The device we need to control is a pinpad, connected via USB-serial connection. Every pin is controlled individually, sending "cryptic" strings.
I am wondering how to extend sketchpad functionality. What i need, is fixed set of switchable elements, saving their state in editing mode and replaying the state to serial port in the experiment mode. I'm quite new to the Python and don't want this project to extend to the next 150 years.
Basically, i need to know if this kind of extension is possible in Opensesame and the complexity of the entire task.
