    I have a Zeroplus LogicCube. I have installed a 1wire protocol analyzer but I can't seem to get it to work.

    I am using a PIC18F14K22 running at 16MHZ. I am connecting to a DS1820 temperature sensor.

    So far I am just sending a

    to repeatedly send a reset pulse, a READ_COMMAND_DS2411 to the sensor to get it's serial number. That appears to be successful.

    I wrote a loop to repeatedly send the reset, the READ_COMMAND_DS2411 and the read so I can capture some data on the LA.

    I can see the transitions but the protocol analyzer is not interpreting the data correctly.

    I am a total newbie at this. And would need some real "hand holding" I also realize this is a long shot but can anyone help?

    I tried contacting Zeroplus but all tech support is in Taiwan. It is painful to say the least. Their help files are almost useless. All they really do is to repeat the various settings of the software but never explain their purpose or use.
