I have got a 5v LCD module that i need to adopt for 3.3v of operation. Could anyone suggest me anything?
I have a board which has a 3.3v IC so I have to keep my supply voltage 3.3v The LCD goes blank at this voltage. One way is that I put a separate voltage source for the LCD. But this shall mean 3.3v of IO signals. Is this okay? Do I need to place a level shifter on all IO pins?
Please don't ask me purchase a 3.3v module I cant find one in the local store and shall not be allowed to order one from Digikey or some such online store
Thanks in advance.
