 into a generic TM1637 PIC library. The library functions are in file TM1637PIC.c
 and there is also a .h file to include in the application code.

+See the libdemo application for how to use the library. Note the need to call the

 The library is intended to be resource sparing for use on 8 bit PICs. It does not
 attempt floating point handling or offer full printf() style output capability.
