Hi!
i am facing some problem, by interfacing a Nokia 3310 LCD with AT89C51 MCU. what i am doing is supplying the LCD +V from the 7805 Regulator and directly connecting it pins (SPI interface) to the controller, i have properly connected the pins and double checked it, i have also simulated the code in Proteus VSM , its working, May be i am missing some trick in real time, so can some Guru give me some idea so that i can run it, Thanks for the concern to read my message, Regards Ahmad Kamal Nasir.
Have you read the manual of 3310? In the version I have,it's supply is 2.7-3.3V.
yeah, you are right guru. after supply modifications the problem has been solved thanks any way!
So lucky you! I have destroyed serval 3.3V devices by connecting them to 5V...
