    I'm using this library https://github.com/marcmerlin/FastLED_NeoMatrix/ to do 2D drawing and text on WS2812B leds arranged in a matrix. I suspect you could map your LEDs to a grid with it.

    Platformio is working great for me on macOS for Teensy 4.0 development. My recollection is that the toolchain is missing stuff for some ARM linux distributions, not sure about x86.

    Looking at the datasheet for the RT1060 , the current consumption of the crystal oscillator is about 6.5uA (p.32) plus the RTC consumption of 20uA for the SVNS (p.26). So, 29uA sounds about right.
