Oscilloscope display

[Art]

Hi Guys,
A little go at making a signal scope display :D

I’m not altogether happy with it, but the poor 16f628A is probably doing a bit much besides drawing.
Cheers, Art.

Ok, fixed the thing, and the line mode is working properly.

I’ll put the code up when I see if I can make it useable in a generic way.
Cheers, Art.

That's pretty cool Art,

Taking "minimalist" to a new high :D

Do you have a specific application you are aiming for?

Hi Heckler, Thanks, yes it’s to modulate the supply of a desktop Tesla coil.
There will be a third relay to set at the taps of a 3 x SLA battery bank so it can change voltage as well,
so there should be a basic sine wave somewhere along the line.
