Using Two TWI and One SPI

[sara]

My project needs to use 2 different TWI instances and 1 SPI instance. I knew that it is not possible to use three instances at the same time in nRF52.

To implement 2 TWI and 1 SPI, can I use 1 TWI SW and 2 TWI HW together? (I found TWI SW driver is in the "deprecated" folder.) Or, is there any other solution to do it?

P.S. My environment -> nRF52832, SDK12.2, s132

Thanks.

You can have multiple devices on one TWI bus, given them different addresses. You should never (well rarely) actually need two separate TWI peripheral instances, TWI is designed to talk to multiple slaves. That's the easist way to do it.
