I try to interface LCD with Tiva C Series kit. its an error like this
lcd123.c(9): error: #5: cannot open source input file "hw_memmap.h": No such file or directory
what shell i do...
If you have missplaced your keys, don't you then spend some time looking for them?
So - have you spent any time looking for any file "hw_memmap.h"? And where have you looked? And where did you get the file "lcd123.c"?
Find the file, and it's position relative to your other source, and either get a copy of the file, or set the "include paths" used by the compiler so it may find it when you #include it.
