spi Miso problem

[Nero]

Hello,

I am using nRF SDK 12.2.0 , with nRF52832 on pca10040 hardware, and working with the example in examples/peripheral/spi/main.c to develop a driver for LIS2DE12. When I write a hexadecimal value I find a problem. I checked with the scope that CS, MOSI and SCK are correct, but I get 0xFF on MISO line .

Any ideas what to check?

Fro your screenshot it seems like you are writing 0x8F, but the datasheet of the LIS2DE12 device say that the WHO_AM_I register is located in address 0x0F. Are you sure you are sending the correct command? Please post code snippets showing what you are doing.
