6. VU-meter prototype board dots only & peak hold in the upper 8 steps

VU-meter prototype board dots only & peak hold in the upper 8 steps = regimen 6
24-steps stereo led VU-meter ADC 10 bit (50dB diapasone)
Here in prototype it's realised as:
[-40, -29, -24, -19, -17, -15, -13, -11, -9, -8, -7, -6, -5, -2, -1, 0, +1, +2, +3, +4, +5, +6, +7, +8]
8 regimens of indication, selected with one button repeately depressing
Last regimen stores to ROM automatically
It's possible to preprogram:
every step indication level (common for both channels)
dot hold time
delay after dot hold (before new one peak indicated)
It's possible to preset with analogue components (passive)
rise time
down speed
averaging level
input signal volume
