I'm attempting to utilize an open-source project called UTFT-Energia.
Unfortunately, when I attempt to test out the code, I receive the following errors:
/UTFT_Bitmap_Launchpad.cpp:34: undefined reference to `UTFT::InitLCD(unsigned char)'
/UTFT_Bitmap_Launchpad.cpp:36: undefined reference to `SmallFont'
/UTFT_Bitmap_Launchpad.cpp:36: undefined reference to `UTFT::setFont(unsigned char*)'
The UTFT class is defined in the header file.
Any help getting this annoying error message to disappear would be appreciated. Thanks in advance!
The header file is UTFT.h:
