16 character display module and 4-line HD44780 display compatibility


#1

A few months ago I salvaged what I think are some 4 line HD44780 displays and had grand plans of repurposing them with some HD44780 Gadgeteer modules, but sadly it didn’t survive the recent modulegeddon. The version with an attached display is still available though, so I was wondering if it would still play nicely with a third party 4-line LCD display?

@ Bogus - the integrated version (https://www.ghielectronics.com/catalog/product/395) is just that. I’d take a look at the schematic of the discontinued product (http://www.ghielectronics.com/downloads/schematic/HD44780_Module_SCH.pdf) and play with an extender to achieve what you need. If you’re using 4.3 you’ll need to get the discontinued SDK too. There’s a good few posts on here that discuss doing that.
