The goal of this project is to design a 20-Sim Code Generation template for the Analog Devices ADSP-21990 EZ-KIT lite evaluation board using VisualDSP++ 3.0. Also, the gap between simulation and realization should be spanned automatically, so that no manual effort needs to be made to cross this gap. This board, together with the 20-Sim code generation template, can then be used during the mechatronica project for second-year Electrical Engineering students of the University of Twente.
A code generation template has been created, which functions well, making use of the AD- and DAconverters on the evaluation board. Drivers have been designed for these features. The generated software is automatically loaded onto the ADSP-21990 target and executed. Furthermore, 20-Sim library submodels have been designed for the ADC and the DAC, which can be used when constructing 20-Sim models, that have to run on the ADSP-21990 target.
Further work is to make the sample time programmable from the 20-Sim code generator. Also, other peripherals, like encoders, PWM¿s and other I/O should be supported.
