2021-10-26feat(kscan): Improve matrix debouncingJoel Spadin
Switched the GPIO matrix driver to debouncing using a simple integrator algorithm. Whenever a key is pressed, we now scan at a rate controlled by debounce-scan-period-ms (default 1 ms) until all keys are released, then return to either waiting for an interrupt or polling more slowly. The timers for key press and release can now be controlled separately, so debounce-period is deprecated in favor of debounce-press-ms and debounce-release-ms. Global Kconfig options ZMK_KSCAN_DEBOUNCE_PRESS_MS and ZMK_KSCAN_DEBOUNCE_RELEASE_MS are also added to make these easier to set. Added documentation for debouncing options.
2021-09-14fix(kscan): Allow composite driver to handle missing children.Pete Johanson
For split keyboards using an IO expander over TRRS/i2c, if the right half isn't connected, we should be able to gracefully fallback to the left side still working.
2021-09-14feat(drivers): Add mcp23017 driver based on upstream mcp23s17 one.Pete Johanson
* Upstream Zephyr has in progress driver, so doing this locally here, until we can move over to that driver.
2021-09-08refactor(kscan): Demacroify GPIO matrix driverJoel Spadin
Refactored the GPIO matrix kscan driver so that only the data and config structures are defined in the foreach macro. Functionality is unchanged except for the addition of DT properties to adjust polling speed. This should make it easier to add other enhancements later, like improved and customizable debounce behavior.
2021-08-24feat(display): IL0323 driver for EPD displays.Darryldh
* Basic driver, using the GD7965 driver as a basis, since the ICs are very similar.
2021-07-24feat: Add nrf VDDH battery driverJoel Spadin
Added a driver which uses the nRF52's ADC channel on the VDDH pin to read the battery voltage when using high voltage mode.
2021-07-17refactor(core): Move away from deprecated DT API.Pete Johanson
* Move to `DEVICE_DT_INST_DEFINE` everywhere. See: https://docs.zephyrproject.org/2.5.0/releases/release-notes-2.5.html#deprecated-in-this-release PR: https://github.com/zmkfirmware/zmk/pull/736
2021-06-08fix(kscan): Fix nibble demux scan errors on encoder rowJay Greco
+ Add a 1us sleep to let the column selection settle in order to avoid spurious keypresses when row capacitance is high (like on the encoder row)

2021-02-04fix(power): Add support for capacitors on ADC for BVDjrhrsmit
Add a little delay so any capacitors connected to the ADC for the BVD can charge up when using power_gpios Co-authored-by: Jasper Smit <jrhrsmit@gmail.com>
2021-02-02refactor(kscan): Fix polling of GPIO matrices.Pete Johanson
* Add easier macros for conditional polling/interrupt code. * Properly continue polling on intervals, without extra enable/disable code for pins that is superfluous when not trying to deal with interupts firing. * Fix to allow multiple GPIO drivers when doing splits w/ IO expanders
2021-02-02refactor(kscan): Remove explicit default n from kscan configs.Pete Johanson
* Actually allow defaulting yes in other places.

2020-12-02refactor(kscan): Use PORT events for direct driverPete Johanson
* Switch interrupt configuration so nRF52 uses PORT events for lower power use, and wake from deep sleep. * Closes #272
2020-11-29Updated function calls with missing reference. GPIO missing.4pplet
Updated function calls with missing reference. GPIO missing. To my understanding: DT_INST_GPIO_PIN() should be called instead if DT_INST_PIN() DT_INST_GPIO_FLAGS() should be called instead if DT_INST_GPIO_FLAGS() Current implementation does not compile when using control pin.

Use PORT events for kscan matrix interrupts, add option for deep sleep.
2020-10-06feat(power): Initial deep sleep work.Pete Johanson
* New ZMK_SLEEP Kconfig symbol to enable the functionality. * Switch to PORT events that allows wake from deep sleep. * Initial basic power management policy, with idle ms, and ignoring deep sleep if we detect a USB connection.

2020-10-04fix(kscan): fix direct GPIO when using interruptsJoel Spadin
Fixed initializing interrupts for direct GPIO when CONFIG_ZMK_KSCAN_DIRECT_POLLING is not enabled. IS_ENABLED() is needed to map the possibly-undefined value to 0 or 1 so COND_CODE_0() and COND_CODE_1() work.
