I was originally declaring my variable passed to lcd_puts as

This, after discovering to my surprise that lcd_puts wants signed chars.
Recently, I've converted to the portable typedefs as
unit8_t and int8_t
Now, whichever of those I use, I get a warning:
warning: pointer targets in passing argument 1 of 'lcd_puts' differ in
signedness
According to stdint.h, int8_t is supposed to be signed, which I
understand to be the same as char.
So what am I missing?
And as a secondary question, why does lcd_puts want signed data? Seems
nonsensical to me..
I know what *I* am missing - the source code! How is anyone supposed to
help you with your problem until you post the actual compilable code
snippet? We need a compilable code sample which demonstrates the
problem, along with the compiler flags you used and also the compiler
version you used. Getting a warning for int8_t but not for "signed
char" is not expected behaviour, and I think many people (as well as
you) would be interested to find out if that is really the case, and if
so, if there is some strange compiler issue. But we need the code so
that other people can test this.
I had hoped that after being asked so many times to post code snippets
in previous threads, that you would have thought of this yourself. I'm
happy to spend time helping out (when I have the chance), but I'm not
fond of repeating myself.
mvh.,
David
