Control PLL via computer
 
Hello,
I'm building a VHF receiver and I would like to include a PLL circuit to
control the VCO. I've never done it before, so I would like to use the
LMX2337 because I've a lot of doc about it. I intend to to connect it to my
computer, but I don't know to send data to it. Do you know if there are
programs to do it ? or could you help me ?

Thanks a lot.

Nat Semi has a program for doing this that you can download, called
Codeloader:

Also see
http://www.qsl.net/ke5fx/synth.html -- I've got a lot of C
control code for the Analog and National PLL chips up there, compatible
with both Win32 and Atmel.
