  • I was playing around with the PAN1780 eval kit (it mimics the nRF52840DK closely except for the lack of QSPI) and I seem to have issues with neopixel.

    Has anyone been able to get an nRF52840 working with neopixels? Doing something like

    require("neopixel").write(D28, [255,0,0]);
    

    seem to lock up the board. The web ide console (connected through ble) stops responding, and a blinky I have running to check if the board was still actually working behind the scenes stops blinking. It doesn't seem to matter whether I have a neopixel connected or not.

    Here's what I use for testing this:

    let on = 0;
    
    const toggle = () => {
      on = !on;
      digitalWrite(LED1, on);
    };
    
    setInterval(toggle, 100);  
    
    setTimeout(()=>{
      require("neopixel").write(D28, [255,0,0]);
    }, 1000);
    

    I have an actual nRF52840DK arriving sometime next week so I can see if it's just this particular board that's the problem, but I wanted to see if anyone has had success with neopixels on any kind of board that has the nRF52840 (like the particle boards for example)
