Nokia LCD

Like every scuba diver (I have CMAS P1 qualifications) I wanted to have my own diving computer. Unfortunately I couldn’t afford one. So I decided to make one. I wanted to use LCD from Nokia 3310 mobile phone (LCD controller Philips PCD 8544, only 300 uA),  AVR microcontroller, Honeywell pressure sensor 26PCDFA2G. Assembler source code can be found here.


Prototype – ATMega 16, NOKIA 3010 LCD, pressure sensor.
Time in water, current pressure, maximum pressure.
LCD pin-out.
