Build for Swoop?

[dreamchrome]

I'm trying to build ZMK for a swoop with nice nanos and I'm hoping this repo could help. Is there a fork or something that this swoop config works with?

[jimmerricks]

This is for the MX version right?

[dreamchrome]

Yes, MX.

[jimmerricks]

I don't have one handy for MX but you could try the one I made for a Choc version of the Swoop. If it doesn't work straight off, it should give you a pretty good base to tweak.

Thanks so much!

There have been some changes and those builds don't compile anymore with the newest ZMK. I was wondering if there's an updated version that works.

I'm especially interested in the LED configuration since I can't get mine working. I currently have it like this but it doesn't seem to work. Would appreciate any feedback.

#include <dt-bindings/led/led.h>

&pinctrl {
  spi1_default: spi1_default {
    group1 {
        psels = <NRF_PSEL(SPIM_MOSI, 0, 6)>;
    };
  };
  spi1_sleep: spi1_sleep {
    group1 {
        psels = <NRF_PSEL(SPIM_MOSI, 0, 6)>;
        low-power-enable;
    };
  };
};

&spi1 {
  compatible = "nordic,nrf-spim";
  status = "okay";
  pinctrl-0 = <&spi1_default>;
  pinctrl-1 = <&spi1_sleep>;
  pinctrl-names = "default", "sleep";
  // mosi-pin = <6>;
  // Unused pins, needed for SPI definition, but not used by the ws2812 driver itself.
  // sck-pin = <5>;
  // miso-pin = <7>;

  led_strip: ws2812@0 {
    compatible = "worldsemi,ws2812-spi";
    // label = "WS2812";

    /* SPI */
    reg = <0>; /* ignored, but necessary for SPI bindings */
    spi-max-frequency = <4000000>;

    /* WS2812 */
    chain-length = <36>; /* number of LEDs */
    spi-one-frame = <0x70>;
    spi-zero-frame = <0x40>;
    color-mapping = <LED_COLOR_ID_GREEN
                          LED_COLOR_ID_RED
                          LED_COLOR_ID_BLUE>;
  };
};

/ {
	chosen {
		zmk,underglow = &led_strip;
	};
};

This is now working:

#include <dt-bindings/led/led.h>

&pinctrl {
  spi1_default: spi1_default {
    group1 {
        psels = <NRF_PSEL(SPIM_SCK, 0, 5)>,
                <NRF_PSEL(SPIM_MOSI, 0, 6)>,
                <NRF_PSEL(SPIM_MISO, 0, 7)>;
    };
  };
  spi1_sleep: spi1_sleep {
    group1 {
        psels = <NRF_PSEL(SPIM_SCK, 0, 5)>,
                <NRF_PSEL(SPIM_MOSI, 0, 6)>,
                <NRF_PSEL(SPIM_MISO, 0, 7)>;
        low-power-enable;
    };
  };
};

&spi1 {
  compatible = "nordic,nrf-spim";
  status = "okay";
  pinctrl-0 = <&spi1_default>;
  pinctrl-1 = <&spi1_sleep>;
  pinctrl-names = "default", "sleep";
  // mosi-pin = <6>;
  // Unused pins, needed for SPI definition, but not used by the ws2812 driver itself.
  // sck-pin = <5>;
  // miso-pin = <7>;

  led_strip: ws2812@0 {
    compatible = "worldsemi,ws2812-spi";
    // label = "WS2812";

    /* SPI */
    reg = <0>; /* ignored, but necessary for SPI bindings */
    spi-max-frequency = <4000000>;

    /* WS2812 */
    chain-length = <36>; /* number of LEDs */
    spi-one-frame = <0x70>;
    spi-zero-frame = <0x40>;
    color-mapping = <LED_COLOR_ID_GREEN
                          LED_COLOR_ID_RED
                          LED_COLOR_ID_BLUE>;
  };
};

/ {
	chosen {
		zmk,underglow = &led_strip;
	};
};

but it seems to be suffering from this issue.
