16 years agoethernet is kind of overkill to just update the NCO frequency. you can make a small Nios + JTAG UART + PIO system. add some code to interpret some input ASCII from the JTAG UART into a binary vector, and send that to the PIO. the PIO is then connected to the phase increment input of the NCO.
