Hi all, Asif and Qinglai have already presented two potential hackathon projects: the GDB hard fault handler and the elevator (motor control) demo. Below I'd like to propose another project, which I unfortunately won't be able to fully participate myself. And of course, further project ideas are very welcome; I'd encourage people to present them already before the hackathon here. Project idea: ENC28J60 TCP/IP support for Espruino Espruino is a node.js like JavaScript environment for microcontrollers, running among other things on the STM32F407 MCUs, which we will have a few at the hackathon: http://www.espruino.com http://www.espruino.com/ReferenceSTM32F4DISCOVERY ENC28J60 is an old, inexpensive Ethernet chip, used in the Ell-i Ellduino board. We also have a separate ENC28J60 board, which can be easily plugged in to another board with jumper cables. https://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en022889 The board we have is similar to one from SparkFun, but physically larger than this one: https://www.sparkfun.com/products/765 I think it is this one, but I don't remember any more for sure: http://www.elecfreaks.com/store/enc28j60-ethernet-module-p-121.html Now, thanks to Jose have an WebSockets TCP/IP stack for the ENC28J60, and also the "official" Ell-i IP/UDP/CoAP stack. There are also other TCP/IP stacks that work with ENC28J60, such as the uIP and lwIP stacks. https://en.wikipedia.org/wiki/UIP_(micro_IP) https://savannah.nongnu.org/projects/lwip/ Both of those stacks are clearly bigger than the Ell-i stacks, but they are also more stable. And on the Cortex-M4 MCUs the space is not so much a concern than on the very low end Cortex-M0 ones anyway. The idea of the project would be to take one (or two) of these stacks, make them work on the STM32F407 board with the separate ENC28J60 board, and glue them to the Espruino environment through a preferentially AJAX-style API. Unfortunately I haven't had time to think about this much more. But if anyone is interested, let's talk! --Pekka
