Links to Other Embedded and Small Internet Servers
- Stanfords Small Linux Server - One time holder of the worlds smallest webserver title, and the server that has received the most press.
Matchbox Webserver
single-board AMD 486-SX computer with a 66 MHz CPU, 16 MB RAM, and 16 MB flash ROM, big enough to hold a useful amount of RedHat 5.2 Linux including the HTTP daemon that runs the web server
connection to outside world: Null-Modem parallel cable ( PLIP parallel to parallel Linux )
- iPic Webserver - Neat Demo. I hear it uses a very stripped down version of what we at iReady call stateless tcp with precomputed packets in eeprom and very minor header manipulation.
2 chips:
8-Pin, 8-Bit CMOS Microcontroller PIC 12C509; Running over this tiny TCP/IP stack, this chip includes a web-server ( HTTP 1.0 compliant , Telnet )
EEPROM holds webpages
connection to outside world: third chip ( pstn modem -Public Switched Telephone Network PSTN: A circuit-switched analogue network )
- web ace - another iPic like device based on an ultra small microcontroller, source code also available!
Fairchild ACE1101MT8 microcontroller programmed as a Web server and containing two tiny web pages in its on-chip memory
a 57.6Kbps SLIP ( SLIP is Serial Line Internet Protocol. SLIP is used, most commonly, for connecting a computer to a TCP/IP network using a modem. SLIP lets IP packets be sent up and down a serial line. ) line connects the server to a Linux host, which serves as a bridge between SLIP and an ethernet LAN
- Pharlap's PC/104 Based Webserver - not considered small in 1999.
The following is a list of the hardware which is used in the "World's Smallest Web Server":
A PC/104 486SLC Single Board Computer from Real Time Devices and NE2000 Ethernet card from WinSystems
A Weather Monitor II. The Davis weather station attaches to the Real Time Devices CPU board via an RS-232 link.
The following is the software running on this server: The Realtime ETS Kernel from Phar Lap Software The ETS MicroWeb Server from Phar Lap Software The Internet Weather Station application software from Phar Lap Software
HighRel PC-compatible motherboard, only 4 x 4"
3.3 volt 486DX4-100 MHz processor
Two software selectable RS-232/422/485 serial ports Extended Capabilities Parallel Port Configuration EEPROM 256 bits available to user
Floppy and IDE hard drive controllers
ECP/EPP parallel port (see Added Features above)
PC-AT compatible keyboard
runs Windows 3.x,95,NT UNIX...
connection to outside world: modem over serial port.....
- Very Small Linux Capable Server on a 3.5" x 1" simm. ( $240 )
For those interested, the board will have... 16MHz 68EZ328 DragonBall Microcontroller 2Mb FLASH ROM and 8Mb DRAM 18 General Purpose I/O pins (or between 8 and 11 if you use it with a graphic LCD panel). Will directly drive a monochrome LCD panel up to QVGA resolution (320x240) 10Base-T Ethernet RS-232 Serial High speed (1Mbit/sec) I2C or SPI 3 wire serial 3.3Volt low power device. When idle, draws only microamps.
- Tiny InterNet Interface - A simm formfactor internet computer that speaks java. ( $50 )
The TINI™ board is Java™ computer that uses a TINI chip set plus commodity SRAM and interface circuitry in a 68-pin SIMM stick form factor. TINI's three-chip chip set consists of a processor, Flash ROM containing the firmware, and an Ethernet controller.
TINI™ software is divided into categories: run-time code in Flash ROM (the RTOS, TCP/IP stack, Java™ VM and API packages) and high-level networking protocols (FTP, TELNET, DHCP, DNS); development tools (JDK);
connects to outside world: ethernet or serial
- Flatstack - an 8 bit micro internet platform.
It is about half the size of a credit card
FlatStack™ is essentially made up of an 8-bit microcontroller, a clock-signal provider and a memory. FlatStack™ has access to the memory contents of the parent device via the microcontroller's bus saving this data into standard HTML format and transmitting this file via RS232, Ethernet or Ethernet and a modem. File transfer is also possible the other way around: FlatStack™ can receive data from the Internet and communicate it to the electronic device. If mass-produced FlatStack™ will cost somewhere between 5-10 dollars
- Embedded Ethernet - A very nice project that connects AVR's and PIC's to etherent. NOT A WEBSERVER ONLY INBETWEEN MICROCONTROLLER AND ETHERNET
Connect embedded microcontrollers and microprocessors to 10baseT Ethernet using this small (1.5" x 1.8") board with PCB layout
TCP/IP functionallity
- Picoweb - A Webserver based on an NE2000 chip and an AVR processor. ( $50 ) LA JOLLA
The PicoWeb ServerTM allows World Wide Web access to digital I/O and serial I/O signals without the need for assistance from external PCs or Unix computers. It is a stand-alone device with a real-time networking kernel, TCP/IP stack, and an HTTP Web server. Once plugged into a network with Internet access, using it's twisted pair Ethernet connector (i.e., 10baseT RJ-45 plug), the PicoWeb can be accessed via a standard Web browser from anywhere in the world
- scenix Santa Clara, Calif. - Sept. 27,
1999 - Scenix Semiconductor, Inc. today introduced a complete industry-standard
network connectivity protocol stack that is designed to provide
direct Internet access for cost- and size-constrained embedded
applications, such as remote access and monitoring devices, industrial
control systems and Web-enabled appliances. The "SX-Stack" can
communicate with any Web browser on the Internet, and can also receive and
transmit e-mail. Unlike other implementations, the SX-Stack includes the
physical interface layer with the TCP/IP (Transmission Control
Protocol /Internet Protocol) network connectivity protocols, enabling
system designers to produce embedded Internet devices without external
physical access chips or a gateway PC.
The hardware platform for the SX-Stack is the high-performance Scenix SX Series microcontroller (MCU), which can provide up to 100 MIPS (million instructions per second) performance and is priced in the $5.00 range. This offers an extremely cost-effective alternative to other solutions, including the 32-bit processors and ASICs (application-specific integrated circuits) that are generally required for single-chip protocol stack implementation.
- Microchip's Embedded Internet Page - microchip seems to be the first MPU maker that realizes there is a huge market here.
what is PPP, TCp/IP, NFS,RFC,SLIP,SANA ?
