This repository provides example code for the development modules made by
Techno-Innov.

It has support for the LPC1224 as used on the development modules, and
for the peripherals found on the development modules (user led, eeprom,
temperature sensor, CC1101 RF transceiver, ...).
Support for various other cool stuff is added when we play with it.

Example applications are created in the apps/[module name] directories for
each module, with one sub-directory for each application. These are (and must
stay) independent.
Each module has it's own directory under apps/.

More usefull stuff is up to you. Creating an app is *very* simple. Copy
an example from apps/[module name]/ to the name you want and start coding.
** Please, no spaces (or special characters) in the directory names ! **

BUID and FLASH

Build has been tested using gcc, and only gcc, in the version provided by
Debian GNU/Linux distribution, and a few other binary versions available for
download on the Internet, but any ARM gcc toolchain should do.

In order to get the debian ARM gcc cross-toolchain you should install the
following packaages : gcc-arm-none-eabi, binutils-arm-none-eabi

There's no need for the related libc package here, the libc does not fit
in our micro-controller memory. Instead have a look at the content of the
lib/ directory, and add stuff there.

Once done you should build using the provided makefile by running the
simple "make" command in the base directory, which will build all apps, or
run "make <module_name>/<app_name>" to build a specific application. You can
also run the simple "make" command in the specific app subdirectory to compile
this application alone.

To flash the binary (the one with .bin) to the LPC Flash you will need the
lpctool package, now packaged for Debian, starting with Jessie, or available
in our git repository : http://git.techno-innov.fr/lpctools (Clone using :
git clone http://gitclone.techno-innov.fr/lpctools and then build (make) and
use :)
Usual command lines :
   lpcprog -d /dev/ttyUSB0 -c id
   lpcprog -d /dev/ttyUSB0 -c flash app_name.bin
See lpctools readme and lpcprog or isp help (-h) or manpages for more
information.
