Overview#

The EEPROM Example project is a demonstration program that uses the KSDK software to program eeprom memory and verify the program.

Prepare the Demo#

Connect a serial cable from the debug UART port of the board to the PC. Start Tera Term (http://ttssh2.osdn.jp) and make a connection to the virtual serial port.

  1. Start Tera Term

  2. New connection -> Serial

  3. Set apropriate COMx port (x is port number) in Port context menu. Number is provided by operation system and could be different from computer to computer. Select COM number related to virtual serial port. Confirm selected port by OK button.

  4. Set following connection parameters in menu Setup->Serial port… Baud rate: 115200 Data: 8 Parity: none Stop: 1 Flow control: one

  5. Confirm selected parameters by OK button.

Running the demo#

Example output on terminal:

EEPROM example begins… Page 0 program finished! Page 1 program finished! Page 2 program finished! Page 3 program finished! Page 4 program finished! Page 5 program finished! Page 6 program finished! Page 7 program finished! Page 8 program finished! Page 9 program finished! … Page 126 program finished! All data is correct! EEPROM example succeed!

Supported Boards#

LPCXpresso54628
Hardware requirements

  • Micro USB cable

  • LPCXpresso54628 board

  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a micro USB cable between the host PC and the LPC-Link USB port (J8) on the target board.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
