16-bit numbers
2020-03-16deleted commented-out WDT code from previous revisionSelene ToyKeeper1-7/+0
(had only saved it so there would be a note in history about why it's gone)
2020-03-16cleaned up WDT ADC timer code slightly, and removed a bit of redundant codeSelene ToyKeeper1-6/+8
2020-03-16reduced regulation jitter by biasing errors toward zero by a constant amount,Selene ToyKeeper1-1/+14
which mostly impacts small errors (and reduces jitter during the flat phase of regulation) while leaving large errors pretty much unaffected... also, made acceptable thermal window smaller to make up for this new extra tolerance
2020-03-15the ADC sample count doesn't need to be 16-bit any more, and isn't really a ↵Selene ToyKeeper2-3/+4
count any more... ... just a boolean flag for whether this is the first sample or a later sample (so I changed it and reduced the ROM size by ~28 bytes)
2020-03-15removed dead comments and dead codeSelene ToyKeeper1-28/+2
2020-03-15replaced temperature_timer (which wasn't even being used) with a variable ↵Selene ToyKeeper1-27/+43
delay between warnings, so large warnings can remain frequent while small warnings are separated by more time, based on a cumulative error counter which must pass a threshold before the next warning is sent (this is producing good test results so far on D4v2 and D4Sv2)
2020-03-13tried to make thermal code a bit less twitchy...Selene ToyKeeper3-13/+19
it regulates really fast on D4, but once it's stable, the adjustments are too large
2020-02-28went back to continuous lowpass because it had the best noise reductionSelene ToyKeeper2-52/+74
(also, now treating smoothed ADC values as 11-bit, with the lowest 5 bits chopped off to eliminate noise)
2020-02-05brute force method for reducing ADC noise -- average a ridiculous number of ↵Selene ToyKeeper2-20/+14
samples (because, for some reason, even though 64 samples is plenty in a test program, it ends up being extremely erratic when used inside Anduril... and I'm not sure why) also, use 15-bit ADC values instead of 16 bits, in the temperature logic (to help protect against integer overflows) ... but this code still doesn't work well. It regulates down *very* fast, and then gradually rises until the next extra-fast drop-down. :( ... also, tempcheck mode sometimes changes by 4-5 C between readouts, which is worrisome. ... and factory reset is still broken.
2020-02-05still doesn't work, but at least it's a bit less broken than before...Selene ToyKeeper1-8/+12
(ceiling value was all wrong, and the response magnitude was way too big) (also, temperatures here are unsigned, since freezing is about 270 in ADC units)
2020-02-05first pass at a smaller simpler thermal regulation algorithm...Selene ToyKeeper1-75/+52
... doesn't work well, but I'm saving it so I can experiment with other methods and maybe revert back later.
2020-02-05replaced Anduril's gradual adjustment speed code with a smaller simpler versionSelene ToyKeeper1-43/+17
2020-01-30saving state of ADC / WDT refactoring before doing more changes... what ↵Selene ToyKeeper5-76/+59
changed so far: - removed LVP lowpass and thermal regulation lowpass logic; it's probably redundant now - slowed ADC deferred logic timing to 4X per second instead of 16X, because there doesn't seem to be much reason to do it any faster - reduced thermal event rate-limit to just 1 second, for more responsive regulation - added "EV_temperature_okay" signal, to help stop adjustments at an appropriate time instead of going to far - sped up sleep LVP to one measurement every 8 seconds instead of 16, to help the aux LEDs respond to voltage changes faster (effect on standby time is negligible) - make sure the WDT doesn't set the ADC channel or counter... except in standby mode
2020-01-30switched to a pseudo-rolling-average method to reduce noise, set prescaler ↵Selene ToyKeeper1-8/+13
back to 64
2020-01-29increased effective ADC resolution by switching from continuous-lowpass to ↵Selene ToyKeeper1-64/+43
sum-of-discrete-window method
2020-01-29remove truncation noise by adding 0.5 to each resultSelene ToyKeeper1-24/+22
(keeps stable values within ~0.46 to ~0.54 range, so truncated result has no noise)
2020-01-29rewrote ADC code to use a continuous lowpass system on all measurements, to ↵Selene ToyKeeper5-130/+194
eliminate noise and maybe increase precision (thermal code still needs to be rewritten though)
2019-12-17fixed too-slow thermal response (was introduced in the irq-refactor branch)Selene ToyKeeper1-5/+8
