<![CDATA[Watering unit never stop]]>I plugged the watering unit in a Core Gray (3 buttons)
The pump starts but never stop:

  • I tried with the Watering Test
  • I tried with the example of the documentation and set the pump status to 0
    It's impossible to stop the pump!
    What did I miss?
    Do I need a Core 2? But nothing is written about this

in the M5Stack world there are 3 different Groove ports (A - red, B - black and C - blue) for different types of units.

PORT                 PIN         Note:
PORT-A(Red)    G21/22  I2C
PORT-B(Black) G26/36  DAC/ADC
PORT-C(Blue)   G16/17  UART

The Groove port built into M5Stack (Gray, Fire, Basic, etc.) is port A (red).

However the watering unit needs to be connected to port B (black) for the example to work.

Note: Groove port B (black) and port C (blue) are available on the M5GO Bottom.

Thanks
Felix
