Problem with Sparkfun Display LCD-11062 (Nokia 6100-Display)

Hi everyone!

A few days ago I purchased one of these displays: https://www.sparkfun.com/products/11062.

I've connected my Sparkfun LCD 6100 as it's described in the description from https://mbed.org/cookbook/Nokia-LCD. The Display seems to display something, but I hardly can't read it. Only in this angle you can read a little bit, but the background color is missing. /media/uploads/MasterSheet/img_20131125_160430.jpg

When I start up my program, the display work for a couple of milliseconds properly, but then you don't see a thing. If you want to look at it normally you cant read anything. /media/uploads/MasterSheet/dsc_0786.jpg

At first I thought, it might be my contrast, but when I've tried to change it in the library, nothing happened. I also tried to change my contrast to '-53' like it's recommended by the datatsheet of Sparkfun. Without success. (http://dlnmh9ip6v2uc.cloudfront.net/datasheets/BreakoutBoards/ColorLCDAppNote.pdf)

Is it possible that my display is broken? I hope someone can help me. Does anyone have the same Problem?

Hello Christoph,

sorry for not having a suitable solution for this problem, but I got the same effects. I'm not using the sparkfun breakout, but the "naked" display, bought on ebay, a few days ago. I'm using Simon's Hello World code with the "LCD6100" option (other ones don't work; "6610" gives scrambled characters).

If you found a solution to this I'd be glad to read you again.

Michael

Hi Christoph,

I had a similar problem which is what led me to your post hoping to find an answer. After a bit of experimentation I got the example at http://www.sparkfun.com/datasheets/LCD/SFE_lcd_driver_c.zip working by changing the setting for the first parameter of DISPCTL from 0x00 to 0x0c.

Hope that helps!

Awesome! That helped me out too! I've published my own fork of the MBED library that includes all known fixes including this one: http://mbed.org/users/plskeggs/code/NokiaLCDex/.
