Mic to Vga Demo Update

Reinhard

I have update my mic to vga demo:
The screen is refreshed cyclically.
A dotted zero line is output.
Every 2 seconds you switch between DC coupling and AC coupling.
The gain at AC is greater.
The AC coupling is realized with an IIR high pass.

The sound come from a pc (tone generator) over the air.
