readInternalTemperature(); - why isn't this part of the ArduinoCord-samd ?

Hello All,

I've seen the thread regarding the LSM6DS3 (arduino.cc forum) and downloaded that and am using it - but I also am using the ElectronicCats_InternalTemperatureZero lib as well and there's less than a 1 degree C of difference - I've used a temp gun to verify and they are both very close - so I'm wondering why this has not been added to the SAMD core as in previous cores where I see readInternalTemperature(); ???

For the ATSAMD21G18 https://www.microchip.com/wwwproducts/en/ATsamd21g18 the internal temp sensor is certainly available:

mentioned in the above in the Voltage Reference System (VREF).

I also see a pull request here:
https://github.com/arduino/ArduinoCore-samd/pull/277/files

And have to wonder why that wasn't implemented.

Regards,
John W.

Start by reviewing the referenced ArduinoCore-samd pull request #277, the ElectronicCats_InternalTemperatureZero library, and the ATSAMD21G18 datasheet section on the internal temperature sensor. Determine whether the core should expose readInternalTemperature(); and what validation is required; done means a resolved decision and, if accepted, the API and supporting tests are covered.
