Project GoalDevelopment and implementation of generic interface system between PC via USB2 and electronic components

Possible application• Test and evaluation of electronic components.• Verification of new electronic components according to

their Data-Sheet.• Controlling electronic component.• Perform configurations and operate of electronic

component.• sampling and Analyzing of analog signals by PC.

Background & Motivation

• Connection via USB is much more flexible and general than dedicating appointed computer or RS232 for this tasks.

• The need to verify the performance of component before implementation in a complex systems.

• Low cost FPGA evaluation board with USB gives us accessible connection to every PC.

System Interface

• Input:

– From PC :• configuration command from the user to the electronic device.

• configuration command from the user to the to the FPGA.

• analog or digital signals to operate the device.

– From electronic device :• digital signals from the system.

• Output:– display of analog signals on the PC screen.

– Configuration of devices .

– Controlling commands that operate the device.
