Hello Guys!!!
I am using a 2*16 lcd module. My college sir told me that instead of connecting Vcc to pin no.2(Vcc) of lcd & using a pot between Vcc & gnd connecting its var. pin to pin no. 3(Vee) of lcd, connect directly Vcc to Vee of lcd & leave pin no. 2 of lcd open. He says, by these connections lcd will work fine. Is it correct?

hi,
Some LCD's work with Vcontrast pin at 0V, but I would recommend a 10K pot from +5V to 0V with the wiper to Vcontrast.
This way you can set the optimum contrast for the LCD
Hello Again!!!
I am using EAGLE for creating the layout. But, there are many overlaps in lcd connections when I connected lcd in standard fashion i.e. P0(0-7) to D(0-7) of lcd & P2(5,6,7) to RS,R/W,EN resp.. Instead if I connect P2(7-0) to D(0-7) & other 3 to P0 pins will it work fine?
While writing program I will take care that P2.7 to P2.0 are D0 to D7 respectively.
Latter one simplifies the problem.
Please help.
