SPI for AoA output

[Marques]

Hello, 

I would like to know how can i use SPI on the radio example. 

I'm using (programming) the radio example, receiver, for AoA and it's working so far. What i'm trying to do now is to print those angles with SPI to PC, via SPI-ethernet PoE, I've imported the libraries needed and copy the sdk_configurations from the SPI example. I've deleted everything from the "apply_old_config" but i'm still having some errors like "'NRFX_UARTE0_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_UARTE_INSTANCE'?" (I'm using SEGGER), most part of the errors are from uart or uart instances.

Is this because of nrf52811 memory or am I missing some file/configuration?

Thank you so much for your attention!

Best regards,

Catarina Marques

Hi Catarina, 

Try to define the following definitions in sdk_config.h:

#define UART_ENABLED 1
#define UART0_ENABLED 1
#define NRFX_UARTE_ENABLED 1
#define NRFX_UART_ENABLED 1

See the similar post.

Good morning

Thank you so much for the fast reply! I've defined those uart as asked and now i'm having an SPI instance error:

#error "No enabled SPI instances. Check <nrfx_config.h>." 

I've  tryed the example, doing the same defines to the uart and this error is still appearing.

For SPI should I follow this guide too?

Thank you so much for your attention.

Best regards!

I've define SPI and SPIM as 0 on sdk_config.h and the error changes to:

"NRF_DRV_SPI_INSTANCE_O" undeclared here (not in a function); did you mean "NRF_DRV_SPI_INSTANCE_"?

at line 120 from nrf_drv_spi.h:

"#define NRF_DRV_SPI_INSTANCE_(id)   NRF_DRV_SPI_INSTANCE_ ## id "

Hi, 

Enable SPI0 INSTANCE in the sdk_config.h. See the similiar case.

Yes! It's working, thank you!

In my case I had to remove the file nrfx_spim.c from the drivers, otherwise I was getting errors about SPIM instance.

Thank you so much for your help and attention!
