We have some apps where we use touch buttons, either with QTouch chips, or the QTouch library directly driven by an AVR8.
Looking at the next generation of these control systems, I'd like to use some kind of "point-and-shoot" navigation like a joystick with fire button on top or a mouse.
But this app area is VERY tough on buttons and the like. Concentrated cleaning chemicals and fumes and washdown and ... Even very-well-sealed and rated industrial buttons and switches fail over time. From experience, there has not yet been found a resistive display touch that holds up.
So, does anyone have experience doing QTouch or equivalent for joystick/mouse equivalent?
Hmmm--I have another current thread about GLCD in the same environment. Perhaps the capacitive-touch like on Android would go through our polycarbonate viewing window on the enclosures?
