Tool/software: Code Composer Studio
Hello everyone,
I'm working on scrolling text on my msp430fr6989 launchpad. It's returning an error these errors:
#10010 null: errors encountered during linking; "LCD_2.out" not built LCD_2 C/C++ Problem
<a href="processors.wiki.ti.com/.../10234"> null: unresolved symbols remain LCD_2 C/C++ Problem
gmake: *** [all] Error 2 LCD C/C++ Problem
gmake[1]: *** [LCD.out] Error 1 LCD C/C++ Problem
unresolved symbol mode, first referenced in ./main.obj LCD C/C++ Problem
These 5 errors doesn't point to any lines on code or neither they can be seen on header files I'm using. When I try to debug anyway it returns me an error of :
Encountered a problem loading file: C:\....\CCSWorkspace\LCD\Debug\LCD.out
The file missing is should be a Pspice model file.
I've attached my code files which are not much different than Outofthebox code examples. Just changed it's Initialization part according to my understanding. Thank you.
