pathae 0:f38ea4ed5621 1 /* 4d systems touch screen display.
pathae 0:f38ea4ed5621 2
pathae 0:f38ea4ed5621 3 uses the mbed_genie library ported from the arduino
pathae 0:f38ea4ed5621 4 visie-genie library by Christian B
pathae 0:f38ea4ed5621 5
pathae 0:f38ea4ed5621 6 The display serial TX and RX pins are connected to pin PA_9
pathae 0:f38ea4ed5621 7 and pin PA_10 of the mbed
pathae 0:f38ea4ed5621 8
pathae 0:f38ea4ed5621 9 The reset pin is not connected as reset function is not implemented
pathae 0:f38ea4ed5621 10
pathae 0:f38ea4ed5621 11 For setting up the display in Visie-Genie
pathae 0:f38ea4ed5621 12
pathae 0:f38ea4ed5621 13 The display has an gauge meter object, a LED digits object, two buttons
pathae 0:f38ea4ed5621 14 and three static text objects.
pathae 0:f38ea4ed5621 15
pathae 0:f38ea4ed5621 16 The On and Off button has been set to report on change
pathae 0:f38ea4ed5621 17 The baud rate of the display is set to 115200 baud
