SPC to PIC

[Macgman2000]

Thanks! The information is enlightening....but Now I have more questions than when I started...hahaha.

Like..

1). PBPro SHIFTIN does not work for > 50khz clock. The digital calipers output a clock of 90khz. How do I set up a synchronous serial input given those requirements?

2). I am confused as to the actual output data rate of the calipers. The project deals with interfacing to a PC so my conclusion is that the 9600bps is to the PC? or am I incorrect?

HELP!!!!!

Best Regards,

Nick,

PBPro SHIFTIN does not work for > 50khz clock. The digital calipers output a clock of 90khz. How do I set up a synchronous serial input given those requirements?

as of the information I have gathered so far the caliper interface operates @ 90kHz.

And it atcs as SPI-Master, so SHIFTIN wouldn't work, as it claims to be Master, not Slave
(The Caliper provides the clock, not the PIC)

You will have to write your own SPI-Slave Routines.

I am confused as to the actual output data rate of the calipers. The project deals with interfacing to a PC so my conclusion is that the 9600bps is to the PC? or am I incorrect?

That is absolutely correct!
