today we finished to define the list of components we need for our new ball. Among these components, there is an extern wifi antenna, that is not very cool, but we think that the set of LED could be a Faraday Cage and prevents our ball from any wireless connexion.
Then we tried to design our PCB, beginning with CPU, and we realized that is very difficult. Indeed the function of some pins in the CPU are not clear at all for us, while the datasheet considers them as classical and don’t help us. It makes us not efficient and very slow to work, but the more we find it hard, the more we learn.
