Chapter 6 Testing GPIO Functionality 29
Introduction
This chapter describes how to use the development board
switches and the web interface to learn about GPIO
functionality on the Digi Connect ME or Digi Connect EM.
Getting Familiar with GPIO Input
Introduction
This section familiarizes you with GPIO input to the module.
Typically, you will use input signals on GPIO pins to trigger an
email alarm, which tells an administrator or technician that a
significant event has occurred within the device.
Procedure
1. On the SW2 bank of switches on the development board,
ensure that one of the GPIO pins is set to high.
2. On the SW1 bank of switches, set the same GPIO pin to
IO.
3. Configure the GPIO pin for input. See "Configuring the
GPIO Pins" on page 26 for more information.
4. Configure an email alarm. See "Configuring Alarms" on
page 27.
5. Toggle the SW2 switch several times to generate several
email alarms.
