nope
Although in newer ncs releases they added a RGBW -color LED.

Hi,

Is the bi-color feature implemented in CAF led module?

Thanks

Hi,

The developer was on holiday when this case was originally made, and unfortunately it took a while for work to begin on this feature.
I have been told that he is working on adding this feature if possible.

any update on this?

so people can use a bi-color led on the pcb?

Thank you, I will pass it along when the developer returns.

Hi Oivind

In the file <ncs root>nrf\subsys\caf\led_effect.h
there is a multi-channel color count
#define _CAF_LED_COLOR_CHANNEL_COUNT 3

So I can undef and redefine this into the value 2 (for a bi-color led)

But unfortunaltly in the file <ncs root>nrf\subsys\caf\modules\leds.c
the above define is not used (but replaced by a hardcoded value)
__ASSERT_NO_MSG((led->color_count == 1) || (led->color_count == 3));

It seems this is technical debt to be solved to support improved flexibility for multi-channel colored LEDs.

Ok, the developer is currently on holiday, and will look into a possible solution when he returns next week.

I did made a "custom SDK" this is a typical so called zephyr extended library contains re-usable modulair flexible components.

The components are my (custom) building blocks for several applications I made in different (client) projects.
Each component has a kconfig and cmakelist.txt next to source code file and header file.

Depending on the board configuration and the build configuration in the project
the components will be enable or disabled based upon the multiple boards definition in the project.

I do like run / test my application on multiple vendor boards (stm32F411 nucleo / nordic 52840DK and a nxp board. ;-)

So what i try to solve is the limitations of the CAF LED module in a correct manor without adapting the source code of the CAF LED module (and button module) each time Nordic release a new ncs version.

Hello Oivind

When I run the sample, after I adapt the board configuration with a Red + green pwm led output)

The debugger hits the assert in the code at line 186 (it looks as intended by design to support 1 or 3 colors only :-)

__ASSERT_NO_MSG((led->color_count == 1) || (led->color_count == 3));

Hence my question to proper adapt the Nordic module without migrate each time Nordic release a new ncs version.

kind regards,
nRF5xFanBoy

Hi,

It is unfortunately not possible to "disable" one of the colors. I have asked one of the developers whether this is something we can add support for. I have not tested this myself, but have you tried implementing it as 2 monochromatic LEDs?

For your second question, what are you trying to do exactly? What is the issue you are trying to solve? What do you mean by "custom SDK"?
