It seems that the default configuration for the example_algo.sln is to use SPI4 to communicate between the SAMG55 and the sensor chip (IIM_42652).
I wanted to evaluate the I2C mode of operation and changed in main.c
/*
* Select communication link between SmartMotion and IXM42xxx
*/
//#define SERIF_TYPE IXM42XXX_UI_SPI4
#define SERIF_TYPE IXM42XXX_UI_I2C
After making this change and rebuilding,running the code I see the I2C master trying to communicate with a slave at address 0x68 but always gets NAK'ed.
Has anyone had success using the I2C mode of communications with either the EV_IIM-42652 or the DK-42652? Any tips welcome!
Thanks
Jim
