problem with LCD
hi..
i am using analog and µc board separately.
i am giving my analog inputs to ADC of µc.
µc is interfaced with a LCD display.
Power supply to both boards is from different sources(transformers).
when i use both boards independently they work.
as soon as i connect both boards i.e. by giving the inputs to µc board and shorting bothe grounds my LCD shows up with boxes only..
after switching ON-OFF continuously my LCD shows output.
i am not able to find out the problem..
please help me soon..
its urgent...
thnx in advance
