A demonstration of how to drive the onboard LEDS on the LPC1768 via a 4.3 inch touch-screen display from 4D Systems
Homepage
A quick example program to show how to use the mbed LPC1768 with the 4D systems 4.3 inch capacitive touch screen.
The display has four vitual winButton objects which when touched change the state of four virtual led (userLed) objects. The winButton objects on change of state send a serial message out to the Mbed serial port on pins 9 and 10.
This message tells the mbed to drive actual corresponding virtual and actual LEDS 1 to 4 appropriately.
