I hope somebody can help me with this. I need a LCD interface to move forward, and every time I try something, everything goes wrong. It's "simple", if you already know what's going on. When I try something, it's always a ton of errors or more and more files are needed. I downloaded the TWI LCD Interface app note AVR 155. Yeah, written 13 or so years ago.
I think I finally got it narrowed down to just a few errors and many warnings. One of which is "can not find -lina90.h" (which is really ina90.h, took me a while but....)
I don't know who's asking for it or why. I added the file, full path in every conceivable file (one after the other, not all at the same time), but it still will not clear the error. Something wants that file, and I'll be danged if I can tell it where it is.
It's a long story getting here, worked (or tried to) with PIC controllers for a long time on and off, but had to just give up after the last straw. Spent a lot of time and money on them and extras, but just not going to work out. I had an LCD working on an old PIC project, but they're dead in the water now, i'm not going back . I just want to kinda pick up there so I can move forward learning AVR's, but an LCD interface would make it so much easier. And I don't want to reinvent the wheel, again.
I've seen posts here suggesting other libraries (and no, I never went the Arduino route). But as I said, when I try other libraries, it's just more headaches and errors etc.... I'd like to just go with this Atmel app note as at least I have some documentation for it.
Eventually, I'd like to have it working with the popular 2wire interface LCD's you can get for couple bucks now. But just compiling error free is a start.
Thanks ahead of time.
