nRF52832 SPI interface with 3 SPI slaves advice

Hi Haakonsh

In nRF52832 Datasheet, the base address of UART 0 is 0x40002000 and the base address of SPI0/TWI0 is 0x40003000.

It is different base address of these I/F instance 0.

I think it can be used UART0 and SPI0 or TWI0 together.

Please kindly check again.

Thanks.

Hi Haakonsh, thanks. Didn't realise SPI0 shared resources, but not using those two modules so should be ok.

You can use 3 SPI interfaces, but the limitation is that these instances are shared with the UART and TWI peripherals. This means that if you use SPI0 you cannot use UART0 nor TWI0, etc.
