TWI Slave To Master Dynamically

[alx]

Hi, I'm working with the nRF52840-DK and need to be able to receive (slave) and generate (master) data on the same I2C lines. I'm aware this target doesn't support multi-master mode.

Independently, implementing the master or slave modes is relatively simple following the examples but I was wondering if it is possible to switch between instances dynamically? Or is there any other way to achieve this?

Thanks,

A.

Hi,

Yes, that is possible. Remember to enable PERIPHERAL_RESOURCE_SHARING_ENABLED in sdk_config.h, and properly uninitialize the first instance, before initializing the other one.

Awesome, thanks! It worked.
