01 Overview
RMT builds the strip waveform.
- Use when: rings, accent lighting.
- Skip when: a single GPIO lamp (Blink/LEDC).
Sensors and I/O
WS2812-class strips. RMT for timing; EMI for certification.

RMT builds the strip waveform.
1. RMT channel and GPIO.
2. Fill GRB buffer.
3. Refresh; do not recompute in an ISR.

用 RMT 发灯带波形。
1. 配 RMT 通道和 GPIO。
2. 写 GRB 缓冲区。
3. 刷新;不要在中断里做重计算。
