Description

This block configures the general-purpose I/O (GPIO) MUX registers that control the operation of GPIO shared pins for digital input. Each I/O port has one MUX register that selects peripheral operation or digital I/O operation (the default). When a pin is configured for digital input, it becomes unavailable for digital output or peripheral operation. You can configure the Input qualification type for individual digital input pins. To configure, go to Configuration Parameters > Hardware Implementation > Target Hardware Resources and select the appropriate GPIO group.

Each processor has a different number of available GPIO pins.

Note

To avoid losing new settings, click Apply before changing the GPIO Group parameter.

Parameters

GPIO Group

Select the group of GPIO pins you want to view or configure. For a table of GPIO pins and peripherals, refer to the Texas Instruments documentation for your specific target.

Sample time

Specify the time interval between output samples. To inherit sample time from the upstream block, set this parameter to -1. For more information, refer to the section on Specify Sample Time (Simulink) in the Simulink® documentation.

Data type

Specify the data type of the input. The input is read as 16-bit integer, and then cast to the selected data type. Valid data types are auto, double, single, int8, uint8, int16, uint16, int32, uint32 or boolean.
