Title: NHD-C160100DiZ-FSW-FBW - random pixel after init
Post by: iz7crx on February 08, 2016, 05:59:35 AM
I'm using init sequence reported on datasheet but when display comes on i see random pixel on it: is it a normal behaviour?

Regards,
Dario

Would you be able to post a picture of what you are seeing?

This is not normal,

Have you tried to clear the display?

Clearing by setting pixel to 0 works correctly, but random pixels appear after init.

I think it is related to reset line shared with MCU one: i'm trying to have its own reset line.
