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.

Hi Sara,

You should be able to use two TWI instances and a SPI instance at the same time, according to the memory instance table in the nRF52832 Product Specification, found here.

0x40003000 TWIM TWIM0 Two-wire interface master 0
0x40004000 TWIM TWIM1 Two-wire interface master 1
0x40023000 SPIM SPIM2 SPI master 2.
