Arduino fans can now take their hacking projects to a new level with the release by the Arduino crew of their WiFi shield. The shield is designed around an Atmega 32UC3 32bit microcontroller which controls the WiFi stack and the … Read more
Michael Fischer of emb4fun has a new tutorial on using Nut/OS on Altera FPGAs. His design uses the Altera DE0-Nano board and a self-made adapter equipped with a DM9000E-H board, and includes a short example for an Internet Radio. Michael’s … Read more
Martin Lormes recently acquired an Arduino and Ethernet shield. Once he got the setup running on the web using the Webduino Arduino web server library, he checked the traffic using Wireshark and noticed that if the embedded server didn’t offer … Read more
While most of us are familiar with packet capturing/sniffing programs such as Wireshark, it’s not always the most convenient or appropriate tool to use in every network monitoring situation. Henry Van Styn has written an excellent how-to tutorial on the … Read more
O’Reilly is offering a free webcast on “Core Network Protocols: Two techniques you need to know.” The 60 minute presentation by Bruce Hartpence will be live this Friday, October 14, 2011, at 1 PM PT. In this webcast we’ll talk … Read more
firestorm_v1 from yourwarrantyisvoid has published this detailed tutorial on building and using a passive ethernet tap. His goal in this project is to facilitate network monitoring for intrusion detection purposes, and wanted hardware which will allow the monitoring for traffic … Read more
The uIP TCP/IP stack for the web platform now lists and reads files from an SD card. You can now read files and list directories from the SD card. There’s also a ‘sddump’ command that will dump sectors from the … Read more
There’s some new features in Bonybrown’s uIP TCP/IP stack project for the web platform. Some notable changes are: The code runs 3 “tasks” that it multitasks between. One for the IP stack, one for the serial port (debugging help) and … Read more
Another update on the uIP TCP/IP stack port for the web platform. Bonybrown has added even more features: Periodic uIP processing now works, driven from RTCC alarm interrupt (500mS). Added start for simple round-robin co-operative task switcher. Latest code is … Read more
Here’s another update on the uIP TCP/IP stack port for the web platform. Bonybrown got the uIP stack to work with interrupts from the ENC28J60, and used DMA to transfer buffers to PIC memory. Performance wise – no real difference … Read more
A few months ago we started a port of the uIP TCP/IP stack for the dsPIC33-based web platform. Bonybrown picked up the source and got it working. The current version can accept 10 simultaneous telnet connections, and has ping times … Read more
