Adafruit STEMMA Soil Sensor doesn't change capacitive value

Dear Adafruit support team,

I am currenty working on a school project for my engeneering class.
There we use the Adafruit STEMMA soil sensor and a Adafruit LED 7segment clock.

Becaus we have to work with a Nucleo F446RE I ran into
some problems with the soil sensor and the LED clock.

1) STEMMA SOIL SENSOR:
I couln't use the Arduino example in Mbed, so I tried to modify the example.
But this wasnt a success.
When I compiled it with the Arduino programmenviroment the Sensor could only read the temperatur.
For the moisture sensor I got a non changing value of 59395.
It was the same when I conected the sensor with an Arduino.

Is there a known problem concerning the moisture data in the example programm.

Becaus I coulnt run it properly with my Nucleo Board I wanted to write the i2c code myself.
Do you konw which adress I have to use, I couldnt find it in the seesaw datasheet?

2) 7 Segment LED:
Due to the problem with Mbed I coulnt run the 7segment LED Backpack on the Nucleo Board,
I want to write the code myself. (It didnt even work with the Arduino Programm.)

Do you konw the i2c adress I need to use?


Thank you for your support. I realy appreciate your prodacts.

Best wishes,
Denise
