The nice thing about the synchronous serial interface is that the
transmitter can clock data out at whatever speed it wants to -- so you can
bit-bang with the PIC with no problem.

You may want to check if your flavor of PIC has an SPI port -- they're
designed to implement just that kind of interface.

Greetings!

I would like to know if anyone has been successful developing an
interface for 3 wire serial feed to a PLL: (Clock, data, latch enable)
using a PIC or similar devices. I presently use my computer to control
my VFO. Software is the Code Loader from National.com It works very
well. The speed of the Clock/Data appears to be high and I am wondering
if a PIC could work at the same speed and/or produce the same rise
time.!
If email is sent, please remove the xxx,
