Subject: Tidied up and reduced the verbosity of the makefile.
X-Git-Url: http://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=d5cbb2c06a5deef0540a3a4cd72d9a667db305fb;p=avr%2Ftimer-demo.git

Tidied up and reduced the verbosity of the makefile.

Note: on windows installed MinGW to get mingw32-make but the avr-gcc
compiler tools are provided from the Arduino IDE installation.
