Examples and demos
|
||
|
==================
|
||
|
|
||
|
There are several basic examples provided with the library.
|
||
|
|
||
|
Parse block of data
|
||
|
^^^^^^^^^^^^^^^^^^^
|
||
|
|
||
|
In this example, block of data is prepared as big string array and sent to processing function in single shot.
|
||
|
Application can then check if GPS signal has been detected as valid and use other data accordingly.
|
||
|
|
||
|
.. literalinclude:: ../../examples/example.c
|
||
|
:language: c
|
||
|
:linenos:
|
||
|
:caption: Minimum example code
|
||
|
|
||
|
Parse received data from interrupt/DMA
|
||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
||
|
Second example is a typical use case with interrupts on embedded systems.
|
||
|
For each received character, application uses ``ringbuff`` as intermediate buffer.
|
||
|
Data are later processed outside interrupt context.
|
||
|
|
||
|
.. note::
|
||
|
For the sake of this example, application *implements* interrupts as function call in *while loop*.
|
||
|
|
||
|
.. literalinclude:: ../../examples/example_buff.c
|
||
|
:language: c
|
||
|
:linenos:
|

|

||
|
|
||
|
Distance and bearing
|
||
|
^^^^^^^^^^^^^^^^^^^^
|
||
|
|
||
|
Library provides calculation of distance and bearing between ``2`` coordinates on earth.
|
||
|
This is useful if used with autonomnous devices to understand in which direction
|
||
|
device has to move to reach end point while knowing start coordinate.
|
||
|

||
|
