* Add stm32f072 base ck4x4 to handwired * add prints * Save these tries * Save changes again * Working hadron oled * OLEd working but ws2812b still iffy: * save another try * Encoder feature + OLED * RTC code * Implement clock setting mode * Whitespace * Encoder hooked up to working LED PWM code * Add missing files * eeprom changes * Save changes * Move i2c master * Move satisfaction75 under cannonkeys * Set proper default folder * Revert some core changes * Undo paved iris changes * Reorganize code for maintainability and prep for new features * Add starting code for clock OLED mode * Clock set mode finished * Add custom encoder modes * Actually add VIA keymap * Gate to only 072 * fix gate for only 072 * Update header guards and includes * Update i2c selection strategy * Update board.c to handle software reset to DFU

* This library assumes 8-bit data locations. To add a new MCU, please provide the flash
|
|
* page size and the total flash size in Kb. The number of available pages must be a multiple
|
|
* of 2. Only half of the pages account for the total EEPROM size.
|
|
* This library also assumes that the pages are not used by the firmware.
