Description

Use the Digital Port Pins Read block to read the logical value from a specified group of channels within a port.

Examples

Getting Started with Renesas RA Microcontroller Boards

Getting Started with Renesas RA Microcontroller Boards

Use the Embedded Coder ® Support Package for Renesas® RA Microcontrollers to deploy and simulate a Simulink® model on hardware based on Renesas RA microcontrollers. With this support package, you can access hardware peripherals at run time using Simulink® blocks and configure those peripherals through the Renesas RA Smart Configurator tool.

Ports

Output

expand all

Logical state for the pin/channel you specify within the selected port. The numeric suffix (0 -15) for the channel reflects the value specified in the Pins parameter

Dependencies

To enable this port, Select group of pins/channels and Separate input for each pin parameters must be selected.

Data Types: int8 | uint8 | uint32 | Boolean

Logical state (high or low) of the selected pins/channels on the specified port.

When the block outputs a vector, the element order follows the order of pin indices specified in the Pin(s) parameter. For example, if the selected port is PA and Pin(s) is set to [10 5 8], the output vector maps as follows:

  • output(1) → PA10

  • output(2) → PA5

  • output(3) → PA8

The output value follow the order of pins specified in the Pin(s) parameter:

  • The first pin specified corresponds to the least significant bit (LSB).

  • The last pin specified corresponds to the most significant bit (MSB).

Dependencies

This output port is available when either of the following conditions is met:

  • Select group of pins/channels is cleared, or

  • Select group of pins/channels is selected and Separate output for each pin is cleared.

Data Types: uint16

Parameters

expand all

Specify the unique identifier for the port. This links the block to a specific hardware instance or configuration.

Programmatic Use

Block Parameter: PortName

Select this parameter to specify a group of pins or channels to read.

Programmatic Use

Block Parameter: IndividualPinsRead

Specify the pin or channel index (0–15) to read. The specified value is appended as a numeric suffix to the Channel000 output port. For example, specifying 1, results in the output port name Channel001.

Programmatic Use

Block Parameter: PinNumbers

Select this parameter to output multiple port pin values.

Programmatic Use

Block Parameter: EachPinAsOutput

Specify in seconds how often this block reads the pin value.

When you specify this parameter as -1, Simulink® determines the best sample time for the block based on the block context within the model.

Programmatic Use

Block Parameter: SampleTime
