* Add ARRAY_SIZE and CEILING utility macros
* Apply a coccinelle patch to use ARRAY_SIZE
* fix up some straggling items
* Fix 'make test:secure'
* Enhance ARRAY_SIZE macro to reject acting on pointers
The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.
* explicitly get definition of ARRAY_SIZE
* Convert to ARRAY_SIZE when const is involved
The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
@ rule6a using "empty.iso" @
type T;
const T[] E;
@@
- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```
* New instances of ARRAY_SIZE added since initial spatch run
* Use `ARRAY_SIZE` in docs (found by grep)
* Manually use ARRAY_SIZE
hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers
* Just like char, sizeof(uint8_t) is guaranteed to be 1
This is at least true on any plausible system where qmk is actually used.
Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

* Made static backlight pwm resolution configurable
* Made breathing backlighting configurable too
* Finished my ifdef
* Ran clang-format
* Added missing semi-colon
* Solved weird behaviour by right-shifting the right amount
* Made breathing period scaled on actual pwm frequency
* Made the low end deadzone scaled on the top value
* Moved 'pwm_frequency' declaration outside ifdef
* Fixed 'never used' error
* Fixed 'never used' error
* Fixed breathing ISR to 120Hz
* Removed pwm_frequency constant
Constant is no longer needed since running the breathing ISR at a fixed 120Hz
* Re-add brightness limiting
* re-introduce scaling

* Add Per Key functionality for AutoShift (#11536)
* LED Matrix: Reactive effect buffers & advanced indicators (#12588)
* [Keyboard] kint36: switch to sym_eager_pk debouncing (#12626)
* [Keyboard] kint2pp: reduce input latency by ≈10ms (#12625)

* [CI] Format code according to conventions (#12650)
* feat: infinite timeout for leader key (#6580)
* feat: implement leader_no_timeout logic
* docs(leader_key): infinite leader timeout docs
* Format code according to conventions (#12680)
* Update ADC driver for STM32F1xx, STM32F3xx, STM32F4xx (#12403)
* Fix default ADC_RESOLUTION for ADCv3 (and ADCv4)
Recent ChibiOS update removed ADC_CFGR1_RES_10BIT from the ADCv3 headers
(that macro should not have been there, because ADCv3 has CFGR instead of
CFGR1). Fix the default value for ADC_RESOLUTION to use ADC_CFGR_RES_10BITS
if it is defined (that name is used for ADCv3 and ADCv4).
* Update ADC docs to match the actually used resolution
ADC driver for ChibiOS actually uses the 10-bit resolution by default
(probably to match AVR); fix the documentation accordingly. Also add
both ADC_CFGR_RES_10BITS and ADC_CFGR1_RES_10BIT constants (these names
differ according to the ADC implementation in the particular MCU).
* Fix pinToMux() for B12 and B13 on STM32F3xx
Testing on STM32F303CCT6 revealed that the ADC mux values for B12 and
B13 pins were wrong.
* Add support for all possible analog pins on STM32F1xx
Added ADC mux values for pins A0...A7, B0, B1, C0...C5 on STM32F1xx
(they are the same at least for STM32F103x8 and larger F103 devices, and
also F102, F105, F107 families). Actually tested on STM32F103C8T6
(therefore pins C0...C5 were not tested).
Pins F6...F10, which are present on STM32F103x[C-G] in 144-pin packages,
cannot be supported at the moment, because those pins are connected only
to ADC3, but the ChibiOS ADC driver for STM32F1xx supports only ADC1.
* Add support for all possible analog pins on STM32F4xx
Added ADC mux values for pins A0...A7, B0, B1, C0...C5 and optionally
F3...F10 (if STM32_ADC_USE_ADC3 is enabled). These mux values are
apparently the same for all F4xx devices, except some smaller devices may
not have ADC3.
Actually tested on STM32F401CCU6, STM32F401CEU6, STM32F411CEU6 (using
various WeAct “Blackpill” boards); only pins A0...A7, B0, B1 were tested.
Pins F3...F10 are inside `#if STM32_ADC_USE_ADC3` because some devices
which don't have ADC3 also don't have the GPIOF port, therefore the code
which refers to Fx pins does not compile.
* Fix STM32F3xx ADC mux table in documentation
The ADC driver documentation had some errors in the mux table for STM32F3xx.
Fix this table to match the datasheet and the actual code (mux settings for
B12 and B13 were also tested on a real STM32F303CCT6 chip).

