Arduino compatibility example
|
||||
=============================
|
||||
|
||||
This example shows that it is now possible to re-use arduino sketches in
|
||||
Contiki. This example documents the necessary magic. Arduino specifies
|
||||
two routines, `setup` and `loop`. Before `setup` is called, the
|
||||
framework initializes hardware. In original Arduino, all this is done in
|
||||
a `main` function (in C). For contiki we define a process that does the
|
||||
same.
|
||||
|
||||
See the documentation file in apps/contiki-compat/README.md
