Hi! I'm new to this, but already hooked on using the Papilio Pro for development. This has led to a list of interesting projects on a list - giving rise to a lot of questions. I have a LogicStart Wing, and could be using the ADC on that. But once a hacker... So I have looked for a software all-digital ADC-solution. The Xilinx site has one somewhere for the Spartan-3. There isn't much mention of it, and the data are for running it explicitly on the Spartan-3, of course. Has anyone out there tried porting the software ADC to Spartan-6/Papilio Pro? Had any succes? Wanting to share the VHDL code? The hardware ADC solution seems to work, but, really: that's no fun!!! My concrete project is a reciever for DCF77 (european time signal on 77,5 kHz). The AM modulation from this is usually decoded with little prefabricated radios. But I would like to do use phase modulation, it also contains. That should enable a faster time to lock. I do have the hardware for giving me the DCF77 signal in a 3.3 V logic format, and could do it that way around. But I'd really like to tinker with the DSP48 slices and do some filtering, thus the need for ADC functionality. I will of course need some AGC in front of the Papilio Pro, as the ADC probably wouldn't have a higher resolution than maybe 14-16 bits. Yours, etc. Peter
