Powering The Board; Verifying All The Peripherals On Lpc435X-Xplorer - NGX Technologies LPC435x-Xplorer++ Quick Start Manual

Quick Start Guide: LPC435x-Xplorer++

3.2 Powering the Board

The LPC435x-Xplorer++ can be powered through USB1, 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
LPC435x-Xplorer++ 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 LPC435x-Xplorer++

The following section focuses on the verification of all the peripherals supported on theLPC435x-
Xplorer++. 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.
Important Note: The user needs to press the RESET switch to be able to reset the controller. However
for the power up reset (USB power cycle) the controller boots up fine.
Power up the board over USB1 port and we are all set to verify the LPC435x-Xplorer++ peripherals.
Before we get to the verification we need to install the Virtual COM port drivers needed for the
LPC435x-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. Download INF file Click Here
