There are different versions of Adafruit 2.8” TFT LCD shields. The shields marked v2.0 works directly with this project. For the other shields, please solder the center pin of IOREF pads to the 3.3V pad, and solder the pads 11, 12, and 13.

Attach the LCD shield to the LPC board.
Short JP25 1-2, JP26 1-2, JP9, Remove JP12 This project does not use the serial port J1, J3-1 for UART RX, J3-2 for UART TX.
Prepare the Demo
Power the board using a micro USB cable connected to J2 USB port on the board, attach debugger to J1 connector
Build the project.
Download the program to the target board.
Reset the SoC and run the project.
Running the demo
Known issue: The MCU is not able to generate hardware reset of the LCD due to hardware limitation of the boards interconnection. Because of this the LCD may not get initialized (stays blank) following a cold start (power on) of the board even if the demo was correctly programmed to the FLASH memory. In such a case simply press the reset button to restart the demo.
