The "setup" parameter in the {{fname|1=DinControler.setup( self, setup=None, loop=None, on_tasks_create=None )}}
The {{fname|setup}} parameter in the {{fname|1=DinControler.setup( self, setup=None, loop=None, on_tasks_create=None )}} is used to define and initialise additional hardware/sensor/bus connected to myDin.
The parameter must be the reference to a regular function accepting a "din" object as parameter.
'''Good practice:''' instead of defining global variable, it is recommended to add a new attribute on the "din" object. By doing so, the ''userloop''' can easily access the new object.
The following [https://github.com/mchobby/micropython-mydin/blob/main/examples/din_controlers/pico3mod/async-qwiic-bme280.py async-qwiic-bme280.py example] show how to create such reference and how to retreive it in the ''userloop''. The sensor is a [https://shop.mchobby.be/fr/cartes-breakout/684-bme280-capteur-temperaturehumiditepression-i2cspi-stemmaqtqwiic-3232100006843-adafruit.html BME280 sensor wired] on the I2C bus.
<syntaxhighlight lang="python">
from mydin import configure
from mydin.pico import Pico3Mod
from mydin.backplane.relays import TwoRelay3Mod
import time, sys
from bme280 import *
din = configure( Pico3Mod, TwoRelay3Mod )
def setup( din ):
# Add a new attribute to "din" instance
din.sensor = BME280( i2c=din.i2c, address=BMP280_I2CADDR )
async def loop( din ):
# temperature (celcius), atmospheric_pressure (hPascal), Relative_humidity (percent)
temp, hpa, rh = din.sensor.raw_values
print( "temperature",temp, "pressure", hpa, "humidity", rh )
din.setup( setup=setup, loop=loop )
din.run()
</syntaxhighlight>
Notice the definition of the {{fname|def setup():}} function and its referencing in {{fname|din.setup( setup='''setup''', loop=loop )}} call.
