Re: [lcd4linux] Is it possible to use LCD4Linux with a HD44780-compatible LCD, which is attached to the GPIO pins of a Raspberry Pi?

[Michael R. <mi...@re...>]

Hello Christian,

as lcd4linux is a lot older than raspberry, I don't think that it will work, at least not out-of-the-box.

back in the "good old days" the only GPIO-like thing on a PC used to be the parallel port, and thats what a low-level 
driver exists for (drv_generic_parport), which uses either extremely old school io instructions, or ppdev.

As I have absolutely no idea how GPIOs are controlled on a raspberyy, I cannot advice you how to implement it.

maybe using some kind of i2c-to-parallel chip could work, too.



regards, Michael
