What is the purpose of the expansion port ?
The expansion port allows to connect additional controls to the Bitstream 3X. In the future, Wave Idea will propose different low cost hardware (to be connected to this expansion port). These expansion modules will be fully managed by the Bitstream 3X and therefore seen as additional potentiometers for instance. Depending on the customer requirements, Wave Idea will decide the type of controls to be found on expansion modules. (joysticks, touchpad, sliders, buttons, ribbon, …) The format of the Bitstream 3X expansion port is proprietary, there is no documentation available that may help you to build your own expansion module.
