Contradictory Pins

MATRIX7878
MATRIX7878 12 days ago

Hello,

        I am using a ZuBoard 1CG.  I plan on using the temperature sensor (I2C) and am creating my own AXI4 to control it.  The schematic and the user manual give contradictory information on which pin is which.  To whomever has used this board before: is SCL B7, or A6 and then SDA the same question.

Thank you

    Schematic would more than likely be the correct thing to follow. Also if there is a master constraints file, that would tell you as well.

    The Hardware Guide PDF I found for your board says L12P is SDA, and L12N is SCL.

    This is almost certainly the correct version, as it matches the datasheet.

    I found the master constraint file and the pins.  The user manual is what appears to be wrong, well the version I have is wrong.  Must be an old version: image
