I think a function to set the PWM frequency will appear in an upcoming version of Arduino.

Any news on this?

thanks, e.

In newer versions of Matlab, there is a Timer object that can call a given function at regular intervals. There is also a timer specifically associated with the Serial port object that dates back to Matlab 6.0 at least.

cheers, e.

Anyone has an idea how a serial mouse on RS232 worked ?

The serial protocol is described at:
http://local.wasp.uwa.edu.au/~pbourke/dataformats/serialmouse/

but I don't know how the serial mouse is recognized as a mouse at bootup.

I haven't actually tried this, but you should be able to pipe input from a serial port directly to a file by typing something like

COPY COM1 filename.txt

at the "DOS" command line. A Ctrl-Z (hex character 0x1A, ASCII  26) coming in will close the file.

See http://chrio.org/serial/ for ideas.
