adding Hadron v3 keyboard, QWIIC devices support, haptic feedback support (#4462) * add initial support for hadron ver3 * add initial support for hadron ver3 * pull qwiic support for micro_led to be modified for use in hadron's 64x24 ssd1306 oled display * initial work on OLED using qwiic driver * early work to get 128x32 oled working by redefining qwiic micro oled parameters. Currently working, but would affect qwiic's micro oled functionality * moved oled defines to config.h and added ifndef to micro_oled driver * WORKING :D - note, still work in progress to get the start location correct on the 128x32 display. * added equation to automatically calculate display offset based on screen width * adding time-out timer to oled display * changed read lock staus via read_led_state * lock indications fixes * Added scroll lock indication to oled * add support for DRV2605 haptic driver * Improve readabiity of DRV2605 driver. -added typedef for waveform library -added unions for registers * Update keyboards/hadron/ver2/keymaps/default/config.h Co-Authored-By: ishtob <ishtob@gmail.com> * Update keyboards/hadron/ver2/keymaps/default/config.h Co-Authored-By: ishtob <ishtob@gmail.com> * Update keyboards/hadron/ver2/keymaps/default/config.h Co-Authored-By: ishtob <ishtob@gmail.com> * Update keyboards/hadron/ver2/keymaps/default/config.h Co-Authored-By: ishtob <ishtob@gmail.com> * Fixes for PR * PR fixes * fix old persistent layer function to use new set_single_persistent_default_layer * fix issues with changing makefile defines that broken per-key haptic pulse * Comment fixes * Add definable parameter and auto-calibration based on motor choice
