That's correct, I no longer need help with this ticket.

Thanks

Thanks Michal

Don't worry about points 1 and 2, I figured it out, its a bit ugly at the moment, so I can't post it.

in the ui_module.c of the asset tracker app. I just added an extra call to my own functions so the original LEDs are still doing whatever..

/* Static module functions. */
static void update_led_pattern(enum led_state pattern)
{
#if defined(CONFIG_LED_CONTROL)
    struct led_state_event *event = new_led_state_event();

    event->state = pattern;
    APP_EVENT_SUBMIT(event);
#endif
    LOG_INF("LED Pattern is now %d",pattern);
    ws2812_update(pattern);

}

Regards Marshall

Hello Marshall,

I have at least an answer for the question 3., the rest will require some further research.

Unfortunately it is a hardware limitation that the SPI hardware block locks the pins. On the other hand Nordic's PWM driver allows for sending a bit sequence, so that may be something to consider trying instead, if the number of used pins is critical.

The only issue is that you will have to use the nrfx driver and not the zephyr one.

Best regards,

Michal
