3.5 Alternative functions – digital input
Using the pin as an input is useful for simple feedback, without the
use of telemetry sensors.
For example: if you attach limit switches to retractable gear, you can
have feedback about its condition during the flight. The condition
of the digital inputs is sent via EX telemetry and the user can assign
sounds or alarms to the events.
Here the pin is configured as an input and its condition
(disconnected / connected to the ground) is sent to the transmitter
as other telemetry data from the sensors.
- Only keep the pin disconnected or connected to the common
ground of the Central Box.
- Never connect to a different voltage. The pin works exclusively in
PullUp mode.
