(still need to update file contents afterward,
but doing it in a separate commit so git can detect renames easier)

to multi-channel, and removed old K9.3 builds which aren't relevant any more,
and old D4Sv2-tintramp builds
|
|
added RGB aux channel modes to models which didn't have it
|
|
|

(also tweaked D4v2 build to match KR4 as much as possible)
(also added Extended Simple UI to Hank's config)

(to show which channel mode is being edited)
also, avoid setting channel mode again if it's not going to change
(this prevents unnecessary flickering)

(also reduced avg standby power by about 15 uA)
(also fixed oscillating voltage mode colors, I think)
The bug happened because sometimes sleep LVP would get triggered, because the
ADC would read zero under some conditions.
This in turn happened because the ADC needs the MCU to be at least partially
awake in order to finish a measurement. So in standby mode, with the MCU only
waking up very briefly to send a sleep tick and go back to sleep, the ADC
required several cycles (like 375ms to 625ms) to finish a single measurement.
This varied depending on how many instructions the MCU executed while it was
awake. In the single-color mode, so few instructions were being executed that
the ADC seemed to time out and abort its measurement, returning a zero. Then a
low voltage warning was sent, which knocked the light back into "Off" mode.
Adding no-op instructions inside the single-color clause was sufficient to
prevent the ADC from timing out, because it kept the MCU awake just barely long
enough. But it was a kludge, and it still took like half a second to finish a
measurement, and the measurements were noisy. It also used more power, because
it required keeping the ADC powered on far too long.
This fix puts the MCU into "ADC Noise Reduction" mode instead, when a voltage
measurement is needed during sleep. It reduces noise to make measurements more
stable... but more importantly, it lets the measurement finish in like 0.5ms
instead of 500ms. So it uses less power and isn't dependent on the number of
calculations the MCU does during each "sleep tick".
As a bonus, this can also measure voltage much more often, while still using
less total energy than before. It was once every 8 seconds, and now it's once
per second.
Avg power use in aux low mode, on a D4Sv2: (avg of 30k samples each)
- before: 101 uA
- after: 86 uA
