A prototyping apparatus includes a housing, a microcontroller within the housing, a user interface on an exterior surface of the housing for interaction between a user and the microcontroller, and a first connector, exposed in a first slot in the housing, having a first plurality of pins for accepting a first external component. Via the user interface, the microcontroller presents a first plurality of configuration choices for the first plurality of pins, and accepts user selections from among the first plurality of choices. The prototyping apparatus may further include a second connector exposed in a first slot in the housing, having a second plurality of pins for accepting a second external component, in which case, via the user interface, the microcontroller presents a second plurality of configuration choices for the second plurality of pins, and accepts user selections from among the second plurality of configuration choices.

Prototyping apparatus with configurable pins and corresponding methods

A prototyping apparatus includes a housing, a connector on the housing for accepting a component, a microcontroller within the housing interacting with the component where the microcontroller has program memory, a user interface on an exterior surface of the housing for interaction between a user and the apparatus, a connection to a source of upgrade software, and programming circuitry within the housing for causing the microcontroller to enter an upgrade mode. The prototyping apparatus may further include a processor in communication with the microcontroller and the user interface, a device driver running on the processor for actuating the programming circuitry responsive to the command received through the user interface. The prototyping apparatus may include circuitry for generating a voltage that is higher than an operating voltage of the prototyping apparatus, and may further include level-shifting circuitry for shifting signals that are at the operating voltage to the higher voltage.

Prototyping apparatus with built-in programming facility and corresponding methods

A system and method for controlling the power of an electronic reader device is provided. The system for controlling the power of an electronic reader device may comprise a computing apparatus that may receive a command from a host system to change the power state a power controller. The system may also comprise a computing apparatus that may adjust the power state of the power controller by using one or more registers. The system may further comprise a computing apparatus that may adjust the power of one or more power supplies. The system may additionally comprise a computing apparatus that may instruct a display controller to perform an operation based on the change of the power state of the power controller.
