OLEDs / NHD-0216CW-AB3 dots underneath characters
« on: November 19, 2015, 10:26:39 AM »
I've got this screen set up using SPI at 3.3V an it seems to be working other than I get a single row of dim pixels underneath the characters. If I stop writing to the display the dots go away and just show the static characters. As the characters change I get a different arrangement of dim dots.

I am writing to the display every 40mS and showing a changing value.

I have tried slowing the clock down to 500Khz but no effect. My SPI timings seem to match the US2066 data sheet.

Any suggestions to fix this would be gratefully received.
