Bit Bang FT232 to Control SPI Devices

Using C# to control individual pin states of FTDI USB-to-serial converters, I can bit-bang SPI devices! Here I demonstrate how to simulate clock, data, and chip select lines to control the AD9850 DDS (radio frequency synthesizer). I also also explore a bug that causes the output of the FT-232R to have funky timing (a problem which doesn't occur in the FT-232H).
