Detailed Description

Pipes code.

Byte pipes.

Operation mode

A pipe is an asynchronous communication mechanism.
Operations defined for mailboxes:

  • Write: Writes a buffer of data in the pipe in FIFO order.
  • Read: A buffer of data is read from the read and removed.
  • Reset: The pipe is emptied and all the stored data is lost.
Precondition
In order to use the pipes APIs the CH_CFG_USE_PIPES option must be enabled in chconf.h.
Note
Compatible with RT and NIL.
