Hello,
I have connected (corerctly I beleive) a DS1621 to the 18F2550...
I included the DS1621.c in mine program... but keep reading the same wrong value (0x1E)... When looking whith the scoop I see that there is communication between the DS1621 and the pic but why o why I keep on reading these strange value???
Include the main.. DS1621.c is like the driver file from CCS..
