Normally I used the ATmega256rfr2 Chip, recently I bought the SAMR21 Xplained Pro to test out the chip.
I could nearly user every function I normally need, like generate network, ADC, UART and so on.
But the I2C seems to crash, when using the predefined BitCloud functions.
Did anyone else have this problem and has a solution?
As soon as I am trying to read or write something with the I2C Descriptor the board crashes and has to be reset.
Any suggestions or remarks?
