Hello all Can I interface a LCD unit running at 5Volts with a PIC running at 3.3v. I read in the manual MAX "Voltage on all other pins with respect to VSS ..-0.3V to VDD + 0.3V" Which to me sounds like no but your opinions are appreciated Tim -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
