i gave it A=1, B=-1, C=-12, and the result was X1=-3, X2=4.
WHAT IS THIS WITCHCRAFT???
You don't have to get them to work, they just work. Here's an example setup: id:2305316. If they don't work despite having them in a similar setup, you may have rotated them (don't do that, that's why there are four different ankles for the four different cases you might need), or enabled Heat Simulation (which in fact affects the R2 rather than the ankles, but still gives the overall impression of not working).
how to i get the io joints to work?
Also, this finally surpassed the R1 in terms of votes.
Eh it's not the data throughput that's problematic. I mean, yeah it is, but workarounds exist, like for example the buffer you had in mind. By too fast I meant that the touchpad is a device that implies way more interactivity than the R2 can handle, and you can't work around that with hardware. That said, sure, I can wire it up to the R2 just fine, so if you wanna try yourself at doing something fun with it, be my guest.
That's awesome! If the touchpad is too fast, would coordinates in a buffer and sending them as they are queried work?
@Cool4Cool: That's not the one on my list but I guess that can be done too. Beside my touchpad which is probably too fast for this thing, all the peripherals you mentioned are totally doable.
