-/* 4d systems touch screen display.
-
-uses the mbed_genie library ported from the arduino
-visie-genie library by Christian B
-
-The display serial TX and RX pins are connected to pin PA_9
-and pin PA_10 of the mbed
-
-The reset pin is not connected as reset function is not implemented
-
-For setting up the display in Visie-Genie
-
-The display has an gauge meter object, a LED digits object, two buttons
-and three static text objects.
-
-The On and Off button has been set to report on change
-The baud rate of the display is set to 115200 baud
