FPGA examples on Scarab Hardware miniSpartan3 board. All include ISE project files.
LED counter, with inputs from the switches to control 'speed'.
DVID output from the HDMI port. Uses TMDS Encoders from Michael Field, as well as a modified version of his VGA signal generator.
Use the switches to change the output: All on is a test pattern, with the rest displaying all red, green and blue. LEDs reference the RGB setting.
Uses Xilinx-provided Spartan3 UART modules and implements loopback rx/tx via the lines connected to port B of the FTDI USB chip. Can connect to the COMx port via a serial terminal when the miniSpartan3 is connected over USB. Switches determine echo or a '@' reply per-byte.
