FPGA are great devices for tinkerers. If you are interested in electronics design, computing and retro games, come join the fun. Here are some projects and modules I created for helping with your FPGA projects.

Memory

• SDRAM controller for Tang Nano 20K - A simple SDRAM controller with example code.
• DDR3 controller for Tang Primer 20K - A DDR3 controller for Tang Primer 20K, used in NESTang 0.4. DDR memory is much more complex than SDRAM. Make sure you try SDRAM before you tackle DDR.

Interfaces

• SNES gamepad module - This is a quick demo of reading the SNES controller with Verilog (Tang Primer 25K).
• Usb_hid_host - An easy-to-use USB mouse, keyboard and gamepad interface implemented completely in Verilog, with examples for Tang Nano 20K, Primer 25K, IceBreaker, IceSugar-Pro and other boards.
