History

Fredrik Osterlind b5c94910ac Renamed Java packages to match our contiki-os.org domain. Note that this commit does not affect external dependencies like /tools/mspsim. This is a very simple modification that affects a very large number of files in Contiki: Cooja, /platform/cooja, Collect-view, Coffe-manager, and Cooja simulation files (.csc). I've gone through Contiki to update all references I could find. Nevertheless, this commit will likely break external dependencies, like saved Cooja simulation files.		2013-11-20 16:43:27 +01:00

Hello-world

This adds the hello-world process in hello-world.c to the platform build, which prints "Hello-world" to stdout on startup.

The entire platform is built, with uip stack, radio drivers, routing, etc. So it is not usually a simple build! The native platform is the default:

make
./hello-world.native
Starting Contiki
Hello, world

When switching between ipv4 and ipv6 builds on a platform,

make TARGET=<platform> clean

else the library for that platform will contain duplicate or unresolved modules.

For example, using a loopback interface with the minimal-net platform:

cd /examples/hello-world
make TARGET=minimal-net
./hello-world.minimal-net
Hello, world
IP Address:  10.1.1.1
Subnet Mask: 255.0.0.0
Def. Router: 10.1.1.100
^C

make TARGET=minimal-net clean
make UIP_CONF_IPV6=1 TARGET=minimal-net
./hello-world.minimal-net
Hello, world
IPV6 Address: [aaaa::206:98ff:fe00:232]
IPV6 Address: [fe80::206:98ff:fe00:232]
^C

Note to AVR Raven users: Output goes to UART1, not the LCD. To see it,

make TARGET=avr-raven hello-world.elf

Load the .elf in AVR Studio and connect a hapsim terminal to the 1284p simulation.
