* \defgroup clock Clock interface
|
||||
*
|
||||
* The clock interface is the interface between the \ref timer "timer library"
|
||||
* and the platform specific clock functionality. The clock
|
||||
* interface must be implemented for each platform that uses the \ref
|
||||
* timer "timer library".
|
||||
*
|
||||
* The clock interface does only one this: it measures time. The clock
|
||||
* interface provides a macro, CLOCK_SECOND, which corresponds to one
|
||||
* second of system time.

/**

* \defgroup psock Protosockets library
|
||||
* @{
|
||||
*
|
||||
* The protosocket library provides an interface to the uIP stack that is
|
||||
* similar to the traditional BSD socket interface. Unlike programs
|
||||
* written for the ordinary uIP event-driven interface, programs
|
||||
* written with the protosocket library are executed in a sequential
|
||||
* fashion and does not have to be implemented as explicit state
|
||||
* machines.
|
||||
*
|
||||
* Protosockets only work with TCP connections.
|
||||
*
|
||||
* The protosocket library uses \ref pt protothreads to provide
|
||||
* sequential control flow. This makes the protosockets lightweight in
|
||||
* terms of memory, but also means that protosockets inherits the
|
||||
* functional limitations of protothreads. Each protosocket lives only
|
||||
* within a single function. Automatic variables (stack variables) are
|
||||
* not retained across a protosocket library function call.
|
||||
*
|
||||
* \note Because the protosocket library uses protothreads, local
|
||||
* variables will not always be saved across a call to a protosocket
|
||||
* library function. It is therefore advised that local variables are
|
||||
* used with extreme care.
|
||||
*
|
||||
* The protosocket library provides functions for sending data without
|
||||
* having to deal with retransmissions and acknowledgements, as well
|
||||
* as functions for reading data without having to deal with data
|
||||
* being split across more than one TCP segment.
|
||||
*
|
||||
* Because each protosocket runs as a protothread, the protosocket has to be
|
||||
* started with a call to PSOCK_BEGIN() at the start of the function
|
||||
* in which the protosocket is used. Similarly, the protosocket protothread can
|
||||
* be terminated by a call to PSOCK_EXIT().

|

* @{
|

*
|
||||
* The basic uIP TCP implementation only allows each TCP connection to
|
||||
* have a single TCP segment in flight at any given time. Because of
|
||||
* the delayed ACK algorithm employed by most TCP receivers, uIP's
|
||||
* limit on the amount of in-flight TCP segments seriously reduces the
|
||||
* maximum achievable throughput for sending data from uIP.
|
||||
*
|
||||
* The uip-split module is a hack which tries to remedy this
|
||||
* situation. By splitting maximum sized outgoing TCP segments into
|
||||
* two, the delayed ACK algorithm is not invoked at TCP
|
||||
* receivers. This improves the throughput when sending data from uIP
|
||||
* by orders of magnitude.
