}rmt_tx_channel_config_t; 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。 不要...

What we can do however is create a queue (or a ring buffer) which the application will use to feed rmt_item32_t type data into the transmit routine. ISR will get values from the queue and write them into TX buffer. Application can create a task which will do blocking writes to the...
So I thought the filter threshold in the rx_config could be wrong - it is set to 100, assuming the regular bit will have at least double that ticks. The documentation is a bit unclear to me here: In receive mode, channel 0-7 will ignore input pulse when the pulse width is smaller...
