The Operating System - ThreadX • ThreadX is the underlying RTOS in NET+OS • Scalable, high performance, real-time kernel • Developed by Express Logic (www.expresslogic.com) • Included in NET+OS as a library /netos/lib/32b/tx.a • Only objects used are linked to the image • ANSI C compliant • Source code optionally available

The TCP/IP Stack • Stack is based on the >>Fusion<< TCP/IP Stack(former Pacific Softworks) • Protocols: PPP, ARP/RARP, ICMP, IGMP, IP, UDP, TCP, DHCP • Berkeley BSD compliant Socket Interface • Included in NET+OS as a library /netos/lib/32b/tcpip.a • Only objects used are linked to the image • ANSI C compliant

Higher Level Networking Protocols • Easy to use APIs for • POP3 / SMTP • FTP client and server • HTTP • Telnet • SNMP,SNMPv2 • DNS • NTP • Fast IP • Fast UDP void applicationStart (void) { unsigned long rc; unsigned long handle; char to[] = "01739011196@d2-message.de"; //char to[] = "nsso01@marvin.os"; char from[] = "devboard@marvin.os"; char subject[] = "Hi there"; char msg[] = "Howdy."; handle = MCCreate(POP3, 110, "192.168.101.240", \ 25, "192.168.101.240"); rc = MCSendSimpleMail(handle, from, to, subject, msg, strlen(msg)); printf("MCSendSimpleMail returned %d\n", rc); rc = MCClose(handle); tx_thread_suspend(tx_thread_identify()); }

Low Level Code • Board Support Package (BSP) completely available in source, including device drivers for: • Network Interface, Loop Back Device • Serial: UART, SPI, HDLC • DMA • I2C, LCD • USB: Host, Device • Power Save
