User Manual: LPC4330-Xplorer

3.2 Powering the Board
The LPC4330-Xplorer can be powered through USB; we can either power it from USB0 port or USB1
port. It is highly recommended that the user tests all the peripherals as soon as the board is received. A
regulated supply can be supplied to the 5V pin on the Xplorer-LPC4330 header.
Note: The USB power can source only up to 500 mA of current. For applications having higher current
requirements we recommend to use an external power supply. Please note that the external power supply
is not a part of standard delivery.
3.3 Verifying all the peripherals on LPC4330-Xplorer
The following section focuses on the verification of all the peripherals supported on the LPC4330Xplorer.
The order of the tests is mentioned in the same manner as the flow of the test firmware. We highly
recommend that you follow the order of the test. The test firmware is designed in a manner that the user
needs to spend as minimum time as possible to verify all the on-board peripherals. The test firmware
executable resides on the Quad Flash. The BOOT select switch is configured to execute from the Quad
Flash interface.
Note: The test firmware “Debug Messages” or flow might be changed in due course. Generally these are
only cosmetic changes so that the usage is easier. If you observe a different message than the one
mentioned in the Manual, do not worry and please proceed with the test
Note: To restore the Factory Default for LPC4330 Xplorer Board
kindly refer to section 6.0
Important Note: The user needs to press the RESET switch twice to be able to reset the controller. This
is due to the issue with the silicon. Please note that if you power-up the board then it would have been
reset once (power-on reset) and in this case you need to press the RESET switch only once for the
controller to reset. In situations where the Xplorer is powered up and running a firmware and you wish
to reset the controller, one needs to press the RESET switch twice.
Power up the board over USB1 port and we are all set to verify the LPC4330-Xplorer peripherals.
Before we get to the verification we need to install the Virtual COM port drivers needed for the LPC4330-
Xplorer (USB1 port) to appear as a Virtual COM port (Used for viewing the debug messages on serial
emulation tool). Fortunately, this is a one-time setup and fairly simple. On a Windows machine the user
needs to point to the location of the INF file (the INF file can be found in the download folder provided
on
product
registration;
the
path
for
INF
file
is:
..\Xplorer_release\LPC4330_Xplorer_Examples_V1\LPC4330_Xplrer_UsbVcomLib
).
