arduino_uip

• Fix rare checksum error introduced by commit https://github.com/ntruchsess/arduino_uip/commit/38c5e7e91e3cd380e7f4a4cb18da53d443b93b11
• save 54 bytes of flash compared to version 1.08

extended version of UIPEthernet_1.09:
(contains functionality that is not part of official Ethernet-api)

UIPClientExt: nonblocking connect, read of local- and remote port
UIPServerExt: returns instances of UIPClientExt
example code: https://github.com/ntruchsess/arduino_uip/blob/ext/examples/NonBlockingTcpClient/NonBlockingTcpClient.ino

same as UIPEthernet_v1.09 but for Arduino-IDE Version 1.5.5 and higher

• Decrease TCP response-time by implementing a per-client send timer (configurable via define UIP_CLIENT_TIMER in utility/uipethernet-conf.h)
• Fix ENC28J60 receivebuffer overflow caused by invalid handling of wraparound
• Fix ENC28J60 crash caused by sending zero-length packet

same as UIPEthernet_v1.57 but for Arduino-IDE Version 1.5.5 and higher

extended version of UIPEthernet_v1.08:
(contains functionality that is not part of official Ethernet-api)

UIPClientExt: nonblocking connect, read of local- and remote port
UIPServerExt: returns instances of UIPClientExt
example code: https://github.com/ntruchsess/arduino_uip/blob/ext/examples/NonBlockingTcpClient/NonBlockingTcpClient.ino

• reduce flash footprint
• add powerOff, powerOn, getrev and linkStatus to Enc28J60 class
• add Print::write and Print::print to UIPClient and UIPServer
• fix a leak of connections (tcp)
• auto-free udp-blocks.

extended version of UIPEthernet_1.07:
(contains functionality that is not part of official Ethernet-api)

UIPClientExt: nonblocking connect, read of local- and remote port
UIPServerExt: returns instances of UIPClientExt
example code: https://github.com/ntruchsess/arduino_uip/blob/ext/examples/NonBlockingTcpClient/NonBlockingTcpClient.ino

same as UIPEthernet_v1.07 but for Arduino-IDE 1.5.5

• same as UIPEthernet_v1.06 but for Arduino-IDE 1.5.5

• fixed DNS not working if DNS is not same ip as router (#43)
• fixed NTP not working if not using DHCP, UDP not working if ARP is not yet resolved. (all fixed in #45)
• fixed race-condition in UIPClient::close() causing leak of connection-associated memory (#44)
• stabilize UDP potentially using to much memory(https://github.com/ntruchsess/arduino_uip/commit/6aed921a9cf298ba42bedf036dfc8d1cfb7d35ee)
• fixed various compiler-warnings (#46, #48, #49).
• saved nearly 500kb of Flash (when using both TCP and UDP)

fixes for #27 and #28

Fixes for #27 and #28

This release supports the 1.5rev2 library-format as specified in https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification
Tested on Arduino 1.5.5

To install UIPEthernet into your Arduino 1.5.5 download and unpack the src-zip (or tar.gz). Then choose 'Sketch'->'import Library'->'add Library' from the menu. In the dialog that opens navigate to the directory where you unpacked the source-zip. Select the folder 'UIPEthernet' that was contained the source-zip and click 'open' to install.

• use static (allocated by declaration) instead of dynamic memory.
• fix use of other values for ENC28J60_CONTROL_CS in Enc28J60Network.h

• this release is based on the 'static-memory'-branch.

This release contains features that are not (yet) included in the stock Ethernets lib API, so they remain subject to change when they eventually will be merged into master.

this adds operator==, localPort, remoteIP and remotePort to EthernetClient

pull-request against stock Arduino: https://github.com/arduino/Arduino/pull/1700

and here an example of its use: https://github.com/ntruchsess/arduino_uip/blob/experimental/examples/AdvancedChatServer/AdvancedChatServer.ino#L70

memory-pool-size for enc28j60-internal ram is now based on number of configured connections and maximum number of packets per connection.

UIPClient.write() is now blocking if UIP_SOCKET_NUMPACKETS are ready to send (waiting for ACK). Number of reattempts is configurable.

Configure in utility/uipethernet-conf.h

/* for TCP */
UIP_SOCKET_NUMPACKETS 5
UIP_CONF_MAX_CONNECTIONS 4

/* for UDP */
UIP_CONF_UDP 1
UIP_CONF_BROADCAST 1
UIP_CONF_UDP_CONNS 4
UIP_UDP_NUMPACKETS 5

/* number of attempts on write before returning number of bytes sent so far /
/ set to -1 to block until connection is closed by timeout */
#define UIP_ATTEMPTS_ON_WRITE -1