2019-12-11added support for Fireflies ROT66 G2 and PL47 G2Selene ToyKeeper2-0/+109
2019-12-04added a compile-time flag to enable/disable momentary mode (suggested by Agro)Selene ToyKeeper1-1/+18
2019-12-04fixed compile errors to handle a couple USE_ flags better:Selene ToyKeeper1-2/+8

of the previous attempt
2019-11-29adjusted BLF Lantern (Sofirn LT1) tint ramping power correction factor to ↵Selene ToyKeeper2-1/+8
match production units (also made the factor configurable per build target)
2019-11-24enabled muggle mode again in all build targets, since it fits nowSelene ToyKeeper4-23/+0
2019-11-20fixed unintentional wakeup right after going to sleepSelene ToyKeeper1-2/+2
(by enabling the PCINT slightly sooner, before setting its "handled" flag)
2019-11-19Mateminco MF01S can fit muggle mode again, barelySelene ToyKeeper1-3/+3
2019-11-19reduced build size by a few bytesSelene ToyKeeper2-3/+3
2019-11-19the Q8 can just barely fit muggle mode againSelene ToyKeeper1-3/+3
2019-11-19enabled prevent_reboot_loop() on all builds, to reduce the impact of any ↵Selene ToyKeeper1-5/+7
potential crashes (even though I just fixed the only known bug which could trigger an unintentional reboot)
2019-11-19fixed ADC cycles running 2X as fast as intendedSelene ToyKeeper1-8/+8
2019-11-19cleaned up WDT code a bit, reduced total size,Selene ToyKeeper2-29/+25
fixed bug where ticks_since_last could have the wrong value sometimes, reduced power use in sleep mode very slightly by skipping button-handling code while asleep
2019-11-18fixed issue where button-press-during-sleep could occasionally cause a rebootSelene ToyKeeper1-3/+7
(by turning off PCINT when the light is awake)
2019-11-18added SOS mode to the BLF LT1 Lantern build, because people wanted itSelene ToyKeeper2-7/+44
2019-11-14turned off muggle mode on Q8 and MF01S, to make builds small enough againSelene ToyKeeper2-0/+11
2019-11-14oops, put voltage lowpass on the wrong D4SSelene ToyKeeper2-3/+4
2019-11-14added a lowpass filter for battery voltage measurementsSelene ToyKeeper3-37/+29
(but only on attiny1634 devices, since it costs a bit of space and isn't strictly necessary)
2019-11-14fixed factory reset (wasn't running interrupt logic since it's deferred now)Selene ToyKeeper3-12/+11
(also fixed issue where nice_delay_ms() was aborted during setup()) (and adjusted the timing to make factory reset similar to the speed it was before this change)
2019-11-14fixed ADC code; measures and behaves correctly now, and is easier to read...Selene ToyKeeper3-41/+41
... but factory reset's auto-calibrate still doesn't get the right values for some reason (manual calibration works, but not auto)
2019-11-14started refactoring ADC code to split voltage and temperature into their own ↵Selene ToyKeeper2-212/+226
functions
2019-11-14refactored how interrupts work...Selene ToyKeeper10-38/+108
set a flag and return immediately, then handle the actual logic later during a less-critical code path Enables smarter responses to standby wakeups. Seems to fix missed button presses during standby, and most of the too-fast sleep ticks. Also eliminated waits from button state measurement, so it can happen easier during standby. (also eliminates the chance of an infinite loop on extra-noisy hardware) Also might improve timing-sensitive interrupts like attiny85 PWM channel 4, or a PWM-DSM hybrid technique I'd like to try. BUT this change also appears to break the thermal sensor, so that needs to be fixed.
2019-11-13fixed some compile issues related to delay_4ms()Selene ToyKeeper3-2/+2
2019-10-02made lantern's muggle mode brighter (matches default stepped ramp level 4 of 5)Selene ToyKeeper1-0/+3
and made the floor slightly lower (almost as low as level 1 of 5) because this light doesn't run hot enough for the previous limit to make sense (was roughly step 2.9 of 5)
2019-10-02added a default version.h for people who don't use the build scriptSelene ToyKeeper1-0/+4
2019-09-28after safety ramp-down, if the button remains stuck, lock the lightSelene ToyKeeper1-1/+9
2019-09-24added a version check function on 15+ clicks from off, added a safety ↵Selene ToyKeeper4-0/+52
ramp-down if button is held too long at ceiling (also removed muggle mode from a couple build targets because it doesn't fit, not enough ROM)
2019-09-24sped up blink_digit() a little bit, because it was annoyingly slowSelene ToyKeeper1-3/+4
2019-09-24made the maximum number of clicks 15 instead of 14Selene ToyKeeper1-1/+1
