Hi,

I am looking for advice and insight on how to use the writePWMDutycycle and writePWMVoltage function in MATLAB arduino interface. I have installed the arduino PDE sketch to my arduino and installed the arduino hardware support package in MATLAB. However, I the writePWMDutycycle or writePWMVoltage functions show up a as undefined functions whenever I attempt to use them.

Do I need to upload an different version of the arduino PDE sketch to allow the use of these functions?

Thanks,

Hi chucktehengineer,

Is it only the 'writePWMDutycycle' and 'writePWMVoltage' functions from Arduino MATLAB support Package that are erring out ? Are the functions 'arduino', 'configureDigitalPin', 'readDigitalPin', 'writeDigitalPin' etc working ?

If the other functions are also not working, it looks like you may have not installed the MATLAB Arduino Support Package properly.

Thanks, Abhishek

Hi Abhishek,

Thanks for replying. I can use the 'arduino', 'configureDigitalPin,'readDigitalPin', 'writeDitialPin', and other basic I/O functions. However, the 'writePWMDutycycle', 'writePWMVoltage', and other I/O functions such as 'playtone()'and 'configureAnanlogPin' are not recognized.

I have tried re-installing the Arduino hardware support package several times without any luck.

Thanks,

Chucktehengineer
