Graphic LCDs / NHD-C12864WC-FSW-FBW-3V3-M random pixels at init
« on: November 27, 2016, 09:01:06 AM »

I am using a  NHD-C12864WC-FSW-FBW-3V3-M graphic display and at the initialization (which I followed the datasheet to do) , there are random pixels appearing a little bit everywhere on the screen. I am not sure for what reason this would happen, so I figure maybe someone has had this issue before?

And we can also see on the lcd that the lines where the pixels are printed, the contrast seems different as well?

What am I doing wrong or am I missing something?

Thank you for any help ^_^

Here is a picture of it :

In the light of a recent project, I was trying to adjust the backlight brightness of a NHD-0420D3Z-FL-GBW display through coding , but even with the commands specified in the datasheet, I am unable to change the brightness.  Here is the section that adjusts it in my code :


. . .

Anyone have any idea's as to why it won't change? I am stumped. I did manage to make it change before, and when that happened I was not able to change it back again.
