Enable SPIM0 and TWIM1 Drivers in KConfig NCS

[adnankhalid]

Hello,

I am trying to enable the SPIM0 and TWIM1 drivers for my current project. Under the VS Code GUI for KConfig, I see the options, but they are grayed out and cannot be selected. Can someone guide me as to how to enable them? Maybe I have something enabled/disabled that is causing this. Manually adding them in the KConfig only produces compile errors. I am using nRF Connect SDK v2.1.2 and have the nRF52 DK (nRF52832) board for eval purposes.

Thanks,

Adnan

Hello Sigurd,

My apologies, I misunderstood the question. Yes the peripherals (GPIO and ADC) from my custom overlay file are indeed represented in the zephyr.dts file. 

Further proof of this is that my control code in main is working. I can control the GPIOs and the read from the desired ADC input.

The kit I am using is the nRF52 DK (nRF52832). I am trying to integrate a camera module and need access to the SPIM and TWIM drivers, hence the original question.

Please advise.

Thanks,

Adnan

Hi Adnan,

Ah, then we know that the devicetree is correct.

The errors below is that Kconfigs are not set.
You can check their dependencies of Kconfig options in VS Code using the Kconfig feature:

Then check the value of the dependencies:

Does this show you what you are missing with your options?

Hi Siguard,

So when I look into the dependencies of the SPIM0 and TWIM1 in the KCONGIH GUI. They are both grayed out, so cannot be selected, and the only thing it says for dependencies is =n.

I need to, some how, enable the NRFX SPIM0 and NRFX TWIM1 drivers to move forward with my project.

Thanks,

Adnan

Hi Adnan,

Does this sample work for you?

It is based on the zephyr UART driver sample

echo_bot_with_i2c_and_spi.zip

Hello Siguard,

So the sample builds, compiles and flashes but I get nothing on the NRF RTT Terminal. A look at the prj.conf file shows 2 problems:

1) CONFIG_NRFX_SPIM0 was assigned the value y, but got the value n. Missing dependencies:

n

2) CONFIG_NRFX_TWIM1 was assigned the value y, but got the value n. Missing dependencies:

n

I am running nRF Connect SDK v2.1.2 with nRF52 DK (nRF52832) eval board: PCA10040, 2.1.0, 2021.02.

Please advise. Thanks!
