Hi…
this is my first microcontroller based project..
i am done with the hardware part.
i used AT89c51 rd2, AT89v51, AT89s51 and also AT89v55
but its not working on any of it.
when i apply the voltage, the backlight of lcd turns on and nothing else happens. The same happens even without connecting the microcontroller.
what can be the possible error.
the size of hex file is 6kb. is that the problem??
or maybe the delay problem??
plz reply asap!!! its urgent
thank you
