MCAL DIO Channel Group Write

Write value to the specified DIO channel group identifier

Since R2026a

• 

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

Description

Use the MCAL DIO Channel Group Write block to write a chosen value to a set of adjoining bits in a port, determined by the channel group identifier. The channel group must be configured in the CDF (Configuration Description File).

The block accepts a integer value as input and writes this value to the selected DIO channel group at each simulation step or sample time.

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.
