I use the Melabs PicBasic Pro compiler (www.melabs.com) and do the coding in
Basic. It's really quite easy. With a 4MHz PIC and a software 'bit-banger'
routine, I'm loading my SPI-based DDS chip about 166Kbs.

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,
