This is the ReadMe file to the DF10CH Atmolight Controller Project.

Written by: Andreas Auras (yak54@gmx.net)

See the file COPYING for license information.

This project is hosted at:
http://projects.vdr-developer.org/projects/show/atmolight-controller

More documentation (currently only in german language) about this project can be found at:
http://www.vdr-wiki.de/wiki/index.php/VDR_Wiki:DF10CH_Atmolight_Kontroller


This project uses Objective Development's firmware-only USB driver V-USB
for Atmel AVR microcontrollers. For more information please visit
http://www.obdev.at/vusb/


This directory contains the firmware, DF10CH setup program and KiCad files of hardware design:

setup.py              Python script used for installation of Df10CH setup program
MANIFEST.in           File used by Python installation script


----------------------
Building the hardware:
----------------------

You will find design files of circuit and board layout for use in KiCad within the kicad/ subdirectory.
The files are generated with KiCad version 20090216-final.
File "10ch_pwm_ctrl-Lötseite.ps" is a postscript plot of the board layout
File "10ch_pwm_ctrl.lst" is a list of the needed hardware components for the board

You can produce other plot formats (e.g. Gerber, HPGL) and drill files by using KiCads plot features.
You can download KiCad from here: http://kicad.sourceforge.net
 

----------------------
Building the firmware:
----------------------

For building the firmware for the two Atmel AVR microcontrollers you need AVR-GCC installed.
On debian based systems these are packages avr-gcc, binutils-avr, avr-libc, avrdude

Each firmware sub directory contains a Makefile for compiling and flashing of firmware:

Compiling firmware:

	make
	
Flashing firmware with avrdude:

	make prog 	--> programming of flash, fuse and lockbits
	make flash	--> only programming of flash
	
Options to avrdude can be specified with:

	make prog AVRDUDE="avrdude -c stk500v2 -P avrdoper"
	

Normally only the bootloaders are flash into the processors. For this you need a dedicated AVR programmer.
The application firmware could later be flash via the DF10CH setup program.
This has the advantage that updates of the application firmware could be easily done over the USB
interface without the need for a dedicated AVR programmer.
If you like you could directly flash the application firmware without the bootloaders. But you will
lose the firmware update feature of the DF10CH setup program.


------------------------------------
Installation of DF10Ch setup program
------------------------------------

For running the DF10CH setup program you need a installed python environment version 2.6,
the python modules TKinter and PyUSB and a installed libusb library.
On debian based systems these are packages: python2.6, python-tk, python-usb, libusb-1.0-0

You can start the program directly from this distribution directory with:

	python df10ch_setup.py
	
You can also install the program to the default python installation location with:

	python setup.py install

Now df10ch_setup.py should be simply in your standard PATH for execution. Start it with:

	df10ch_setup.py


The setup program understands the following command line option:

	-d N		Set debug level to N
	-s N		Set number of simulated controllers. With this option you can play with
	     		the program without having hardware.
