IRL: the riddle with a mere oscilloscope!

Yesterday we achieved a new goal : we successfully played an ILDA animation on a mere oscilloscope. We attach a video as an evidence of our performance.

Let’s focus on what we actually did.
We built a program which plays directly an ILDA animation in the ILDA file format. We can set several options directly on the command line such as the time spent per frame and the scaling factor.

We enhanced our code which built an ILDA file from a string or a file. It operates directly on board and is now using an ILDA file per character instead of a SVG file with the whole charset.
We display directly on the board a list of tweets taken from a database and fetched them on the go with the twitter API that we now use in C instead of Python.

The IRL project would be nothing without those huge changes that drew our path since the beginning of the project. And we are proud to announce that we are changing (again) our architecture, and we would like to thank our teachers for their precise suggestions on that topic. In a word we are going to rely on a wishbone bus so as to assure the communication through the entities of the FPGA. In that way, out system will be cleaner plus it will enhance its capabilities.
