7:Configurable Pin Manager

The Configurable Pin Manager (CPM) is responsible for the assignment and control of the configurable pins (CPs) available on the xPico Wi-Fi embedded device server. There are eight configurable pins on the xPico Wi-Fi unit.

You must configure the CPs by making them part of a role. A CP role may consist of one or more CPs. This increases flexibility when incorporating the xPico Wi-Fi device into another system.

Note: The blue text in the XML command strings of this chapter are to be replaced with a user-specified name.

Configurable Pin Status

Each CP is associated with an external hardware pin. The Current Configuration table shows the sample settings for each CP.
