Stopwatch using a 32 x 8 LED Matrix

I'm pretty sure that you did not activare verbose output

With verbose output activated you should get hundreds of lines in the output-window

did you copy the compiler-messages this way?

EDIT:
it might be that it depends on using "<" ">" not sure about that
#include < SmallDigits.h >
two suggestions:

try to use "

#include " SmallDigits.h "

put the file SmallDigits.h into the folder where the other

Parola_Fonts_data.h file is stored

a final way which is unconventient is to use the complete path
#include "C:\ .....all.the-way-down-to-were-the-SmallDigits.h is stored-path"
