GPIO Modes

6.2.1

GPIO Mode 0: Input

When a GPIO pin is put into GPIO Mode 0 it is configured to accept external trigger signals. See
Communication.
6.2.2

GPIO Mode 1: Output

When a GPIO pin is put into GPIO Mode 1 it is configured to send output signals.
6.2.3

GPIO Mode 2: Asynchronous (External) Trigger

When a GPIO pin is put into GPIO Mode 2, and an external trigger mode is enabled (which disables isochronous
data transmission), the camera can be asynchronously triggered to grab an image by sending a voltage transition
to the pin. See Asynchronous
6.2.4

GPIO Mode 3: Strobe

A GPIO pin in GPIO Mode 3 outputs a voltage pulse of fixed delay, either relative to the start of integration (default)
or relative to the time of an asynchronous trigger. A GPIO pin in this mode can be configured to output a variable
strobe pattern. See
6.2.5 GPIO Mode 4: Pulse Width Modulation (PWM)
When a GPIO pin is set to GPIO Mode 4, the pin outputs a specified number of pulses with programmable high
and low duration. See

Warning! Do not connect power to a pin configured as an
output (effectively connecting two outputs to each other). Doing
so can cause damage to camera electronics.
