I received the error above when I compile this. Please help me to fix this. Thanks

drawBitmap(20, 20, 83, 83, ButtonPlay[0x1AE9]);

Why do you want to pass the value of the item 1 place beyond your array?

I think you want to pass the pointer to your array

drawBitmap(20, 20, 83, 83, ButtonPlay);

PS drop the macros (define's), in C++ we have the saver alternative of const byte for pin definitions :wink:

Thanks for the help. I changed the code but its still not compiling. Any suggestions?

Thanks

Any suggestions?

Yes. Look at your definition for ButtonPlay. See that extern keyword? That means that the variable will actually be defined in another file. What other file have you defined it in, and how is this file supposed to know that?

Thanks Paul.

The folder consists of 2 files: the .ino & a folder called 'bitmaps'. Inside 'bitmaps is the .c file for the 'buttonPlay'

How can I include the .c file into my code?

Thanks

Thanks Paul.

Ive relocated the .c file in the same folder as the .ino file.

Thanks for the help
