nrf52dk MBED SPI problem

[Hk]

Hi,

I have a problem with nrf52dk SPI with the mbed compiler. In the mbed pin names file for nrf52dk the pins are p22,p23,p24,p25. I connect many spi sensors and not working.

This is how I configure the spi 

SPI spi(SPIS_PSELMOSI, SPIS_PSELMISO, SPIS_PSELSCK);

How to solve this problem?

Hi Hk,

A little more information would be helpful. What does not work? What happens? 

Have you connected to the correct pins? ++

 

I am not familiar with the "mbed compiler", I would suggest that you post mbed questions on their forum if you want to use that.

 

I would rather recommend that you use our SDK which already has a SPI master application example which you can use.

You can use SES IDE (free) for development. 

 

Anyway, when working with SPI I would highly recommend that you connect the signals to a logic analyser (ex. this) to actually see what is happening with the communication.
