Is there any example on interfacing nrf52840 with icm 20601 using spim?

Hi guys, I just want to know if there's a way for the above and how if yes.

Hi Jerry,

That could be a problem with SPI PHASE and POLARITY. 

Kindly check all the 4 cases with those.

Warm Regards,

Kumar

Hi,Kumar

I had think about that and I've tried to check all the 4 cases. But, strangely, the device ID returned was always 0x00 in the 4 cases.....

nrf_drv_spi_transfer() returned NRF_SUCCESS, seemed that there's no problem in transmission.  But the returned value 0x00 showed that read_data function wasn't work.......

Have you read and write icm successfully by spi?Can you show me your code for a example?

thanks a lot.

Hi Jerry, 

Should there be a command delay between the write, read functions?

Or try a different function for reading from SPI DRIVER instead of spi_transfer one. HAL_SPI DRIVER functions are better if we have.

Also, make sure that MISO and MOSI are properly connected, just in case.

No, I couldn't work on that sensor as I moved to a ST one
