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.
