* went back to continuous lowpass because it had the best noise reductionSelene ToyKeeper2020-02-282-52/+74
| | | | | (also, now treating smoothed ADC values as 11-bit, with the lowest 5 bits chopped off to eliminate noise)
* brute force method for reducing ADC noise -- average a ridiculous number of ↵Selene ToyKeeper2020-02-052-20/+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.
* still doesn't work, but at least it's a bit less broken than before...Selene ToyKeeper2020-02-051-8/+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)
* first pass at a smaller simpler thermal regulation algorithm...Selene ToyKeeper2020-02-051-75/+52
| | | | ... doesn't work well, but I'm saving it so I can experiment with other methods and maybe revert back later.

* saving state of ADC / WDT refactoring before doing more changes... what ↵Selene ToyKeeper2020-01-305-76/+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

* | | merged irq-refactor branch, which fixes some small but long-standing issues:Selene ToyKeeper2019-11-1916-310/+399
|\| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - fixed occasional short/aborted frames in aux LED sleep animation - fixed rare case of bogus voltage and/or temperature values - fixed issue where nice_delay_ms() didn't work in setup() - fixed theoretical possibility of extra-noisy buttons causing a hang - fixed reboot loop which happened after any crashes - fixed issue where button press in sleep mode could occasionally crash (but the issue may have been created by this branch before being fixed by it) - reduced occasional missed button events while asleep (still seems to happen but not nearly as much) Also does some other things: - cleans up the ADC code significantly - cleans up the WDT code - adds a voltage stabilizer/lowpass option (enabled on t1634 builds) - greatly reduces time spent per interrupt, which might make a future PWM-DSM technique possible - moves most interrupt-handling logic to a non-critical code path, deferring that code until timing doesn't matter as much - sped up button state measurements - very slightly reduces power used in sleep mode

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.
