Clone of BeeHive Technologies's ADB I/O, a device for automation, control, and interfacing with sensors or other devices, using a PIC16F1704. See the manual for more information about ADB I/O.
Building the firmware requires Microchip MPASM, which is included with their development environment, MPLAB. Note that you must use MPLAB X version 5.35 or earlier or MPLAB 8 as later versions of MPLAB X have removed MPASM.
