Custom USB device - simple circuit

Hi folks,

I need a person who knows electronics and programming, to implement a simple USB device.

- The computer will send 20-bits of binary information to the device, via USB

- The USB device will do some simple operations.

- The USB will send back 10-bits of information, also via USB

- The computer will store the 10-bits, and repeat the loop with another 20-bits string.

You are welcome to send a bid!

Please send detailed information about how you will approach the problem (e.g., components, libraries, etc). I need to know that you know what you are doing.

Please see the schematics, and contact me if you have questions.

Thanks, and I look forward to work with you!

Skills: C Programming, Electrical Engineering, Electronics, Microcontroller, PCB Layout
