Experimenting with open-source TCP/IP stacks on the Goldilocks

Arduino enthusiast and creator of the Goldilocks ATmega1284p Arduino-compatible board Phillip Stevens hasn't rested since the launch of the board, and has now moved on and experimenting with the open-srouce micro-IP (uIP) TCP/IP stack using Ethernet shields based on the new Wiznet W5200 controller IC.

The reason for experimenting is to test the speed improvements with the faster IC, and with some measurement showed a speed increase of up to 36 times the W5100. Furthermore Phillip has demonstrated that the Goldilocks board is an ideal test bed for developing TCP/IP and UDP/IP stack applications. on top of the existing improvements over standard Arduino-compatible boards. 

With the use of logic analyser tools (above) Phillip demonstrates the speed differences possible, and also plans for his next works. To find out more, visit Phillips' interesting website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

Goldilocks is the Arduino-compatible board designed to be not too big, and not too small. It's just right. Using the ATmega1284p MCU gives a significantly more powerful microcontroller than the ATmega328p and ATmega32u4 found in common 8-bit Arduino boards. With more memory and a higher clock speed than standard Arduino boards this may be just what you need to get your project done.

Apart from the better MCU there's also a secondary Atmel ATmega32U2 for USB that can also be programmed in its own right, a resilient 7-28V input voltage range switchmode power supply with up to 2A output for high-current shields - perfect for GSM shields that would normally require an external power supply. Plus an incredible range of I/O options, an onboard 32.768 kHz crystal for RTC needs, microSD socket and much, much more. For more information including a detailed user manual, design files and of course to order - visit the Goldilocks product page
