AN #107 - Logarithmic bar graph (LED and LCD)

This program is written to create a logarithmic LED/LCD bar graph dB (VU) meter with peak-hold and drop-down. Scale range is 30dB in 3dB steps.
The smart part is that the log conversion is done with the analog comparator on a RC discharge curve.

Ger created two versions : one with an LCD display and one with LED's. The LED version is included here. The LCD version can be downloaded.
