Motor command :
This week-end I worked on the PCB will command the motor. It is now finished. We will use a AT90USB162 as micro controller.
Power problems :
We have finally solve our power management problem : indeed, in the propeller we need 1.2V, 1.8V, 2.5V, 3.3V, 5V(with almost 10A for 5V).
I thought about the internal architecture of our FPGA. My idea is the following :
As sensor, we will use a coding wheel. But, we have put on the propeller an halls sensor too, just in case …..
