PID control
Show the struct PID_DATA and pidData_t definitions.  Sometimes there are signed, unsigned, or overflow problems simply because the wrong data types are used.

I2C intermittently working on SAML21J18B (SAML21 XPLAINED PRO)
Did you put the oscilloscope on the SDA and SCL lines?  Setup triggering for positive or negative pulses less than 1.25us (less than the 1/2 wave clock speed for your...

I2C intermittently working on SAML21J18B (SAML21 XPLAINED PRO)
