# ioLibrary Driver The ioLibrary means “Internet Offload Library” for WIZnet chip. It includes drivers and application protocols. The driver (ioLibrary) can be used for the application design of WIZnet TCP/IP chips as [W5500](http://wizwiki.net/wiki/doku.php?id=products:w5500:start), W5300, W5200, W5100 [W5100S](http://wizwiki.net/wiki/doku.php?id=products:w5100s:start). ## ioLibrary This driver provides the Berkeley Socket type APIs. - Directory Structure <!-- ioLibrary pic -->  - Ethernet : SOCKET APIs like BSD & WIZCHIP([W5500](http://wizwiki.net/wiki/doku.php?id=products:w5500:start) / W5300 / W5200 / W5100 / [W5100S](http://wizwiki.net/wiki/doku.php?id=products:w5100s:start)) Driver - Internet : - DHCP client - DNS client - FTP client - FTP server - SNMP agent/trap - SNTP client - TFTP client - HTTP server - MQTT Client - Others will be added. ## How to add an ioLibrary in project through github site. - Example, refer to https://www.youtube.com/watch?v=mt815RBGdsA - [ioLibrary Doxygen doument](https://github.com/Wiznet/ioLibrary_Driver/blob/master/Ethernet/Socket_APIs_V3.0.3.chm) : Refer to **TODO** in this document - Define what chip is used in **wizchip_conf.h** - Define what Host I/F mode is used in **wizchip_conf.h** ## Revision History * ioLibrary V4.0.0 Released : 29, MAR, 2018 * New features added: Library for W5100S added. * ioLibrary V3.1.1 Released : 14, Dec, 2016 * Bug fixed : In Socket.c Fixed MACraw & IPraw sendto function. * ioLibrary V3.1.0 Released : 05, Dec, 2016 * Internet application protocol add to MQTT Client (using paho MQTT 3.11) * ioLibrary V3.0.3 Released : 03, May, 2016 * In W5300, Fixed some compile errors in close().
