I’ve started playing with the Nokia 3310 LCD. It’s similar to the LCD I used in my watch project<\/a> but is black and white only. It’s a little clearer to read, and hopefully consumes less power.<\/p>\n

I’d ordered a pack of 7 nokia 3310 LCDs from the internet. However after I disassembled the nokia packaging I noticed there were actually 3 different LCD types present:<\/p>\n

\"\"<\/a><\/p>\n

One didn’t have metal contacts, only glass ones. The other, with the smaller IC I spent a long time fiddling with, and couldn’t get anything to display on. It could be that my wiring was dodgy but I’ve also known LCDs for the same phone to behave differently. Nokia have been known to use different LCDs in their phones and include detection logic to figure out how to drive it. Anyway… the LCD with the larger controller worked, and if you are considering using a 3310 display I’d recommend you try and find this type.<\/p>\n

I used the code from here<\/a> as my basis. I removed a lot of his project specific logic and added my own simple test code.<\/p>\n

Here’s the setup:<\/p>\n

\"\"<\/a><\/p>\n

That cap does seem to be required. The 3510i LCD works without one, I might do some more experimentation with this.<\/p>\n

And here’s what the code outputs:<\/p>\n

\"\"<\/a><\/p>\n

And here’s the code! Again, largely due to TopHatHacker, with some trimming down and a few modifications:<\/p>\n
