Yes, you can use SPI interface to communicate with the Arduino CAN bus shield. As you say, nRF52850 will work as a SPI master if you are using it with the CAN bus shield. The spi_master_using_nrf_spi_mngr example can be used as reference.

As for the library, you have to rewrite it in C like I said in my previous answer.

Thanks! Is the nRF52840 PDK compatible with Arduino CAN bus shield at SPI interface? Do I need to modify nRF52840's SPI driver? To my understanding, if arduino CAN bus shiled is applied, nRF52850 will work as a SPI master.

If so, which example from SDK14.2.0 I can use as the reference code? is it nRF5_SDK_14.2.0_17b948a\examples\peripheral\spi_master_using_nrf_spi_mngr?

For CAN bus library, do I have to rewrite the Arduino CAN bus library in C? I am using SEGGER embedded studio IDE.

Hi,

The nRF52840 PDK kits are hardware compatible with the Arduino Uno Revision 3 standard, making it possible to use 3rd-party shields that are compatible to this standard. It is hardware compatible but your code have to be in C. The Arduino CAN bus library is written in C++.
