The SEVENSTAX TCP/IP stack was conceived for units which require small amounts of data (in an order of a few hundred kilobytes) such as the download of parameters, web pages, software, or configuration data via Internet, remote service and control.
Advantages
- fast integration and minimal development time frame required. Only those functions necessary for operation are integrated
- easy integration into existing software because of simple interface
- high security through clearly defined functional structures
- tested in Germany, USA, Asia and South America
- asynchronous performance also without OS multi threading capability
- suitable for use in micro controllers from 8...32 bits
- written in ANSI C
- small memory footprint
Specials
- UDP (User Datagram Protocol) and ICMP (ping) support
- NTP (Network Time Protocol) included
- Server functionality
- configurable number of simultaneous TCP connections
- operates with CMX-RTOS from CMX Systems and embOS from Segger Microcontroller Systeme
- needs no special send/receive buffer, using the capacity of the lower network protocol layers
Requirements
- ROM: 2,6...8.2 kbytes code (16- bit CPU), depending on the chosen options
- RAM: 95...250 bytes for variables
- CPU load less than 5 % (16-bit CPU, 10 MHz, data transmission via modem, 14400 baud connect)
- 32-bit timer/counter with an resolution of 1ms
