\par Usage
- Link the \c pbdrv-mod library with your main executable
-- Load an \ref pb_ext "extension"
\note This driver is automatically enabled if the variable \c ARDUINO is
defined in your CMakeLists.txt (it is by default when using
Arduino-CMake-Toolchain).
+\note This driver automatically includes the \ref pb_ext_freertos
+"FreeRTOS extension" for deferring calls to \c pb_i2c_recv() from the I2C ISR.

A complete example for this driver is available in the \ref puzzle/dummy
folder.
