FtdiDDS.exe is a console application created to easly set the frequency of an AD9850 RF frequency synthesizer by bit-banging SPI messages using an FT-232 (or similar) FTDI chip. This program does not require any special drivers. Just hook up the output pins of the FTDI chip (TX, RX, and CTS) to the AD9850 (clock, data, and enable, respectively) and run the command!
ftdiDDS -listlists all available FTDI devices
ftdiDDS -mhz 12.34sets frequency to 12.34 MHz
