Use pd-l2ork. It comes with disis_gpio and disis_spi (for analog inputs, like the ones found on Lots-of-Pots shield) which should cover all your needs. It includes both hardware and software PWM, as well as all the usual I/O GPIO stuff.

Best,

Ico

Hello,

an alternative is about using a python script that communicate with PureData through OSC, it can be done with abstractions on pd side and examples provided by python users.
