Indigenous Design and Development of Interface Board for TMS320F28335 DSP and Programming via MATLAB Simulink Embedded Coder

This paper presents an indigenous design and development of an interface board, interfacing different micro-controller peripherals and sensors, for the Texas Instruments TMS320F28335 Digital Signal Processor (DSP), with a focus on its integration with MATLAB Simulink Embedded Coder to do efficient programming and code deployment. The developed interface board, having essential hardware, provides a reliable and seamless connection between the TMS320F28335 DSP and the development environment, enabling real-time control, signal and data processing tasks for various embedded control systems. MATLAB Simulink Embedded Coder is employed to generate C code for the TMS320F28335 through automatic code generation and direct deployment of algorithms to the DSP streamlining the development process for embedded applications. This paper discusses the hardware components of the interface board along with communication protocols and configuration of various C2000 microcontroller blocks for software integration with MATLAB, highlighting its versatility and ease of use for real-time embedded system development. A case study of real-time implementation of closed-loop v/f control of induction motor is presented and the obtained results demonstrate the efficacy of the interface board while enabling its efficient programming and operation. This work contributes a viable, customizable solution for the students, researchers, and engineers started working with TMS320F28335 DSPs and Embedded Coder, promoting enhanced productivity and flexibility in embedded system development.
