Using the c2000lib Blockset

This section uses an example to demonstrate how to create a Simulink model

that uses the Embedded Target for TI C2000 DSP blocks to target your board.

The example creates a model that performs PWM duty cycle control via pulse

width change. It uses the C2812 ADC block to sample an analog voltage and

the C2812 PWM block to generate a pulse waveform. The analog voltage

controls the duty cycle of the PWM and you can observe the duty cycle change

on the oscilloscope. This model is also provided in the Demos library. Note that

the model in the Demos library also includes a model simulation.

Hardware Setup

The following hardware is needed for this example:

• Spectrum Digital eZdsp F2812

• Function generator

• Oscilloscope and probes

Connect the hardware as follows:

1 Connect the function generator output to the ADC input ADCINA0 on the

eZdsp F2812.

2 Connect the output of PWM1 on the eZdsp F2812 to the analog input of the

oscilloscope.

Starting the c2000lib Library

At the MATLAB prompt, type

c2000lib

to open the c2000lib library blockset, which contains libraries of blocks

designed for targeting your board.
