NHD-C12865AR-FSW-GBW or ST7565R COG display
Hello,
Has anyone had success with Adafruit's Arduino library for the ST7565R based graphics display? I have a partially working display but I'm have issues with pixels sticking on and not being able to clear them until power cycled. I'm starting to think I will need to write a driver from scratch.
I'm using the NHD-C12865AR-FSW-GBW display but I am willing to switch to a more software supported display model as long as the price is similar or less, life cycle outlook is good, and second sources are available. The company would probably choose cheap over a color option.

Hello,
Sorry to hear you are having this issue, are the pixels always in the same location or are they random?
Unfortunately, we have not tested Adafruit's code.
One suggestion would be to add more delay time after each of the commands in the initialization code in order to allow the display controller to fully process each command before writing data.
Another suggestion would be implement a buffer clear routine to prevent the stuck pixels.
Please let me know if this is helpful.0
