SDK : S140 17.1.0

CHIP : nRF52833

I try to write and read data by SPIM0.

Wirte works find but when read data oscilloscope like this.

But, receive buffer data is like this.

temp_rx_buf[0] = 0x87 is correct value. 1000 0111

Not 0100 0011 1000 0000

Hi,

Is the SPIM0 configured using the same SPI mode (see Table 2 in Pin configuration), as supported by the SPI slave device you are interfacing?

What slave device are you interfacing?

Can you post your SPIM configuration and code for performing transactions?

Best regards,
Jørgen

Hi

I solved this problem to setting spim mode in spim configuration.
NRF_SPIM_MODE_0 to NRF_SPIM_MODE_1.
