On this page you will learn how to create your first Lua script for your Armadeus board.

Installation

Lua interpreter is not installed in the default rootfs. Lua version installed by Buildroot is x.x.

• Launch Buildroot's menuconfig:

armadeus$ make menuconfig

• In

choose

• choosing Lua package automatically selects readline and ncurses one
• then save your configuration and build your system:

armadeus$ make

• copy generated rootfs to your NFS directory or on your MMC/SD. If you already have an existing rootfs then just make a:

armadeus$ cp -r buildroot/build_arm/root/usr/ /local/export/

Here /local/export/ is my NFS directory.

Source code

First take your favorite editor/IDE and create the following script:

print "Hello from APF9328 ! Today it's:"
print(os.date())

Save it as example.lua

Compilation

Not needed. Transforming Lua scripts in "executables" with Luac hasn't been tested yet.

Running

• Copiez votre script example.luaà votre carte APF9328 via votre répertoire d'export NFS ou sur votre MMC/SD
• ensuite sur votre console APF, lancez-le:

# lua example.lua
Hello from APF9328 ! Today it's:
Thu Jun  6 21:57:17 2007

Maintenant, vous y êtes ! ;-)
