#146646 - Pullups?
Responding to: ???'s previous message

Mostly zeros read as ones.

Could be the that the device is not pulling hard enough to get the line down to the zero level? Which, in turn, could be because your pullup is too "strong" - so the device can't "overcome" it when it needs to assert a zero?

Is your delay between bits sufficient?
