  1. USB Adapter for Experiment Board Created By : Itai Heller Ofir Asulin Supervised By: Mony Orbach

  2. Project Goals • Enhancing & Expanding an existing prototype circuit built on • a wire-wrap board. • Manufacturing a printed circuit in order to broaden and • improve lab experiments, adding future implementations. • The prototype is a Communication adapter designed to • connect between a PC USB Port and a Lab Experiment boards.

  3. Existing Environment • The current device is based upon an old 8031 micro-controller with a RS-232 communication protocol. • It is necessary to advance to a more modern communication protocol in order to keep up with the PC advance, furthermore a higher data-flow rate is needed for future implementations. • The new interface must be consistent with existing environment in the lab (PC , 6 types of lab experiment devices and windows XP with VB 6.0).

  4. Characterization of system Inputs i) Type of the lab educational device: received on installation (8bit). ii) Number of lab educational device: received from device (8 bit). iii) Random address: received from the PC (3 bit). Future implementations: iv) input Port: (8 bit )

  5. Characterization of system Outputs i) PC’s approval for the connection with the device: On screen. ii) Approval for the receiving of the random address: Buzzer (1 bit). Future implementations: iii) output Port (8 bit)
