Thanks for the update, and thanks for pointing out the documentation error. This has now been addressed in this PR: https://github.com/nrfconnect/sdk-nrf/pull/11282

That was it! Thank you very much.

I find it interesting that the inverted version worked in a previous version of the SDK, how strange.

It might be worth updating the PMW3360 Driver page. While I understand that this is an exemplary configuration for the DTS, it seems illogical for the driver page to possess a distinct configuration for the chip select.

Once again, Thank you.

The chip select line for PMW3360 is set as active high ('0' == GPIO_ACTIVE_HIGH) in your board file here: https://github.com/deslobodzian/MouseSoftware/blob/73872f3a0dc21b49b165c848b916952fa3e0e1ed/Mouse_Software/boards/arm/mouse_board/mouse_board.dts#L73 but it should be active low according to the datasheet. Maybe this is the problem.

Try to change 'cs-gpios = <&gpio0 6 0>;' to cs-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;

Logic trace after setting CS as active low:

There is no response here as I don't have the sensor connected.

Main branch is not, “complete-rework” is the up to date branch. Sorry about that.

Is this project up to date? I got several build errors when I tried to build it with SDK 2.3.0

I'm using a custom board I built. Here is the software that is currently running on the system. I can share the schematics If needed but I reckon if It works on an older version of the SDK it should be a design issue.

Hello,

I can't think of any breaking changes that were made to SPI between versions 2.0.2 and 2.0.3, but something is clearly different. I noticed from the last log you posted that there is no communication happening between the sensor and the nRF.

Would you be able to share your project here so that I can take a look, or are you testing it with an SDK sample? Additionally, it would be helpful if you could use a logic analyzer or a scope to check what's happening on the bus.

Thanks,

Vidar
