    4-way Mini-Joystick with center push-button; Light, temperature, and voltage (0-5 V range) sensors (light sensor no longer included due to the RoHS directive) Piezo speaker; Solder pads for user-supplied connectors: 2 8-bit I/O ports, ISP, USI, JTAG; RS232 level converter & interface (Cable and connector provided by end user)

  3. ZX Interface 2 - Wikipedia

    en.wikipedia.org/wiki/ZX_Interface_2

    The interface two comes with two joystick ports that are mapped to keyboard keys. Each joystick direction switch and the fire switch replicate a keypress on the Spectrum keyboard. This differs from the then-popular Kempston Interface , whose joystick switches are separate to the keyboard and read using a Z80 IN 31 instruction.

    The ICE is supported by the Microchip Studio IDE, as well as a command line interface (atprogram). The Atmel-ICE supports a limited implementation of the Data Gateway Interface (DGI) when debugging and programming features are not in use. The Data Gateway Interface is an interface for streaming data from a target device to the connected computer.

    The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]

    The interface devices are also defined with subclass descriptors. The subclass descriptor is used to declare a device bootable. A boot device meets a minimum adherence to a basic protocol and will be recognized by a computer's BIOS. Each USB HID interface communicates with the host using either a control pipe or an interrupt pipe.