This converts the array that the Swap Hands feature uses to use PROGMEM,
and to read from that array, as such. Since this array never changes at
runtime, there is no reason to keep it in memory. Especially for AVR
boards, as memory is a precious resource.

* Fixup housekeeping from being invoked twice per loop. (#12933)
* matrix: wait for row signal to go HIGH for every row (#12945)
I noticed this discrepancy (last row of the matrix treated differently than the
others) when optimizing the input latency of my keyboard controller, see also
https://michael.stapelberg.ch/posts/2021-05-08-keyboard-input-latency-qmk-kinesis/
Before this commit, when tuning the delays I noticed ghost key presses when
pressing the F2 key, which is on the last row of the keyboard matrix: the
dead_grave key, which is on the first row of the keyboard matrix, would be
incorrectly detected as pressed.
After this commit, all keyboard matrix rows are interpreted correctly.
I suspect that my setup is more susceptible to this nuance than others because I
use GPIO_INPUT_PIN_DELAY=0 and hence don’t have another delay that might mask
the problem.

* Redo Arm DAC implementation for additive, wavetable synthesis, sample playback
changes by Jack Humbert on an implementation for DAC audio on arm/chibios platforms
this commits bundles the changes from the arm-dac-work branch focused on audio/audio_arm.* into one commit (leaving out the test-keyboard)
f52faeb5d (origin/arm-dac-work) add sample and wavetable examples, parsers for both
-> only the changes on audio_arm_.*, the keyboard related parts are split off to a separate commit
bfe468ef1 start morphing wavetable
474d100b5 refined a bit
208bee10f play_notes working
3e6478b0b start in-place documentation of dac settings
3e1826a33 fixed blip (rounding error), other waves, added key selection (left/right)

* Redo Arm DAC implementation for additive, wavetable synthesis, sample playback
changes by Jack Humbert on an implementation for DAC audio on arm/chibios platforms
this commit splits off the plank example keymap from commit
f52faeb5d (origin/arm-dac-work) add sample and wavetable examples, parsers for both
* refactoring: rename audio_ to reflect their supported hardware-platform and audio-generation method: avr vs arm, and pwm vs dac
* refactoring: deducplicate ISR code to update the pwm duty-cycle and period in the avr-pwm-implementation
pulls three copies of the same code into one function
which should improve readability and maintainability :-)
* refactoring: move common code of arm and avr implementation into a separate/new file
* refactoring: audio_avr_pwm, renaming defines to decouple them from actually used timers, registers and ISRs
* refactoring: audio_avr_pwm - replacing function defines with plain register defines
aligns better with other existing qmk code (and the new audio_arm_pwm) doing similar pwm thing
* add audio-arm-pwm
since not all STM32 have a DAC onboard (STM32F2xx and STM32F3xx), pwm-audio is an alternative (STM32F1xx)
this code works on a "BluePill" clone, with an STM32F103C8B
* clang-format changes on quantum/audio/* only
* audio_arm_dac: stopping the notes caused screeching when using the DAC audio paths
* audio_arm_pwm: use pushpull on the pin; so that a piezzo can be hooked up direclty without additional components (opendrain would require an external pullup)
* refactoring: remove unused file from/for atmel-avr chips
* refactoring: remove unused (avr) wavetable file
* audio_arm_dac: adapt dac_end callback to changed chibios DAC api
the previous chibios (17.6.0) passed along a pointer into the buffer plus a sample_count (which are/already where included in the DACDrivre object) - the current chibios (19.1.0) only passes the driver object.
this patch ports more or less exactly what the previous chibios ISR code did: either have the user-callback work the first or second half of the buffer (dacsample_t pointer, with half the DAC_BUFFER_SIZE samples) by adjusting the pointer and sample count
* audio-arm-dac: show a compile-warning on undefined audio-pins

