This example initializes the rmt driver for only one LED stripe: when creating the config structure for the rmt, it uses RMT_DEFAULT_CONFIG_TX with the gpio used for the stripe. So, I wanted to use more than one stripe, and I did like it is done in FastLED code : put GPIO 0 in ...

这是配置发送的,如果接收数据,要用 rmt_rx_channel_config_t,用起来一样,搞懂一个,另一个就懂了。注意,接收和发送的函数是分布在两个头文件中的,发送是 rmt_tx.h,接收是 rmt_rx.h。因为驱动 WS2812 是输出,属于发送模式,咱们只用 rmt_tx_channel_config_t 结构体。
