Thank you purchasing ActiveWire USB board.
This referece contains deep inside information of ActiveWire USB hardware.
Please refer to the ActiveWire USB Software Reference for
information about ActiveWire software.
Caution!
It is strongly suggested to use extreme precaution of electrostatic discharge when
handling the board.
Touch conductive grounded surface, such as exposed chassis with power code plugged in to the grounded AC outlet, to dischage your body before touching the board.
Handle at the edge of the board. Do not touch directly to the pins of components on the board.
Keep the board in an ESD safe bag when not in use.
- Simple 16bits programmable Input/Output pins
When the board is used alone with standard firmware and driver, 16 bits of I/O can be used to interface with external circuit. Each I/O is programmable to input(default) or output.
- Addressable 8bits Data Input/Output Bus (ActiveBus)
When the board is used with ActiveWire Add-on boards, the board should have a protocol implemented to communicate with multiple boards connected to the same headers.
ActiveBus is designed as a simple 8bits Data/Address multiplexed bus architecture. See following section, 5. ActiveBus, for more detail.
Following tables show pin layout of each headers.
