Nokia 3310 LCD + icons

system · December 20, 2008, 3:38pm

Hello All,

I have managed to run Nokia 3310 LCD.

thanks to info found on this forum and through google

I'm using a combo of following codes

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1142523140/15

can use most of the functions but i still have a problem with storing fonts with PROGMEM, for some odd reasons it still stores them in RAM otherwise it refuses to display anything (many of you have experienced the same problem, one can only load limited number of characters in RAM.

There is one more issue even after removing all the delays from LcdSendCmd and other places it still responds slow, may be that's because it stores everything in the RAM and updates LCD at the end of the loop.

I'm not much of a programmer and was hoping if some one could help me with the fonts PROGMEM feature and I also need to use four 16x16 icons. I'm able to display 84x48 bitmap using code found from LCD Nokia 3310 (PCD8544) Driver in WinAVR(avr-gcc) | root@fandigunawan. COuld some one be kind enough to guide me further (16x16 bitmaps stored in PROGMEM). I would highly appreciate that.

thank you for your time and efforts in advance.

i do have few brand new original Nokia 3310 LCD, not knock offs, let me know if any one needs it.

i have managed to solve FONTs issue, here is the sample code incase if anyone is interested in it. (only the font part)

static const byte FontLookup [][5] PROGMEM=
