fix unused variable error #161

Closed charcodelimit closed 1 year ago

charcodelimit commented 1 year ago

the variable font in glcdfont.c is never used in the file compiling with M5Stack Arduino Version 2.0.5 or newer signals the following error when compiler warning level is set to "All": 'font' defined but not used [-Werror=unused-const-variable=]
renamed the file to .h to make it clear to the compiler that it is a header file that will be included

The "Compiler warnings" setting in the IDE's preferences has to be set to "All". Thanks for asking, I have updated the commit comment to make this more clear.
