Problems with 1-Wire DS2438 and PIC16F88

[Darrel Taylor]

Try adding this before the Read command. (after the conversion)

OWOUT DQ_Pin,1,[$CC, $B8, $00] ' Recall Memory page 0

From the datasheet ...

Recall Memory [B8hxxh]
This command recalls the stored values in EEPROM / SRAM page xxh to the scratchpad page xxh.
This command must proceed a Read SPxx command in order to read any page of memory on the DS2438.

hth,

That worked perfectly. While I figured the recall function was a bit redundant, after some more studying of the datasheet, it now makes sense. I'll post the complete code and schematic once I've completed the project.

Thanks for your help, Darrel.
