4's the limit, at least for now?
Not sure how to display 6 lines instead of 4 but this is a BIG display from eBay...worked for me...
Off the top of my head, there is 1608 & 2008. There hard to find, there essentially 2 controllers , the 6 line display undoubtedly has 2 controllers if itsa HD44780.The HD44780 can be daisied upto 4, giving 16 lines, but nobody makes them as there is no demand. The library for the HD44780 can do up to 8 lines as it sees both chips as one. So 6 lines is very doable.If anyone ever finds some 1608, 2008 or 4008's i would like to know!
