CONNECTING THE DEVELOPMENT BOARD
The eCee LPC 2148 requires a 9V-12V adapter or USB connection
for power and either a serial connection for In-system programming,
or the JTAG connector.
Use LPC2000 Flash Utility Software at the PC side for
programming through Serial port. Connect eCee LPC 2148
Development board to your PC using USB cable (for powering it)
and serial cable (for In-serial programming) as shown in the figure.
Note: Serial cable should be connected to COM0 Port of the
development board for downloading. Corresponding jumpers has to
be inserted (see circuit diagram) for the functioning of each
peripheral.
