I'm about to deploy the first generation of a control panel for the lights in my church's sanctuary, built for the 770. It's a python app that uses Art-Net to drive a DMX-512 converter that runs the dimmers, and is designed to be multi-station. So far it's working fairly well in development, except for the fact that the redraw routines are taking too long. I know how to fix that to some degree, so it's not a major concern. However, what is a definite concern is that the touch sensitivity could create a lot of frustrated users as it stands. While I haven't mounted one to the wall yet, using full-finger presses seems to be somewhat hit & miss. I'm not really in a position to tell everyone using it to "use your fingernail". What kind of controls (if any) are available to tweak the sensitivity of the touch screen in order to make it more amenable to intentional fat-fingering? I don't really care in this application how rough the resulting mouse events are, as the interface is designed to leave enough space between buttons so it'd be pretty hard to get badly wrong. Am I going to have to look at using the pressure data directly, as per HOWTO UseTouchscreenPressureData ? That would complicate matters since I'm writing in Python to avoid having to build the entire compilation environment... TIA, Omega aka Erik Walthinsen omega at vcolo.com omega at temple-baptist.com
