Inlcude SPI and ADC to pheripheral_hr example with NFR5340DK

[Epasta]

Hello,

I am using "pheripheral heartrate" example on SES, but I can not integrate SPI or ADC.
How can I add "nrf_spi.h" and "nrf_adc.h" and relative C files on that project?

If I use "nrf_pwm.h" or "nrf_gpio" it works perfectly.

Can you help me?
Thanks

If you look at the peripherals of the nRF5340, you can see that it does not have an SPI or ADC, however it does have the peripherals SPIM, SPIS and SAADC. Try including nrf_saadc.h and nrf_spim.h instead:

#include <hal/nrf_spim.h>
#include <hal/nrf_saadc.h>

Is there a reason you're using the low level HAL? You may save some work by using some higher level APIs like the nrfx or the Zephyr API.

Hy Simon,

thank you for yuor answer.
No there are not particular reason for using the low level HAL.

For the higher level i have to include the following?
#include <drivers/spi.h>
#include <drivers/adc.h>.

Thanks again for you time.
Best regards

Yes, you are correct. In addition you have to set CONFIG_SPI=y and CONFIG_ADC=y in the prj.conf, and for the SPI you need to configure the hardware in an overlay file as well. In this answer I have provided some samples that demonstrates how to use SPI in NCS/Zephyr.

Take a look at the NCS tutorial part 3, section 3.5 Add the ADC peripheral, which demonstrates how to use ADC. It may be useful to complete 3.2 Set it up, 3.3 Build and flash it and 3.4 Modify the device tree first (also part 0 + part 1 if you got time).

Best regards,

Simon
