Hi Chuck: please advise what need to be done to interface the UBW with SRLX8.3. The UBW runs on +5V and the Si570 on +3.3V. Is it advisable to connect the SDA, SCL pins from the UBW directly to the corresponding pins of SRLX8.3 PIC socket? Is a level translator like the one in the WB6DHW Si570 board needed?
I have also made some minor additions to Joe Hopster's firmware - adding a subset of the Kenwood CAT interface so that the UBW emulates a Kenwood TS-2000. The CAT interface code works on my UBW <-> DDS60 hardware but it is not tested on UBW <-> Si570 yet as I haven't built the hardware :) I will incorporate your additions and post the source after completing the hardware and testing the firmware.
