Microchip Technology Inc. announced Version 3.30 of its MPLAB® Device Blocks for Simulink®, which make it easy to develop complex designs using Microchip’s dsPIC30 and dsPIC33 digital signal controllers (DSCs). This software provides a set of user interfaces to MathWorks’ Simulink graphical environment for simulation and model-based design, where code for the application is generated, compiled and loaded onto a target dsPIC DSC in a single, one-click step. Updates to this version include multi-rate and interrupt-capable device blocks, as well as a Free edition for up to seven I/O ports that eliminates the compile wait time found on prior Free editions. Existing users can upgrade to the new PRO edition for free. The Device Blocks are also simple to set up and one configuration can be used across all dsPIC DSCs, which enables easy in-process design changes and seamless migration. Target configuration blocks include Master Block, Simulink Reset Config, Compiler Option and Data Sheet. The Device Blocks’ facility to invoke dsPIC3X dedicated functions written in C, via a C function-call block, allows designers to write less code by utilizing many of Microchip’s numerous application, algorithm and operation libraries directly from a Simulink model.
