MCAL DIO Channel Write

Write logical value to a specified DIO channel identifier

Since R2026a

Libraries:
Embedded Coder Support Package for Renesas RH850 Microcontrollers / Microcontroller Abstraction Layer (MCAL) Blocks

Description

Use the MCAL DIO Channel Write block to write the logical value of a specified channel identifier. The block accepts a logical value as input and writes this value to the selected DIO channel at each simulation step or sample time.

Before using this block, configure pin modes and DIO channels, select the Configuration Description File (CDF) in Simulink model configuration, and then integrate the block into your target-specific model for code generation and deployment. For information on configuring correct and portable Digital Input/Output (DIO) workflow using the MCAL DIO module in Simulink and AUTOSAR-based projects, see Getting Started With DIO Using MCAL.

Examples

Getting Started with MCAL DIO Blocks on Renesas RH850 Microcontrollers

Control a digital output on a Renesas RH850/U2A16 Microcontroller using the AUTOSAR MCAL DIO Channel Write block in Simulink. The example uses an onboard LED to demonstrate how MCAL DIO configuration and model-based design work together to generate, deploy, and run the model on RH850 hardware to drive an LED.

Channel — Channel value
scalar

Writes the logical value provided to the selected DIO channel.

Parameters

Channel identifier — Specific input/output channels to read
`'DioChannel'` (default)

Specify the unique identifier for the DIO channel to be written. This links the MCAL DIO Channel Write block to a specific digital output channels as configured in the CDF file. Click Get dio channels to view and select from the list of available channel group names configured in the CDF.
