Driver for LCDs using Hitachi HD44780U controller

Post by jciern » Fri Oct 12, 2018 5:20 pm

Just a simple inquiry:

Does anyone know if a driver library exists to interface a pyboard to an LCD using Hitachi HD44780U controller?

I've attempted to write one but have encountered issues i.e. garbled text displayed. I think this may be due to timing issues which might take some time for me to resolve.

In the meantime I'd like to use an existing driver, should one exist.

Search for HDD44780.

It's a popular controller with a few driver implementations. These forum posts (1, 2) should help.
