scope
PC controlled PIC sampling
Frequency range DC to >40kHz
Dual channel analogue
Single channel spectrum analysis
Single channel 8-bit digital
On-screen control of all functionsI hope now is ok bbarney wise guy
