<h1>The uIP TCP/IP stack</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
|
|
uIP is an implementation of the TCP/IP protocol stack intended for small 8-bit and 16-bit microcontrollers.
|
|
<p>
|
|
uIP provides the necessary protocols for Internet communication, with a very small code footprint and RAM requirements - the uIP code size is on the order of a few kilobytes and RAM usage is on the order of a few hundred bytes.

Because not all architectures for which uIP is intended has native 32-bit arithmetic, uIP uses an external C function for doing the required 32-bit additions in the TCP protocol processing. This function should add the two arguments and place the result in the global variable uip_acc32.<p>

Connect to a remote host using TCP.

<p>
|

This function is used to start a new connection to the specified port on the specied host. It allocates a new connection identifier, sets the connection to the SYN_SENT state and sets the retransmission timer to 0. This will cause a TCP SYN segment to be sent out the next time this connection is periodically processed, which usually is done within 0.5 seconds after the call to <a class="el" href="a00147.html#g8096b0c4b543dc408f4dd031ddae7240">uip_connect()</a>.<p>

The length of the packet in the uip_buf buffer.
|
|
<p>
|
|
The global variable uip_len holds the length of the packet in the uip_buf buffer.<p>
|
|
When the network device driver calls the uIP input function, uip_len should be set to the length of the packet in the uip_buf buffer.<p>
|
|
When sending packets, the device driver should use the contents of the uip_len variable to determine the length of the outgoing packet.
