Build
|
|
|
|
|
=====
|
|
|
|
|
|
|
|
|
|
Supported build platforms are Linux, FreeBSD and Windows (via Cygwin). Due to
|
|
|
|
|
customized linker scripts, simulator support is currently limited to x86 and
|
|
|
|
|
x86_64 archs. Following dependencies have to be met:
|
|
|
|
|
|
|
|
|
|
Linux / FreeBSD
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
Package names are based on Debian/Ubuntu repositories. Please adapt the names
|
|
|
|
|
according to your Linux distribution (or FreeBSD for that matter).
|
|
|
|
|
|
|
|
|
|
* build-essential (pulls in an ordinary gcc build tool chain for the host)
|
|
|
|
|
* make (gmake on FreeBSD)
|
|
|
|
|
* libncurses5-dev
|
|
|
|
|
* gcc-avr
|
|
|
|
|
* avr-libc
|
|
|
|
|
* binutils-avr
|
|
|
|
|
* avrdude
|
|
|
|
|
* freeglut3-dev
|
|
|
|
|
|
|
|
|
|
Windows
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
* [WinAVR](http://winavr.sourceforge.net) (includes avr-gcc and avrdude)
|
|
|
|
|
* [Cygwin(64)](http://www.cygwin.com/)
|
|
|
|
|
* make
|
|
|
|
|
* gcc-core
|
|
|
|
|
* libncurses-devel (Cygwin)
|
|
|
|
|
* libncursesw-devel (Cygwin64)
|
|
|
|
|
* [libusb-win32](http://sourceforge.net/apps/trac/libusb-win32/wiki) if you want
|
|
|
|
|
to use your USBasp programmer device with avrdude on Windows
|
|
|
|
|
|
|
|
|
|
Configure
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
Open a (Cygwin) terminal, change to your checkout directory and type:
|
|
|
|
|
> make menuconfig
|
|
|
|
|
|
|
|
|
|
This starts a curses based text interface for configuring certain aspects of
|
|
|
|
|
your target platform. Be careful if you use an IDE like Eclipse to manage the
|
|
|
|
|
build, as integrated terminal emulators tend to choke on curses generated shell
|
|
|
|
|
output. Make sure that 'make menuconfig' has been run at least once in an
|
|
|
|
|
ordinary terminal emulator after a fresh checkout or after issuing 'make
|
|
|
|
|
mrproper'.
|
|
|
|
|
|
|
|
|
|
Compile
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
To build for the actual target platform, just type:
|
|
|
|
|
> make
|
|
|
|
|
|
|
|
|
|
If you want to test and debug your code within a GUI application, you can use
|
|
|
|
|
the simulator:
|
|
|
|
|
> make simulator
|
|
|
|
|
|
|
|
|
|
In case you build on FreeBSD, just use 'gmake' instead of 'make'.
|
|
|
|
|
|
|
|
|
|
You can start the simulator by typing ./borgsim(.exe)
|
|
|
|
|
|
|
|
|
|
Simulator Handling
|
|
|
|
|
------------------
|
|
|
|
|
|
|
|
|
|
Please keep in mind that the simulator is NOT an emulator. All it does is
|
|
|
|
|
compile the source to a native host application so you can step through your
|
|
|
|
|
C-Code. The GUI thread reads the simulated frame buffer every 40ms and draws its
|
|
|
|
|
contents.
|
|
|
|
|
|
|
|
|
|
Joystick directions are simulated by the WASD keys and SPACE acts as the fire
|
|
|
|
|
button. The OpenGL based simulator (Linux/FreeBSD) enables you to adjust the
|
|
|
|
|
viewing angle of the LED matrix via the arrow keys (not available on Windows).
