To allow for testing our general purpose input device, the AXIOM Remote, in an automated way, we designed an interface (AXIOM Beta shield and Add-On PCB) which allows to press buttons and turn dials on the AXIOM Remote from the AXIOM Beta. The shield is connected to one of the routing fabric FPGAs so gateware needs to be developed.

Goals:

• Implement and test the HDL to press buttons and turn dials (encoder) via simple commands.
• Add advanced actions for testing (button bounce, encoder skipping, etc)
• Design a test framework (Python or C) which allows to run automated tests.

Prerequisites:

• Basic FPGA Know-How
• Basic Electronics Know-How

Language Skills:

• HDL (VHDL, Verilog, nMigen)
• Python or C
