GPI - General purpose inputs

At the hardware level, GPI inputs are general-purpose digital inputs that can be configured for various purposes. This block and the associated C/C++ routines provide means to read the value of the corresponding pin at the CPU execution rate. For FPGA users, GPI pins are also available in the sandbox, enabling faster sampling rates.

The table below outlines the location and logic-voltage levels of the FLT inputs across imperix controllers. Detailed information is available in the product datasheets. For the TPI8032, using the TPI GPI helper block is recommended instead.

Simulink block

Signal specification

The output signal returns the value of one GPI pin.

Parameters

• Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
• GPI pin(s) (vectorizable) a selection of GPI pin(s) to read. It can be a single value or a vector.
• Show simulation input port defines whether the simulation input is displayed.

PLECS block

Signal specification

The output signal returns the value of one GPI pin.

Parameters

• Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
• GPI pin(s) (vectorizable) a selection of GPI pin(s) to read. It can be a single value or a vector.
• Simulation input port defines if the target inport is displayed or not. This parameter is only used in simulation.
