i am currently working on an extras module for reading Honeywell ABP-series pressure sensors. During testing I was using a spare ATmega328 as my mcu - but just tried moving the code to its destination machine which is run by a SAMD21 mcu.
Here I get a “i2c_read not supported on samd21” error and just realized that i2c reading indeed is not implemented in the microcontroller firmware for ATSAMD.
Can anyone tell why that is? Just not coded and tested yet, or are there issues that make this impossible?
I would be happy to add and test this if there are chances to get it working…
