This screen gives the current state of the digital I/O pin. If the pin is configured as an input, the
value will be a 1or a 0 meaning “On” or “Off” respectively. If the pin value is a 1, the input
voltage will be approximately 3.5 volts or higher, (normally 5.0 volts). If the pin value is a 0, the
input voltage will be approximately 0.8 volts or less, (normally 0.0 volts). The range between 0.8
and 3.5 is not defined and may be either a 1 or a 0.
If the pin is configured as an output, the value will be a 1 or a 0 based on whether the output is
set to a 1 or a 0, “On” or “Off” respectively. However, the output may be set to a 1 or a 0, but the
connected equipment may prevent the output from going to the desired state if it is causing too
great a load on the output. In this case the reported value matches the desired state and
not
the
actual state. Other functions for this screen are available based on the mode of the I/O pin as
listed below.
NOTE
: The following statements relate only to the built in keypad / display.
When Configured As An Input
Pressing the ENTER key will display “Digital Input Mode”, indicating the current pin
configuration is an input.
