Nokia 3110 GLCD display driver - PCD8544

[Anobium]

Just released a Nokia 3110 GLCD display driver using the PCD8544.

The GLCD.h driver for the Nokia 3110 PCD8544 supports two modes of operation.
1 - Full support for BMP's, text (all pixels addressable) , line, box, circle etc. Requires large RAM 16f devices of 1024 bytes, or AVR or 18F. This method uses page buffering hence the need for the RAM.
2 - Support for BMP's and text only 13 * 7 characters only. No page buffering.

The command set is the standard GLCD command set. See code below and the attachment for an example.

Have fun,

Anobium

Thanks and Youtube.

• My thanks go to Hugh! He provided the method of creating a large scale RAM buffer for the 16f devices! Thank you.

• The GLCD demo, see http://youtu.be/nohcIHt6Pkw

'This program was written using the Great Cow Basic IDE for use with the PIC
'Microchio development board and a Nokia 3310 LCD. It is a nice small graphical LCD, suitable for a lot of various projects.
'The display is 3835 mm, with an active display surface of 3022 mm, and a 84*48 pixel resolution.
'The display is easy to interface, using an SPI type of communication.
'A 1-10 uF electrolytic capacitor from VOUT to GND, is the only external component needed on to display connection 7
' Display connection 1 = 3.3v
' Display connection 6 = 0v
' Display connection 7 = 4.7uf CAP
