How to read sensors with SPI

Hi, I used the SPI and SPIS examples to read a type K thermocouple with a max31856, the problem is that in no example do I get any response or data from the sensor, I wanted to know if someone tried to read thermocouples with the nRF52840DK or if they have any advice How to read sensors with SPI.

  • Your question is quite vague. You may receive a better response if you can provide more details of your setup including how you are configuring the SPI driver. 

    It sounds like the 52840 is the SPI master and thermocouple is the SPI slave device. Make sure you are using the SPI master drivers in your application (not SPIS)
