Can Z-UNO v2 use Adafruit libraries?
Hello I´m a non-professional programmer but I´m able to understand syntax/structure and do some coding. This weekend I spent connecting a z-uno v1 to the SCD30-sensor (T/RH/CO2), and I used a lot of time. I see that there are a lot of Adafruit libraries that supports sensor that I´d like to use, but...

Re: Convert from hex to float
I can probably also do with the two most significant bytes:
0x440B

Using an online hex->float calculator I see that this hex-value correspond to: 557.606 But how do I get there in the z-uno? I ...

Re: Adafruit with I2C on Z-uno
I gave up trying to the Adafruit library and implemented some code using the wire.h library. Case kind of closed!

Adafruit with I2C on Z-uno
Hi I´m want to connect the CO2/RH/T-sensor Sensirion SCD30 to my Z-uno. To do this I´d like to use some of the already exixting libraries: Adafruit_SCD30.h However, it seems like this library expects a dedicated I2C interface on the board while the Z-uno has a software I2C only, that is taken care o...
