Implement generalized analog input module

[xs5871]

Draft of a better analog input module as mentioned in #638.

[piman13]

so AnalogIn is being imported twice in this exsample
I think its suppose to be from kmk.modules.analogin import AnalogInput, AnalogKey

import board
from analogio import AnalogIn
from kmk.modules.analogin import AnalogIn

Other note where is this suppose to be placed
or is this my lack of understanding of kmk

you import the stuff above in code.py
but KC is not avable in code.py
putting it in keymap.py would make sense so are the imports suppose to be there as well?

analog = AnalogIn(
    [
        AnalogInput(AnalogIn(board.A0)),
        AnalogInput(AnalogIn(board.A1)),
        AnalogInput(AnalogIn(board.A2)),
    ],
    [
        [AnalogKey(KC.X), AnalogKey(KC.Y), AnalogKey(KC.Z)],
        [KC.TRNS, KC.NO, AnalogKey(KC.W, threshold=96)],
    ],
)

keyboard.modules.append(analog)

[piman13]

oh and is the analog = AnalogIn suppose to be AnalogInputs as well?

analog = AnalogIn(
    [
        AnalogInput(AnalogIn(board.A0)),
        AnalogInput(AnalogIn(board.A1)),
        AnalogInput(AnalogIn(board.A2)),
    ],
    [
        [AnalogKey(KC.X), AnalogKey(KC.Y), AnalogKey(KC.Z)],
        [KC.TRNS, KC.NO, AnalogKey(KC.W, threshold=96)],
    ],
)

edit "AnalogInputs" not AnalogInput

[piman13]

also a minimum change for on_change needs to be added either as a override-able value or just a 1 or 2% min-max (pots like to float a little and hopping between 1-10 units all the time keeps triggering it

[piman13]

question... I've added pulls to the analogin branch does this need redone or if you merge it it will the draft update?
other note. so much better to work with compared to potentiometer.py and I'm working on example code for calling midi to set the volume of stuff on the computer

Now is there any good way to pass a int to this so we don't have to copy pasta what is effectively the same code
Something like SDL(0)

SLD0 = AnalogEvent(
    on_change=lambda self, event, keyboard : KC.MIDI_CC(7, event.value, channel=0).on_press(keyboard),
)
SLD1 = AnalogEvent(
    on_change=lambda self, event, keyboard : KC.MIDI_CC(7, event.value, channel=1).on_press(keyboard),
)
SLD2 = AnalogEvent(
    on_change=lambda self, event, keyboard : KC.MIDI_CC(7, event.value, channel=2).on_press(keyboard),
)
SLD3 = AnalogEvent(
    on_change=lambda self, event, keyboard : KC.MIDI_CC(7, event.value, channel=3).on_press(keyboard),
)

I had to change all the names midway through, because I didn't notice that CP already uses the name analogin.
Docs are fixed now

Yes, you have to import KC. The docs show examples, they don't spell out a complete configuration.

1. That's what the filter argument is for.
2. The default filter already downscales to 8bit. Most MCUs have 12bit ADC, so that's a noise reduction factor of 16. In my experience that is enough in pretty much any reasonably designed circuit. If your ADC measurements still vary by 10 units, then that is definitely a hardware/design issue. Check your ADCs input impedance requirements.

Why use midi keys in the first place? Just use the midi API directly.
