Spinneret Web Server (#32203)

The Parallax Propeller microcontroller teamed with the WIZnet W5100 Ethernet controller provide an ideal chipset for low-cost, low-power embedded Ethernet applications. The Propeller microcontroller's multicore architecture and the W5100's hardware Ethernet stack allow a new level of parallelism and data throughput for robust and reliable embedded network applications. The Spinneret Web Server may be small—at less than 1½ by 4 inches—but it is a feature packed development platform. The built-in MicroSD card socket and real-time clock allow ample room for time-stamped file and data storage, and the oversized EEPROM can store non-volatile data for use when there is no MicroSD card present. As an open-source hardware design, all design files—including layout, schematics, and firmware—are available under licenses that allow free distribution and reuse.

This means that the Spinneret Web Server's design can be incorporated into new applications royalty free and without a non-disclosure agreement.

Synopsis

The Spinneret Web Server is an Ethernet-based development board for the Propeller microcontroller. Web page content, files, and logs can be stored on a MicroSD card. The serial EEPROM has 32 KB for storing a Propeller program and 32 KB for non-volatile data storage, independent of the MicroSD card. There is a real-time clock controller for timestamping files and events and a backup capacitor that will keep the clock running through extended power outages. There is a serial programming header and there are two auxiliary I/O connections: one is a header for level-shifted open-collector communications over a threepin data/power/ground cable, and the second is a 12-pin socket for direct 3.3 volt I/O connections. There are eight status LEDs on the PCB, two of which are repeated on the Ethernet jack. One of the status LEDs is user controllable and shares an I/O pin with a button that can be read under user control. A second button resets the Propeller to reload any firmware from the EEPROM.
