Poor Man's Oscilloscope

[GioppY]

Years ago, Epe Online www.epemag.com published a project "Micro picscope" a simple visual signal monitor.
It shows a representation of the signal waveform using an alfanumeric 16*2 lcd display.
Here a PBP version with PIC16F690

Obviously the performance are very limited; i consider this project a toy.
A graphic area of 8*40 pixels is inadequate to show anything with an acceptable accuracy.
The bandwidth is limited to 4-5KHz
The frequency counter is limited to 6 digit, the precision depends by the internal oscillator frequency.
Despite that, i like it.
Have fun!

I think "I like it" too.

Very cool Gianni!

I'll double. Despite its inaccuracy and little discrimination, is a very good project for begginers.

Really impressive what an alphanumeric LCD can show!

Bravo!

Yup it is really cool. There's a lot of these PIC ppoject here and there, some use GLCD (easy), some use a VB interface (way easier)... the one i prefer, and find the most impressive for a 8 pin device, is the following...
