chan
Threads often communicate over channels. The producer thread or isr writes data to a channel and the consumer reads it. The may be multiple producers writing to a single channel, but only one consumer is allowed.
In the first example, thread 0 and thread 1 communicates over a channel. thread 0 writes data to the channel and thread 1 read the written data.
