Porting a module from Arduino {#porting}
=============================
Porting arduino libraries to libmaa as UPM libraries is usually fairly easy.
Porting arduino libraries to libmraa as UPM libraries is usually fairly easy.
The issues typically come from misunderstanding of how a non real time OS deals
with interupts and timers. It also highly depends on the sensor. A concrete
example is explained in detail on @ref max31855

The easiest way to do this is to have a look at a similar sensor to yours.
Typically create a class for your sensor with a constructor that defines the
pins it is on. This constructor will create the maa_*_context structs that are
pins it is on. This constructor will create the mraa_*_context structs that are
required to talk to the board's IO. An I2c sensor will create a
maa_i2c_context, keep it as a private member and require a bus number and slave
mraa_i2c_context, keep it as a private member and require a bus number and slave
address in it's constructor.
Typically in sensors a simple object->read() function is prefered, depending on
your sensor/actuaotr this may or may not be easy or not even make sense. Most
UPM apis have a simple set of functions.
### Mapping arduino API to libmaa
### Mapping arduino API to libmraa
Your constructor is similar to the setup() function in arduino, you should
initialise your IO the way you want it. This means initialising contexts
(private members) and setting the correct modes for them.
See the maa API documentation for exact API.
See the mraa API documentation for exact API.
