Folks,
Looking for a simple control interface. It should ideally be a module that can be screwed or snapped into a front panel cutout and contain this:
- A backlit LCD/TFT/whatever monitor of 1.5" or 2" square. Can also be another rectangular form factor, just not as big as a smart phone if possible.
- Addressable via SPI or similar. Ideally alphanumeric for fast and lean data transfer but with an option to load graphics. The latter isn't a requirement. A chance to load foreign character sets would be nice.
- Integrated softkeys, maybe three per side or so, that can also be read via the same or another serial bus connection. A touch screen with a somewhat larger display could also work, then the display could be almost the size of older generation smart phones.
- Washable, so ideally it should be overlay (foil) keys where fluids cannot seep inside and the screen should be sealed. Hospital grade cleaning agents will be used on it.
Cost is not so important, it's for prototyping at first. We could build all this ourselves but there's so much packaging involved and I could imagine there already is something out there. I just don't know which vendors to look for becasue I never needed anything like this. A pointer to a vendor would also be nice.
