# ----------------------------------------------------------------
# Generic makefile for the Padauk open source toolchain
# 
# Usage:
#
# make					- build project
# make flash			- flash binary to microcontroller
# make start			- start program on microcontroller	
# make clean			- clean
# make compileandrun	- compile, flash and start
#
# Requires the SDCC compiler and the easypdkprog programmer
