Question

I have several 450 element character arrays (storing bitmap data to display on lcd screens.) I would like to put them under a header file and #define them, but I keep getting compilation errors. How would I do this in C?

#define numbers[450] {0, 1,etc...}

#define numbers {0, 1, etc...}

#define numbers[450] then set the numbers later

and many more…

Well… you certainly don’t need to use a define. Just add them into the header as const, static arrays.

/* prevents multiple, redundant includes */
/* make sure to use a symbol that is fairly sure to be unique */
#ifndef TEST_H
#define TEST_H

/* your image data */
const char image[] = { 1, 2, 3, 4, ... };

#endif

Also, if you want help on a compilation error then you should post your code.
