OLEDs / nhd-0216cw-ar3 - locks up
« on: February 13, 2015, 03:07:28 PM »
Interfacing to the display using i2c at 3.3V with 4.7K pullups.
I have been able to send both lines multiple times but
randomly the i2c bus freezes. Seems as the data line is being pulled low.
happens in middle of a command or data transfer. 
I have tried 10KHz and 400KHz clock rate transfers both have the issue.

Any thoughts?

Cheers
T
