I have a 18F2520 connected to two spi devices. When I add a DEFINE like "DEFINE SHIFT_PAUSEUS 200" I can get spi device A to work, but not SPI device B. When I remark the DEFINE statement out, I can get SPI device B to work, but not A. How do I solve this delimma?

I have been trying to get these two devices to "talk" at the same time for a couple of weeks now, but they both seem to like a different clock frequency. Is there a way in pbp to allow this?

Okay then can someone answer me this. Why is it a device will work fine at default shift clock (50kHz) and not work fine at 200 uS slower?

Nevermind. I found an older more in depth datasheet for the device that states the SCLK high can be no longer than 50nS.
