<td colspan=2><tt>The PiXtendV2 base class can be used to build PiXtend V2 modules, which use the same code base, thus reducing<br>
code multiplication. This class implements the most basic functions, properties and infrastructure needed to<br>
create a PiXtend V2 module in Python. This class cannot run on its own, it needs to be inherited by a child<br>
class and the functions '_pack_spi_data' and '_unpack_spi_data' have to be implemented there as these are<br>
defined as abstract functions and cannot be used directly.<br>
Furthermore, for the SPI data transfer to work correctly, the child class needs to implement a list[int] variable<br>
which holds the data which is sent to the microcontroller. The needed list[int] length can be found in the<br>
SPI protocol specification of the PiXtend V2 board.<br> </tt></td></tr>
