Ok, trying to understand this more, i am putting a pull down resistor on GND and OE but also attaching to VCCA to enable high-impedance Hi-Z
Quote "Hi-Z (or High-Z or high impedance) refers to an output signal state in which the signal is not being driven. The signal is left open, so that another output pin (e.g. elsewhere on a bus) can drive the signal or the signal level can be determined by a passive device (typically, a pull-up resistor)."
This is to leave the comms open right? So why didnt the other guy in the youtube clip do this??
Regards