* audio_arm_dac: switch from exemplary wavetable generation to sine only
sine+triangle+squrare is exemplary, and not realy fit for "production" use
'stairs' are usefull for debugging (hardware, with an oscilloscope)
* audio_arm_dac: enable output buffers in the STM32
to drive external loads without any additional ciruitry - external opamps and such
* audio: prevent out-of-bounds array access
* audio_arm_dac: add output-frequency correcting factor
* audio_arm_pwm: get both the alternate-function and pm-callback variants back into working condition
and do some code-cleanup, refine documentation, ...
* audio_arm_pwm: increase pwm frequency for "higher fidelity"
on the previous .frequency=100000 higher frequency musical notes came out wrong
(frequency measured on a Tektronix TDS2014B)
note | freq | arm-pwm
C2 | 65.4 | 65.491
C5 | 523.25 | 523.93
C6 | 1046.5 | 1053.38
C7 | 2093 | 2129
C8 | 4186 | 4350.91
with .frequency = 500000
C8 | 4186 | 4204.6
* audio refactoring: remove unused variables
* audio_arm_dac: calibrate note tempo: with a tempo of 60beats-per-second a whole-note should last for exactly one second
* audio: allow feature selection in rules.mk
so the user can switch the audio driver between DAC and PWM on STM32 boards which support both (STM32F2 and up)
or select the "pin alternate" pwm mode, for example on STM32F103
* audio-refactoring: move codeblocks in audio.[ch] into more coherent groups
and add some inline documentation
* audio-refactoring: cleanup and streamline common code between audio_arm_[dac|pwm]
untangeling the relation between audio.c and the two drivers
and adding more documenting comments :-)
* audio_avr_pwm: getting it back into working condition, and cleanup+refactor
* audio-refactoring: documentation and typo fixes

* audio-refactoring: cleanup defines, inludes and remove debug-prints
* audio_chibios_dac: define&use a minimal sampling rate, based on the available tone-range
to ease up on the cpu-load, while still rendering the higher notes/tones sufficiently
also reenable the lower tones, since with the new implementation there is no evidence of them still beeing 'bugged'
* audio-refactoring: one common AUDIO_MAX_VOICES define for all audio-drivers
* audio-chibios-pwm: pwm-pin-allternate: make the the timer, timer-channel and alternate function user-#definable
* audio_chibios_dac: math.h has fmod for this
* Redo Arm DAC implementation for additive, wavetable synthesis, sample playback
update Jack Humberts dac-example keymaps for the slight changes in the audio-dac interface
* audio-refactoring: use a common AUDIO_PIN configuration switch instead of defines
have the user select a pin by configuration in rules.mk instead of a define in config.h
has the advantage of beeing in a common form/pattern across all audio-driver implementations
* audio-refactoring: switch backlight_avr.c to the new AUDIO_PIN defines
* audio-common: have advance_note return a boolean if the note changed, to the next one in the melody beeing played
* audio-chibios-pwm: fix issue with ~130ms silence between note/frequency changes while playing a SONG
through trial,error and a scope/logic analyzer figured out Chibios-PWMDriver (at least in the current version) misbehaves if the initial period is set to zero (or one; two seems to work); when thats the case subsequent calls to 'pwmChhangePeriod' + pwmEnableChannel took ~135ms of silence, before the PWM continued with the new frequency...
* audio-refactoring: get 'play_note' working again
with a limited number of available voices (say AUDIO_VOICES_MAX=1) allow new frequencies to be played, by discarding the oldest one in the 'frequencies' queue
* audio: set the fallback driver to DAC for chibios and PWM for all others (==avr at the moment)
* audio-refactoring: moore documentation
and some cleanup
* audio-avr-pwm: no fallback on unset AUDIO_PIN
this seems to be the expected behaviour by some keyboards (looking at ckeys/handwire_101:default) which otherwise fail to build because the firmware-image ends up beeing too large for the atmega... so we fail silently instead to keep travis happy
* audio-refactoring: untangling terminology: voice->tone
the code actually was working on tones (combination of pitch/frequency, duration, timbre, intensity/volume) and not voices (characteristic sound of an instrument; think piano vs guitar, which can be played together, each having its own "track" = voice on a music sheet)
* audio-pwm: allow freq=0 aka a pause/rest in a SONG
continue processing, but do not enable pwm units, since freq=0 wouldn't produce any sound anyway (and lead to division by zero on that occasion)
* audio-refactoring: audio_advance_note -> audio_advance_state
since it does not only affect 'one note', but the internally kept state as a whole
* audio-refactoring: untangling terminology: polyphony
the feature om the "inherited" avr code has little to do with polyphony (see wikipedia), but is more a time-multiplexing feature, to work around hardware limitations - like only having one pwm channel, that could on its own only reproduce one voice/instrument at a time
* audio-chibios-dac: add zero-c |
