Maybe I have in mind FrameworkComputer/EmbeddedController/pull/12, source: Benjamin-Loison/cinnamon/issues/67#issuecomment-2146256288.

I am just doubting about FP_BREATH_OFF.

grep -rw 'FP_LED_LOW'

Output:

led.c:38:#define FP_LED_LOW 15
led.c:394:		led_level = FP_LED_LOW;

So FP_LED_OFF seems legitimate.

grep -rwn 'FP_LED_BRIGHTNESS_LOW'

Output:

led.c:345:		case FP_LED_BRIGHTNESS_LOW:
led.c:393:	case FP_LED_BRIGHTNESS_LOW:
host_command_customization.h:187:	FP_LED_BRIGHTNESS_LOW = 2,

So FP_LED_BRIGHTNESS_OFF seems legitimate.

I would be curious what 1 instead of 0 visually look like, it may be enough as in #13.

I am just a bit fearing not clearly seeing whether or not the laptop is sleeping or not for power consumption and privacy.

grep -rwn 'FP_BREATH_LOW'

Output:

led.c:40:#define FP_BREATH_LOW 20
led.c:346:			breath_led_level = FP_BREATH_LOW;
led.c:395:		breath_led_level = FP_BREATH_LOW;

So FP_BREATH_LOW looks legitimate.

grep -rwn 'BREATH_ON_LENGTH_LOW'

Output:

led.c:33:#define BREATH_ON_LENGTH_LOW	90
led.c:347:			breath_led_length = BREATH_ON_LENGTH_LOW;
led.c:396:		breath_led_length = BREATH_ON_LENGTH_LOW;

I would say that no matter if setting breath_led_length to 0 or infinity makes sense, the period would just be about varying from 0 (as far as I know) to 0, so doing it correctly is less important. We can just hope that there is no hidden condition looking for such edge case and going on with an unusual procedure.

So how to compile now?

Looking at the mentioned commit/6833f5e098e3198883693c73e527c3525f0cd1e5 (source: FrameworkComputer/EmbeddedController/issues/11#issue-1160860328), it seems fine.

ls

In the context of #13 I use:

sudo EmbeddedController/build/hx30/util/ectool pwmsetkblight 1

So I should figure out if hx20 or hx30 is appropriate for my Framework 13.

blob/553827caae7134d45a0617af9c201e333eab9a26/README.md#framework-laptop-ec

grep 'model name' -m 1 /proc/cpuinfo

model name	: 12th Gen Intel(R) Core(TM) i5-1240P

So hx30 is appropriate in my case.

Should seriously consider the warning (blob/553827caae7134d45a0617af9c201e333eab9a26/README.md#warning) that this may break my laptop. Is there any way to revert the change if it breaks things?

In hx30:

Maybe have to consider:

The output artifact is build/hx20/ec.bin which can be flashed to the EC SPI flash ROM.

EC probably refers to Embedded Controller
SPI probably refers to Wikipedia: Serial Peripheral Interface

EC Flash configuration

When flashing the EC for Framework Laptops with Intel 11th Gen Core Processors, do not erase or overwrite the sectors 0x3C000 to 0x3FFFF, or 0x79000 to 0x7FFFF.

Currently the EC only runs from the ro region.
00000000:00000fff bootsector
00001000:00039fff lfwro
00040000:00078fff rw

Source: EmbeddedController/blob/553827caae7134d45a0617af9c201e333eab9a26/README.md?plain=1#L44-L53

until EmbeddedController/blob/553827caae7134d45a0617af9c201e333eab9a26/README.md#embedded-controller-ec they do not seem to explain how to actually flash. Maybe should investigate the BIOS and similar menus.
