#
# This Makefile assume a single "current project" named "project" Compiling
# and linking a project involves typing "make {project_name}".
#
# After this, use "make load" load to projct into a target ATtiny part via
# the programmer.  This Makefile is setup to use the PicoWeb PC parallel
# port programmer (see http://www.picoweb.net/download/).
#
# Each "project" is expected to have a ".h" file which begins with the
# name of the project and ends with ".h".  This C header file contains
# all the I/O definitions of that project, including the processor clock
# rate, the Vcc voltage of the part, the I/O pin definitions for things
# like the LEDs and serial ports.  The "make project_name" logic copies
# this I/O definition header file into a file named "_io.h".  This second
# file becomes the "current" project's I/O definition file.
#
# Notes: 
#
# (1) This Makefile depends upon a number of the WinAVR "Unix-like"
#     command-line programs like "rm", "cp", "diff", etc.
#
# (2) This logic only works with gcc version 2.95.2 19991024.
#
# (3) This Makefile assume the use of GNU make (a.k.a. avr-make).
#
# (4) The ATtiny serial programmer (avrtiny.exe) can uses the PC parallel
#     port. This program works under Windows9x, and under WindowsXP with
#     a special driver and I/O premissions "shim" program.  The auther
#     suggests that you use your own programmer.  This Makefile produces
#     Intel Hex output which should allow use with almost any AVR
#     programmer.
#
# (5) This Makefile uses an AVR programmer which automatically reads
#     the OSCCAL internal oscillator "calibration byte".  The "make load"
#     logic then puts this byte in the last location of program memory.
#     Most of the sample programs use this byte and the macro "osccal() to
#     read this byte value and "calibrate" the ATtiny internal oscillator.
#     If *your* programmer does not do this, or and do not define the macro
#     OSCCAL indicating where in program memory *you* have stored this
#     value, then your oscillator will likely be "mis-calibrated" to 0xff!!
#
# (6) You will probably want to set your Windows PATH as follows:
#
#         set PATH=c:\ATtiny\AVRSW\bin;%PATH%
#
#     before using this software
#
# (7) This Makefile will work under Linux if you happen to have a
#     gcc 2.95 release of avr-gcc (like I do!)
