pathae 0:98f39b4055ea 1 /* A port test of the arduino voltmeter example using the
pathae 0:98f39b4055ea 2 4.3' PCT 4d systems touch screen display.
pathae 0:98f39b4055ea 3
pathae 0:98f39b4055ea 4 uses the mbed_genie library ported from the arduino
pathae 0:98f39b4055ea 5 visie-genie library by Christian B
pathae 0:98f39b4055ea 6
pathae 0:98f39b4055ea 7 The display serial TX and RX pins are connected to pin 9
pathae 0:98f39b4055ea 8 and pin 10 of the mbed
pathae 0:98f39b4055ea 9
pathae 0:98f39b4055ea 10 The reset pin is not connected as reset function is not implemented
pathae 0:98f39b4055ea 11
pathae 0:98f39b4055ea 12 Pin 15 of the mbed has a potentiometer wiper connected to it
pathae 0:98f39b4055ea 13 The other connections of the potentiometer are connected to +3.3V
pathae 0:98f39b4055ea 14 and 0V
pathae 0:98f39b4055ea 15
pathae 0:98f39b4055ea 16 For setting up the display in Visie-Genie
pathae 0:98f39b4055ea 17
pathae 0:98f39b4055ea 18 The display has an angular meter objecr, a LED digits object, two buttons
pathae 0:98f39b4055ea 19 and three static text objects.
pathae 0:98f39b4055ea 20
pathae 0:98f39b4055ea 21 The program sends digital voltage readings to the LED digits and
pathae 0:98f39b4055ea 22 angular meter of the display module.
pathae 0:98f39b4055ea 23
pathae 0:98f39b4055ea 24 The On and Off button has been set to report on change
pathae 0:98f39b4055ea 25
pathae 0:98f39b4055ea 26 The baud rate of the display is set to 115200 baud
