* setup ili9341 framework used epaper-waveshare as start * first version working * added models for now only M5Stack * get_buffer_length is huge * fill, low/high watermark, buffer tests failed. RAM is to small for ili9341 16 bit color mode * removed high/low watermark debug log * added standard 2.4" TFT model * code cleanup * make ledpin optional busy pin is not needed * make bufer 1 byte to avoid the buffer allocation error * gitignore * added backlight pin to dump_config * huge speed increase 8bit color framebuffer (256 colors) lo and high watermark for drawing to screen * fix for images * higher spi data rates * Set spi data rate to 40Mhz Experimental * fixed: formatting fixed: the last row and column being trimmed fixed: namings * Update the code to use Color class * fixed minor color things * fixed linting * #patch minor fixes * fix gitignore too * Update esphome/components/ili9341/ili9341_display.cpp Co-authored-by: Oleg <epushiron+github@gmail.com> * reverting the changes as it's being fixed in PR-1241 Co-authored-by: Michiel van Turnhout <qris.online@gmail.com> Co-authored-by: Michiel van Turnhout <m.vanturnhout@exxellence.nl> Co-authored-by: Oleg <epushiron+github@gmail.com>
