nokia pcf8813 driver
I am also having the same problem as zinahe. My solution to the problem is by setting the cursor to start at Y=1(bank 1) and adding vertical offset.
I think the new nokia 3310 uses ST7548T or similar LCD driver by Sitronix.
I tried to design a common collector using 2n3904 to get a current gain for at least 125mA to drive a speaker.
I tried but my output waveform is not what i expected to get.(it looks like its rectificed)
Anybody can help me? :cry:
