- There was a bug in power up sequence that was causing Inkplate to stuck in refresh, due to do/while loop.
Bad power up also caused partial updat to not work properly.
- Now temperature measurment is not dependent to screen refresh. Now you can read temperature from Inkplate built-in sensor anytime you want! Because of that, macros for powering up/down TPS65186 are moved from Inkplate.cpp to defines.h
- Removed unused functions and variables for gamma correction
- Improved cleaning (little bit slower, but better)
- Fixed epaper power up / power down bug that caused problems on some epaper panels (random vertical black lines). Some informations on how to properly pwr up/down TPS65186 Epaper PMIC is missing in datasheet.
- Better cleaning (for some reason, whilte color can easly "overcharge" screen, so now the are less white frames than black ones). [This problem is visible if the panel is refreshed multiple times in a row, screen after has been powerd down starts to fade]
- Improved HW sequence (there was some issue with line clock and start pulse vertical signal)
- Removed vscan_write() function (it's not needed anymore).
- Some minor bug fixes
