JackB 0:cc1fb45bc3ad 10 by Jack Berkhout 23-11-2016
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)
