ToyKeeper's flashlight firmware repository
==========================================
This is a collection of firmware for flashlights or torches, mostly
collected from BLF (http://budgetlightforum.com/). It's collected
here mostly for convenience, and to provide bug tracking and revision
control services for the code.
See the INDEX file to find out which projects might be relevant to
your needs.
Getting Started
===============
A general overview of what you need to get going is here:
http://flashlightwiki.com/AVR_Drivers
Some useful hardware for flashing firmware:
http://www.fasttech.com/product/1002900-atmega-attiny-51-avr-isp-usbasp-usb-programmer
http://www.fasttech.com/product/1011800-40-pin-splittable-ribbon-cable-20cm
http://www.digikey.com/product-detail/en/5250/501-1311-ND/745102
To set up an attiny dev environment on Ubuntu (13.10):
sudo apt-get install flex byacc bison gcc libusb-dev libc6-dev
sudo apt-get install gcc-avr avr-libc binutils-avr
sudo apt-get install avrdude avrdude-doc
Installing attiny dev tools on UNIX systems in general:
http://www.ladyada.net/learn/avr/setup-unix.html
To build a .hex file from a .c file, in Windows:
http://budgetlightforum.com/node/29081
After wiring everything up, this tests the connection to the ATTINY13A chip:
avrdude -p t13 -c usbasp -n
(you may need to put 'sudo' in front, on UNIX systems...
or set the suid bit on the avrdude binary, which is convenient but a
potential security risk)
To test if you can flash firmware correctly, or to restore a light to something
like a default state, try flashing the NLITE driver from DrJones. It's similar
to the default nanjg / qlite firmware, but better.
./bin/flash.sh DrJones/NLITE/nlite.hex
For a quick test to make sure your tool chain works and your flashing tools
are working, try the 'hello world' program:
cd hello_world
make
make flash
If that works, you should be ready to start making changes to the code, or
flashing any of the pre-built firmwares.
