Re: [E-puck-user] extension data
Dear Jenny, If you look to the signal page (list of names) of the signals you can see that y0 to y7 go to the camera. This is the parallel camera bus and cannot be used for generic extensions. It can be used to connect other cameras. To connect an extension the most elegant way is the i2c bus, but you can also use some direct pins of the processor by removing the existing functionality. This can be done on the signals that go and come back from the extension (top connector on the extension connector pages). Using the i2c bus you do not remove functionalities, but you need a device on the extension supporting the bus. There is no doc about how to make an extension I hope this helps.

[E-puck-user] extension data
Hi, I'm looking into making an extension board for the epuck and I was wondering about the data that's transferred through the connectors. Some of the connector pins are labelled y0 to y7 which I can't find any information about. What data is transferred on these pins? Can I use them with my extension board? How is data sent and received along these connections? It looks like the omnidirectional vision turret uses these pins but the other extension boards use the i2c bus. More generally, is there any information about making an e-puck extension apart from the schematics for the existing ones? I have looked but not found anything.
