I have played around with the PGA450 Dev kit and it looks like it could certainly do the job we would like it to do. But I have been having troubles finding all the appropriate docs on the TI site. There seems to be multiple versions of firmware, GUI programs, and application docs strewn across the forums, but not in one centralized place with the latest and greatest of everything available. I also saw some references to some example application firmware but the only stuff I have been able to find is how to initialize the registers and a reference to an empty design note. Is there a way I can get my hands on these things to further investigate this chip?
I am also curious how we are expected to accurately process the signal that is captured in the FIFO. Is it feasible to do all the processing we need to on just the 8051 micro.
Is there a reasonable way to take the DAC output and perhaps process it only in HW? I can take care of a pulse train and threshold triggering, but the initial signal that is sent out seems to be very tricky to deal with. Is there a reliable way with the blanking timer or maybe a FIFO offset to make the DAC output only the start of the response signal?
I have a few other questions in mind as well, but maybe this isn't the best place to ask them...
Thanks
