>Marullo looks like you have a solution. Even a choice of displays.
Paul and others,
thanks but that was not exactly what I was searching for. You did give
me very good suggestions but my problem is a little more subtle.
I just need the simplest chip incarnation that would provide me with
frequency out on a serial port.
To cut a long story short, this is what I would like to do:
http://home.comcast.net/~tinkyr/736/Ham%20Radio%20Deluxe%20and%20the%20FT-736.htm
but for the FT-102. The FT-102 is a radio with analog VFO, almost no
digital stuff in it, latest and greatest hybrid Yaesu radio with PA
using 3 x 6146B.
I need to emulate a radio from the Ham Radio Deluxe perspective, so I
need to know which is the frequency and the band on which the radio is.
Communication will be unidirectional from the radio to the computer, or
even if I would receive commands from the computer there is no way I
could change the band and/or frequency of the radio, nor I would (tube
finals, need retune).
I want to move the knobs on the radio, and the computer should track
what I do. The computer should never try to command the radio.
This is just for tracking purposes (yeah, LoTW coherence when
registering contacts).
I was searching a chip because I feel at ease using Lazarus, and I am
playing with a nice Raspberry PI (PITFT), seems silly to add an Arduino,
even though Raspberry could see it through USB as serial.
So far:
- cheapest is Cheapduino
- most poweful is Teensy (3.1 version goes up to 60MHz) but I don't know
how to program it. Prolly it has enough horsepower/pins to capture
frequency/band selector and emulate everything so no PI needed. Still I
don't like the idea to develop in C while having Lazarus on a PI for
35bucks.
Do you know any precooked chip able to go at 8MHz minimum, better up to
30MHz with 10Hz resolution and simply shove the reading down to a
ttl/3.3v serial interface?
Please feel free to answer privately, at this point it is not that time
nuts question anymore, thanks.
