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)
