- Arduino CALCnet2.2 Network Sniffing
- 28 Dec 2010 03:19:48 am Permalink
So the (eventually) planned globalCALCnet needs a bridge between CALCnet and the rest of the internet, and one possible step in that direction is a piece of hardware that can speak both serial and CALCnet. Based on my previous experience with Arduino linking emulating the TI link protocol, I decided to write an Arduino sketch to send and receive on a CALCnet network. I haven't decided all the specifics about things like pretending to be a single calculator or many calculators, but I did indeed implement successful bit reception, byte reception, and frame grabbing. Check out the following sniff of two (real) calculators running Flourish together. All the lines except the last are ball screen->screen messages, while the last is a quit broadcast from pressing [clear] on one calculator. More on this tomorrow.
