JackB 11:70409b34b74d 5 Changed a lot of things by Jack Berkhout 23-11-2016
JackB 11:70409b34b74d 6
JackB 11:70409b34b74d 7 Used for 2.2" Serial SPI TFT Color LCD Module for Arduino
JackB 11:70409b34b74d 8 176*220 resolution / 11-pin / ILI9225 IC driver
JackB 11:70409b34b74d 9 https://www.fasttech.com/product/3842400-2-2-serial-spi-tft-color-lcd-module-for-arduino
JackB 11:70409b34b74d 10
JackB 1:8e447a4c8995 11 - uses the same fonts as the SPI_TFT_ILI9341 Library (I have many, and a html/php font editor for that)
JackB 0:cc1fb45bc3ad 12 - some code removed, some added, some changed
JackB 0:cc1fb45bc3ad 13 - the led backlight is using a PWM output, so it can be adjusted (0.0f = off - 1.0f = on)
JackB 0:cc1fb45bc3ad 14 - added formatted printf
JackB 0:cc1fb45bc3ad 15 - added claim as standard output on stream
JackB 2:e213811335ac 16 - Orientation definitions are now related to the SD card slot location (front view)
JackB 11:70409b34b74d 17 - hline and vline added, also used by outline reactangles, with drastical performance improvement (15 times)
