Hello,
I'm working with the F28335 microcontroller and with Matlab Simulink (IDE CCSv5). I want to use this µC for an acoustic test station and therefore I need a sine wave or some more difficult continuous signals at the output of the microcontroller. For this purpose I want to use the ePWM block (F28x3x) in Simulink. I tried to work with the following two different examples, but after a few weeks of work I still not sure which one is more suitable for my application:
http://www.mathworks.de/de/help/rtw/examples/adc-pwm-synchronization-via-adc-interrupt.html
The second one you can find in Matlab Help. It’s called
“ADC-PWM Synchronization via ADC Interrupt”
I’m able to run some easy models like blinking the LED on my microcontroller. But I did not succeed in implementing a sine wave or a more complex model in one of these examples. I apparently don’t understand how the pulse width modulation blocks in Simulink work.
I also would like to use the ADC pins to have a microphone signal as an input signal for my Simulink model. Is it possible to drag and drop an ADC block in an existing model to use it as a source, or is it a bit more difficult?
With kind regards
Max
