Overview

The task of the work was to check the generation of C-code for an ARM Cortex-M3 processor of the LPC4078FBD208 (NXP) type using MatLab tools.

The goal was to reduce the development time of object-oriented code.

To generate the optimal C-code was used Matlab support package - Supported CMSIS Functions for ARM Cortex-M Processors.

 

The process of generating C code from a Simulink model and programming the processor includes the following steps:

• developing a model in Simulink;

• setting model parameters and variables in Simulink;

• generation of C-code;

• connecting the generated code to the template project;

• programming the control board;

• checking the program operation in debug mode.

 

The tests were carried out in several stages:

• debugging on the open-loop mode

• debugging on the close-loop mode

• laboratory tests on power electrical equipment based on DC motor 5kW, 440V.

 

The control board worked in standalone mode.

In the program, the subsystems were divided into interrupt-running and background-running subsystems, as well as running with different sample times.

Achievements

• reduce development time for object-oriented code

• ability to change the control algorithm (simulation - automatic C-code generation -  laboratory tests)
