Nokia 3310 scope project

Nokia 3310 graphical display seems to be very popular among embedded hobbyists. Probably because of it’s availability, lots of examples over the internet and simplicity of interfacing. Wichit Sirichote has developed simple scope application by using his project 8051SBC board.

Interfacing of display is very simple as it uses serial interface. The only thing you should take care when using 5V logic is to reduce LCD voltage to 3V level. This can be simply done by using two general purpose diodes connected in series. This provides approximately 1.4V drop. Source code is available for your experiments. Also you can see live action of this simple scope in this video. Of course this scope can’t assure you proper characteristics but this example gives you great info about interfacing 3310 LCD. [via]
