6.4.1 Import the LVHBridge component into Processor Expert library

1. Launch CodeWarrior by clicking the CodeWarrior icon (located on your desktop or in

Program Files -> NXP Codewarrior folder.)

2. When the CodeWarrior IDE opens, go to the menu bar and click 

Processor Expert

 ->

Import Component(s)

.

3. In the pop-up window, locate the component file (.PEupd) in the example project

folder LVHBridge_PEx_SW\Component.

4. Select LVHBridge_b1508.PEupd and ChannelAllocator_b1508.PEupd files, and then

click 

Open
