Digital Port Pins Read

R2026b

Read logical states from group of pins/channels on a specified port

Since R2026a

Digital Port Pins Read block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Embedded Coder Support Package for Renesas RA Microcontrollers / Renesas RA6 Based

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

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

P000 — Logical states for the channel

scalar

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

Pin(s) — Logical state(s) of the specified port pins

scalar | vector

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

Port — Port for pin read

0 (default)

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

Programmatic Use

Block Parameter: PortName

Select group of pins/channels — Enable to specify a group of pins or channels

on (default) | off

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

Programmatic Use

Block Parameter: IndividualPinsRead

Pin(s) — pins/channels to read

0 (default)

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

Separate output for each channel — Output multiple pin values

on (default) | off

Select this parameter to output multiple port pin values.

Programmatic Use

Block Parameter: EachPinAsOutput

Sample time — Frequency at which block reads input pin value

-1 (default) | scalar | vector

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

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

Example: add_block("ra6basedlib/Digital Port Pins Read","myModel/myBlock",MakeNameUnique="on")
