Dependencies
============
make
avr-libc
binutils-avr
gcc-avr
avrdude
dfu-programmer
libusb-dev (for teensy_loader_cli)
udev example rules
==================
DFU programmable Boards:
------------------------
(something like this is likley is already installed via the avrdude package)
SUBSYSTEM=="usb", ATTR{idVendor}=="03eb", ATTR{idProduct}=="*", TAG+="uaccess"
Teensy Boards:
--------------
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", TAG+="uaccess"
Arduino Boards:
---------------
SUBSYSTEMS=="usb", KERNEL=="ttyUSB*", ATTRS{serial}=="A6008hTA", SYMLINK+="arduino", TAG+="uaccess"
Replace "A6008hTA" with the serial of your arduino board. You can obtain it
with the following command:
udevadm info --name /dev/ttyUSB0 --attribute-walk | grep ATTRs{serial}
(replace ttyUSB0 with the actual device your arduino uses)
Build
=====
Getting the source via GIT:
---------------------------
git clone git://git.spreadspace.org/avr-utils.git
cd avr-utils
make -C contrib
build and flash blink example
-----------------------------
# cd blink
adapt Makefile (set BOARD_TYPE)
# make program
Some Hints
==========
The object files for builded libs will be called lib-<name>.o so make sure
not to use files named like this for your own code. i.e. if you want
to use the `led` library it's not possible to have a source file name
lib-led.c inside your project.
The anyio lib provides a failover between serial and usb-serial (using LUFA)
streams. It's not safe to use any STDIO functions inside interrupts.
To use LUFA in your project you have to provide the path to the LUFA
source code. You may do this by calling `make` inside the contrib tree.
But any external path is ok. In order to build the lufa object file the
build system has to call `make clean` inside the LUFA_PATH so make sure
there is no lufa build inside which you still need. Also paralell builds
of several projects using the same LUFA_PATH is not possible.
