BTW, Alberto, what is the serial format? 9k6 8N1? (the o'scope is not within
reach :-)
The "user interface" is really a piece of art! Wow! I hope it will work as good
as it looks.
Hi Johan,
thanks for your nice words. Yes, the serial format is 9k6 8N1.
In the technical description I have been misleading about the use of the DDS.
Re-reading it, I see that one could infer from what I wrote that the DDS should
generate
an audio frequency. This is not of course the case, as the DDS is used to
generate
the carrier at 136kHz. The frequency values reported in that table are to be
added
to the nominal value of the carrier generated by the DDS. Sorry for the
confusion.
Another thing I forgot to say (but it could be derived from the other values) is
the throughput. Sending a nibble every (roughly) 12 seconds, means 2.5 full
characters
per minute. Not a speed champion, but it must be compared with QRSS.....
