#6 HD44780 on C.H.I.P.

[Antonio Petricca]

Hi, I need to use LCDProc with a HD44780 display as 4 bit mode on a CHIP board (http://getchip.com).

By the instructions provided by this link https://bbs.nextthing.co/t/lcdproc-with-20-character-by-4-line-lcd/8789/30?u=daredevil73 I configured it, but I got the error explained here https://bbs.nextthing.co/t/lcdproc-with-20-character-by-4-line-lcd/8789/31?u=daredevil73 :

Could you help me please?

Could I modify the HD44780 driver and let it consider C.H.I.P. as a Raspberry Pi?

I just wrote a new connectivity module, but I cannot yet get it working (maybe a wiring issue)...

My driver is working!!!

How can I submit it for the next LCDProc release?
