xobs | "One with a timer" It depends. Lately I just go for bit-banging, which if you're running a cheap cheap Cortex-M0+ with Fast GPIO means you get cycle-accuracy that's good enough to bit-bang USB. | 01:37 |

xobs | I say this because we did a project that drove WS2812b with Stupid DMA Tricks, and it would desync after a while due to weird phase drifts. You might not get that with a timer, but if it's just status LEDs then you probably can afford stopping the world to update LEDs. | 01:39 |
CarlFK | huh. I want one and only one obvious solution. | 01:44 |
