Ergodox Infinity LED Programming
« on: Thu, 23 May 2019, 07:57:43 »
Hello all! This is my first post here. I am building my first Ergodox Infinity and I am going to be soldering in the 3mm flangless single-color LEDs that the PCB and Cherry MX switches support. I have already programmed a four layer keymap using the Input Club configurator. However, while it allows you to change the brightness of all of the LEDs together, I cannot find any way to set the LEDs on or off per-switch or per-layer. I read the documentation from IC on the built in LED control and it looks like this should be possible, but I admit I'm starting to get out of my depth. If it's a matter of making specific changes to code in specific files I can do that, but I will need fairly specific instructions. I've tried searching this and other forums, the support forum for Kono, and just about anywhere else I could think to look and couldn't find anything.

My general goal is to have only the active keys lit when I change layers. I'm willing to specific whether an LED for a given key should be on and off individually for each key, for each layer, I just need to know how to do that, or if it is truly possible. Hopefully some of you have some experience/insight into programming LEDs!

Thank you so much for your help! I'm really excited about this build.

As a follow-up, I dug into the MDErgo1-Default-0.kll and found the following:

U"FUNCTION5" : ledControl( 0, 15 );

U"FUNCTION4" : ledControl( 1, 15 );


These correspond to my assignments to the left hand function keys 4 and 5 respectively, to make the LED backlighting brighter (U"FUNCTION4") and darker (U"FUNCTION5"). I don't know enough about the code to know whether the resulting information eg: ledControl( 0, 15); actually provides any useful insight into how to program more complicated LED controls. Complete ignorance. But lets take a more generic key for example.

U"ESC" : U"6";

Can I add to the code to tell it how to control a specific LED as well? Again, not a coder and apologize for my ignorance, but could I do something like this:

U"ESC" : U"6" : ledControl(0);

In this pretend scenario I imagine that ledControl(0) means on and ledControl(1) would mean off, and that this command would only control the LED attached to that switch. Obviously there are a lot of broad and unfounded guesses here, just hoping somebody has some insight lol.




Edit: I found code that looks like it relates to the LED controller in the following files
Left_kiibohd.dfu.bin
left_kiibohd.secure.dfu.bin
right_kiibohd.dfu.bin
right_kiibohd.secure.dfu.bin

Unfortunately I'm having a lot of trouble reading the files as the fonts are not displaying properly. I'm at work and don't have privileges to install something like Notepad++ which would hopefully make it easier. I will try to check that out later. Meanwhile I have attached those files in case anyone is willing to look at them and see what they see.

Thanks!


Edit: I pulled the JSON code for a single switch, in case that helps at all. You can see the different values for the different layers, is there a way to also trigger the LED per layer per switch using this code? Thanks.

        {
            "code": "0x0C",
            "x": 22,
            "y": 6,
            "w": 4,
            "h": 4,
            "layers": {
                "0": {
                    "key": "Y",
                    "label": "Y"
                },
                "1": {
                    "key": "#:None",
                    "label": "NONE"
                },
                "2": {
                    "key": "#:None",
                    "label": "NONE"
                },
                "3": {
                    "key": "T",
                    "label": "T"
                }
            }
        },


Edit Again:

I promise I'll stop after this. At the very bottom of that same JSON file I see the following code, which looks promising


    ],
    "leds": [

    ],
    "custom": {

    },
    "animations": {
        "all_on": {
            "settings": "start, pfunc:interp",
            "frames": [
                "P[c:0%](255), P[c:100%](255)"
            ]
        }
    }
}
