EMBEDDED QR CODE GENERATOR
Copyright 2010, tz@execpc.com.
Relased under ther terms of the GNU General Public License v3.
Targetd toward limited RAM systems - it tends to use more code and is slower but fits within an Arduino.
For linux/posix, type make. For arduino, type make -f Makefile.avr.
qrenc defaults to version 6, level L ecc, but you can specify the version, or the version and the error level.
dofbits will generate a C file with the frame for one version/ecc level which will save a lot of RAM. This file will link with qrencode.c
