TWIKE 560 Adventures

dreifels, the company founded by the three people responsible for creating the vehicle in 1986 have recently moved from sissach to gelterkinden, switzerland.

their new hq (see above rendered picture, since i forgot to take a picture myself) is, obviously, an extremely energy efficient building. they combine many interesting technologies plus an avangarde-style bus-based management system which even controls which kind of music can be heard in any given room.

anyway, i wasn’t there for sustainable architecture 😉

during the last few years, founders peter, ralph and christian have been very open towards my requests / questions / challenges / crazy ideas.

today, our task is to debug some code regarding a sms-module which does not work for some users, review and amend some code regarding the output TWIKE controllers send to the outside world whilst running. i am currently planning to implement a prototype release 2 functionality version of TWIKE-hardware capable to interface with a server via the internet. furthermore, we will be copying about 12 months worth of TW560 log data. this will serve as a base for my server/smartphone visualization concepts which – over time – will be provided by the TWIKE in real-time.

we get started sometime after 1000. peter and i pour over the code and change some parameters and extend the code. it is very interesting to see the source code and being able to influence what is going on. this reminds me of the long-gone period when my family had a semi-prototype 100% ev renault kangoo (serial number 158!) 2004 and i was able, thanks to my fluent french, to tell the engineer at renault’s r&d what needed to be changed in the controller software there! i miss those days.

peter and i go further and create some additional code to accomodate my needs.

we change some parameters and some traditional displays and test on the official TWIKE testbed.
every re-run requires the controller to be re-flashed.

TW560’s micro-controller piggyback pcb is removed from the vehicle and is plugged into a virtual environment.

we work all morning and afternoon and are able to finish all tasks late afternoon.

i’m ready for following input from the controller…
