Re: [AVR-Chat] LCD and I2c; LCD drives man insane...

2004-05-07 by John Johnson

Okay, I finally got all the egg off my face, and thought I would post 
the solution in case anyone else searches the archives.
My 4 data lines were connected to DB0-DB3, instead of DB4-DB7. After 
correcting that and working on some timing challenges, it's working 
great. Thanks for all  the replies!

Thanks for the ref. to your lib too, I'll check it out.

Regards,
   JJ

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
