I have a collection of LCD displays, all of which use the HD44780A controller. I'd like to use these with a PIC24H. From the data sheet, it appears that the chip should be happy with the 3.3 volt O/P of a PIC24H, since the input pins need a min of 2.2 volts. Has anyone tried this? --=20 Larry Bradley =20 Orleans (Ottawa) Canada=20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
