Description

Configure individual general-purpose input/output (GPIO) pins to operate as digital outputs. When a pin is configured for digital output, it cannot operate as a digital input or connect to peripheral I/O signals. When you select a pin for digital output, the user interface presents a Toggle option that inverts the output signal on the pin.

Each processor has a different number of available GPIO pins.

`Input` — Set the GPIO pin status

The input port to set the GPIO pin status.

Parameters

GPIO Group

Select the group of GPIO pins you want to view or configure.

GPIO pins for output

To configure a GPIO pin for digital output, select the checkbox next to it. Refer to the block for a table of all available peripherals for each pin.

A value of True at the input of the block drives the selected GPIO pin high. A value of False at the input of the block grounds the selected GPIO pin.

Toggle GPIO[bit#]

For each pin selected for output, you can elect to toggle the signal of that pin. In Toggle mode, a value of True at the input of the block switches the GPIO pin output level. Thus, if the GPIO pin was driven high, in Toggle mode, with the value of True at the input, the pin output level is driven low. If the GPIO pin was driven low, in Toggle mode, with the value of True at the input of the block, the same pin output level is driven high. If the input of the block is False, the GPIO pin output level is unaffected.
