Nokia LCD 3510 Interface with PIC18F

October 3rd, 2011 by Fábio Souza | In: Arduino, Electronics, PIC, Programming

When a mobile phone crashes in terms of software and even some hardware There are parts that can be used for experiments or for projects, in particular the LCD's, saving yourself some money.

The aim is to use an LCD from a Nokia 3510 connected to a microcontroller for information visualization, as done in previous experience, in a Nokia LCD 1100.

It is assumed that this controller is prepared both for the LCD 3510 ( screen with shades of gray), as well as the 3510i (the colors), According to this site.

Look for the welds made in contacts. It is a meticulous and work something that quite calm, as well as a low-power iron (14W) so as not to damage the contacts and the plastic membrane.

August 5th, 2011 by Fábio Souza | In: Blog, Electronics, PIC

From a nokia 1100 damaged, but with functional LCD, It used a PIC18F2520 to process text and variables display, as the temperature. Since the communication with the LCD is slow and series, It used the internal 8 MHz crystal to command the screen by PIC.


The screen seems transparent and has a low consumption (10mA), same with brightness. With this, You can reuse functional screens of mobile phones that were cancelled.

The main routines are in this site, having been changed to the PIC above.
