we are having keil MCB2140 kit.we are trying to interface LCD to
this kit which has LPC2148 as the microcontroller.The LCD&amp;#39;S supply
votage is 5v.we have given it through an external supply. 
The boards supply voltage is 3.3 volts.

Thank you for your solution.We are not giving 5v to the pins of
lpc 2148 and hence we have dropped the idea of current limiting
resistors..&lt;/p&gt;

It is obviously the datasheet for the LCD that can tell you if
3.3V is enough to be accepted as a logic high. Without information
about the LCD, this forum can not even help with reading the
datasheet.&lt;/p&gt;

&lt;p&gt;
The next thing is that not all pins on the LPC2148 are
5V-tolerant. And do you have any series resistors to limit the
currents?&lt;/p&gt;
