This directory contains a number of test applications contained in their own sub-directories. Within each sub-directory are two makefiles; one called Makefile and the other called Makefile.test. By default when make is run it will read Makefile. make --- builds the application for the ATmega8 make program --- programs the application into the ATmega8 flash memory make clean --- deletes the object and executable files The other makefile, Makefile.test, will compile the application natively for the PC with a test scaffold replacing the AVR dependent modules. This allows the application to be run and debugged on a PC. make -f Makefile.test --- builds the application for the PC make -f Makefile.test clean --- deletes the object and executable files
