How to change pulse width modulation FREQUENCY of arduino analog pins with new support package for R2014b?
3 views (last 30 days)
I need to change the pulse-width modulation FREQUENCY (not the duty cycle) of the arduino analog pins for my applications. With the previous arduinoio package for matlab ( http://www.mathworks.com/matlabcentral/fileexchange/32374-matlab-support-for-arduino--aka-arduinoio-package-), one had to upload the sketch to the arduino manually, but the advantage was that this enabled the user to add some lines to the setup() function in the sketch that would change the PWM frequency of the pins.
The R2014b matlab support package for arduino (<http://www.mathworks.com/matlabcentral/fileexchange/47522-matlab-support-package-for-arduino%C2%AE-hardware>) replaces the existing sketch on the arduino by an auto-generated one upon executing the command arduino(port) and I have no control over what's actually being uploaded to the arduino.
Can anyone tell me, how to change the PWM frequencies with new package?
Thanks so much! Wolfgang

You can add a S-function builder block on the sketch to include custom code to be run either in setup() or loop().
Lots of details here http://jp.mathworks.com/matlabcentral/fileexchange/39354-device-drivers
I think you should then be able to use the code you used in the previous package.
Best Regards, Martin

Dear Wolfgang can you tell me how to change the pwm frequency in the previous support package you are talking about, as i need it very urgent for my project and i tried a lot to change it with the previous package but couldnt succeed. can you send me one example. Thanks alot
