Since a few days, the Expelliarose team has worked on the schematic design of our card. Now, most of the components that we have ordered are available in the Expedition PCB libraries and thus, we can start placing and routing them. We will also have to choose the shape of our PCB, which will probably be a bit special, because it has to match with our wand design.
At the same time, I have begun to get more familiar with ChibiOS and the STM32 processor thanks to the Olimex board. I currently deal with the PWM control to manage easilly the LEDs intensity.
