Trying to display a counter to TFT display (Solved)

.

Without looking at the library, I suspect that the text() method expects a string. const char* is a pointer to the first element of the string (and the last element is the null character.)

Is there another method in the library which can print a single character? This will let you display a count 0-9

Look into using the sprintf() function to 'print' the counter into a string in memory, which you can then use with the text() method.
