Basic SPI reads and writes

[RodWatt]

Hi,

I have a SPI peripheral connected to the nRF960 DK. In order to access this correctly, I need to be able to write a byte to a specific address first and then read back from specific addresses. 

I can run the basic SPI example

https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/spi

which carries out a basic loop back. This all works fine but I can't see how to write a specific byte to a specific address or read a specific address.

So, ideally I would like to write 0xD2 to address 0x80, wait 1 second and then read data from address 0x00.

Can you point me to a simple example please?

Ta,
Rod

Hello Rod, 

The SPI example you are using is the only one we have at the moment. The example is using the built-in SPI functions of the Zephyr project, perhaps you are able to find what you are looking for in the Zephyr samples? Also, have a look at the Zephyr SPI API and the SPI header file.

Ref. similar answer given by my colleague Jan Tore here. 

Kind regards,
Øyvind

Hi Øyvind,

I went back to the reply from Jan Tore on the ticket here. I realised that the BME280 has both an I2C and an SPI interface. So, I thought if I can get this sensor working over SPI and I can then try and migrate it to my own SPI sensor.

I have successfully connected and ran the BME280 sensor over I2C. I am now trying to access this over SPI. 

Im using the sample given here, 

https://github.com/zephyrproject-rtos/zephyr/blob/master/samples/sensor/bme280/src/main.c

I have set up SPI in my overlay file as suggested by Jan in the other ticket.

};

and also I have enabled SPI in my conf file

# SPI
CONFIG_SPI=y
CONFIG_SPI_3=y
CONFIG_SPI_3_NRF_SPIM=y
CONFIG_BME280=y

However, I get an error

Any thoughts?

Hello Rod, 

My apologies for the late reply, your question went under my radar for some reason.

Can you tell me what version of the nRF Connect SDK you are running? 

In your prj.conf file, if not there, can you please add:

CONFIG_MAIN_STACK_SIZE=4096

Kind regards,
Øyvind

[RodWatt]

Hi Øyvind,

No problem. 

I have version 2.6.2 installed but am not using it directly. I use cmake and ninja for building code and programming.

I have this entry in my pro.conf file, here is the full file

CONFIG_CONSOLE_SUBSYS=y
CONFIG_CONSOLE_GETCHAR=y
CONFIG_GPIO=y
CONFIG_STDOUT_CONSOLE=y

CONFIG_SERIAL=y
CONFIG_STDOUT_CONSOLE=y
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_TEST_RANDOM_GENERATOR=y

CONFIG_I2C=y
CONFIG_SENSOR=y

CONFIG_NET_BUF_USER_DATA_SIZE=1

CONFIG_LOG=n
CONFIG_LOG_DEFAULT_LEVEL=4
CONFIG_HEAP_MEM_POOL_SIZE=1024

CONFIG_NEWLIB_LIBC=y

# SPI
CONFIG_SPI=y
CONFIG_SPI_3=y
CONFIG_SPI_3_NRF_SPIM=y
CONFIG_BME280=y
CONFIG_SPI_NRFX=y

 

Regards,

Rod

Hi Rod, 

Sorry, our naming convention can be a little confusing. nRF Connect (for desktop) 2.6.2 is not what I mean here, but it can be used to install NCS. nRF Connect SDK (NCS) is either (git tag) v0.3.0 or (git) master branch (0.3.99). Where the former is installed as described in the Getting Started guide and the latter is usually installed using west (but does not work in SES).

Can you please try to remove either the i2c or spi config from the overlay with corresponding CONFIG from prj.conf? This to see if there is anything wrong with the configuration

[Øyvind]

Can you also run "git log" in your nrf folder, so see what the last commit was?

[RodWatt]

I should have the latest and greatest, after installing I did run west update. How can I check the version?
