Jim, When you have the logic analyzer connected to the PIC pins, are you seeing consistent data between transfers meaning reading to reading? 15 feet is quite a ways for an un-buffered SPI bus. The...

Re: Reading DS1620 (SPI Temperature) from 18F46k22 Micro at 16MHz
Jim, Looking at the data sheet, I would change the "SHIFTIN TDAT, TCLK, LSBPRE, [tempIn\9]" statement to "SHIFTIN TDAT, TCLK, LSBPOST, [tempIn\9]" According to the data sheet, the data is valid until...
Re: Reading DS1620 (SPI Temperature) from 18F46k22 Micro at 16MHz
Jim, I have converted much of my code from old projects using the 18F4620 to 18F46K22's. I have a few questions. What are you doing with the RESET line to the part? Are you looking at the DONE bit...
