What do you mean the I’m planing on using 12 of them so I can have a 360 camera from vision sensors. Also I’m planning on have 2 backup encoders for each wheel encoder so I have a very low chance to not know where I am. Then the rest I’m going to have line sensors drop on the field so I can sense when a ball or robot goes past a certain point.
Think there need to be some fairness in this… “allocation”.
REC just released the VRC Annotated Programming Skills Challenge with worlds spots to be won.
And the deadline is 30 Aug… and nowadays, terms like “in the coming weeks” just do not inspire confidence at all.
So i guess it will be another case of non-US teams not able to get our hands on this useful product in time for the online challenge? And we are supposed to showcase how we are using the different types of sensors…
Question: how would you be able to program any of the sensors through the 3 wire Expander? It’s only using one port on the v5 brain and there are no markings for the different 3 wire ports.
Or am I missing something?
In the new version of VexCode (both V5 and Pro), you can add the 3 wire expander as a smart device. Then, when you go to add a 3 wire device, it will allow you to select whether you are connecting it to the 3 wire ports on the brain or on the expander.
@sazrocks explained practically how to do it. I think what your struggling with is how 1 port can become 8. The answer is that “smart devices” have a little computer inside them, when you talk to a smart device you are not reading a raw sensor etc. The smart device expander handles reading all 8 ports and putting the data together to send to the brain.
Under the hood the 8 ADI ports actually run into a chip and then are treated as a smart port(port 22). The new part is just taking that chip and selling it separately.
