Hi picatostas,

I'm using the default example ble_app_uart and add the driver spim3.

Therefore, the peripherals used are Timer0 RTC0 UART0 GPIOTE SPIM3

I confirm that TWI0-3 and SPI0-3 are not used

I tested SPIM0-3, SPIM0-2 test OK,butt SPIM3 test failed

Why did I debug the SPIM3 register with 0?

It looks like an initialization problem.

Where should I change to use SPIM3?

Thank you for all your assistance.
Kind regards,
Peter.Min

Hi Peter,

What other peripherals are you using ? TWI and SPI usually share resources handlers and you have to be careful with that
