Using Nokia LCD

[mister_e]

Everything is plausible on any PIC, however, there's some more efficient way than other to handle Strings, and some better PIC to handle it. Oh well, It should be fun.

Steve,

i will try this weekend again everything i can do with compiling and checking the display.

When you receive yours you can also try out.

Which kind of Nokia did you order? 5110? http://www.sparkfun.com/products/10168

This kind of display does not have the Vop pin. Do i make any mistake on this stage?

How to connect display...

[mister_e]

I thought I would order that one but the other Canadian distributor I found don't have any in stock and couldn't tell me when he'll receive some more... too bad.

I found a place near who'll have the following in stock next week, I'll pick it directly at their shop.

Steve,

is the same. i like it more in blue.

The pinout are the same.

[astanapane]

on the one i have as you see there is no Vop pin. This pin as from the code i see that is connected to ground through a 4.7uf capacitor and controls the Contrast.

The point is that on the LCd i have there is no Vop pin. So how can i control the Contrast.

If anyone have the display 5110 nokia from sparkfun, could make it easier if he can upload the schematic and a simple code.

Vop is a register in extended instruction set (see page 14, Set Vop)
http://www.nxp.com/acrobat_download2.../PCD8544_1.pdf

"8.9 Set VOP value" (on page 16) describes how to calculate setting value.

Contrast is set in "Lcd_Init" section in LCD_3310 -file.

Lcd_Data= $c8: GOSUB Lcd_SendByte       ' SET LCD Vop (CONTRAST)

Here it seems to be $c8, with some older I have to use $d1 and other newer might need $bf. Try to change the value and check which is best with your display.
