Picking up after where we left a week ago: After some debugging, I’ve been able to start communicating with the charger.   Assuming the hardware-related problems I had to solve before successfully receiving my first CAN packet are rare, I must say that the steps required to actually get packets from the bus and on […]

My TWIKE is definitely ready for our upcoming 11-day, 2500km yearly trip, TDAF2016. This upgrade has been in the making for a very […]
