EmonGLCD Screen Stripes / Dark Spots (Solved)

Submitted by Guest on Sat, 27/10/2012 - 14:46

Hi everybody,

I have assembled my emonGLCD for some time now. but i always notices some stripes on the screen that i cannot see in nobody´s screenshots posted over the internet.

I thought that it was due to fast screen refresh, some noise, etc. but i´ve noticed today, when it crashed (testing) that the screen dark spots / stripes where there.

Can anyone tell if this is normal? look at the pictures below. The worst area is the top right one.

 

From OpenEnergyMonitor Screenshots

Thank you all.

You can try to change the line

glcd.begin(0x20);  Line 120 Ish

This is the contrast of the LCD iv got mine set to 18 or 19 as that looked better to me.. Have a play around.. 20 Is the max by the way.
