Thank you Nav,

ice,

the code example is tested and working.

There must be something wrong in your Hardware.

could you post your schematic?

Hello friends, excuseme for my english, it's not my language...

It's so interesting to drive nokia LCD's, but i have questions:

1) The nokia LCD has an internal controller, or are you controlling directly the crystal display???
2) If in the fact it have a controller, where can i find information about how to drive my LCD. I have LCDs of nokia 8260, nokia 5120, nokia 6120... there are TDMA cell phones and I don't know what type of LCD they have.

Help me please

Thanks

ice,

please doublecheck your hardware setup.

I have only a small 100nF cap on Pin 7 (VOUT)
and Pin 5 (SCE) is directly tied to GND.

Nav,
I got ur code to work on a 873A.. i can move the cursor position to any place on the screen ..however,the digits which have to be displaying are all boxed..but i can notice the numbers changing...also the display keeps flickering..
I tried changing the init value in ur code too...but i cant seem to find the optimal ones..

Thanks alot

Thanks so much for your help, but I need more help...

I'm talking about the specific models of LCDs that you can found in nokia TDMA cell phones: Nokia 8260,Nokia 5120, Nokia 3320...

I seen the photos of the projects and i can see some diferences with my own LCDs, so my question is if your LCDs have an integrated controller or are you driving directly the crystal display, without an LCD's internal controller that can have communication with the external PIC micro?

Thanks again...
