The paying customers are taken care of for a while,
so it's time to update the blog. I want to test some DSP on the
FPGA (filters, RF signal modulation/demodulation, etc)., so I need
A/D and D/A capability. I could buy a board, but it's more fun to
build my own. So I settled on a quad, 8-bit, 100MHz board that
interfaces to the Xilinx or Digilent board via the 100-pin FX/2
connector. The block diagram shows one of the 4 channels. As a
test, I'm capturing a signal and displaying it on the VGA output.
The signal is looking reasonable. More details on my website:
