The set of prototype boards have been produced and are currently being coded. The firmware for each is approximately 80% complete and a bootloader for in field updating is in progress. Specification can be found here.
The bootloader will enable the devices to be installed and tested/updated in-situ. This will allow the devices to be constantly used and help iron out any quirks.
A PC test suite is progressing as board functions are added. Details coming soon.
Future plans include creating a tablet control app and possibly a touchscreen embed-in-wall device.
