<p>LIN bus isn't masterless though, if I recall correctly.<p>That's the nice thing about CAN: every node is equal, and every node can send a message whenever it wants. As far as I know, LIN doesn't do that: you have one node on a given LIN network that initiates all communication, much like I2C, and the most other nodes can do is reply.<p>It's fine for what it is, of course, it's just missing some things that I think make CAN really neat.</p>

<p>I really, really wish that CAN had caught on more for sensor networks in the hobbyist community.<p>It's so much nicer than I2C in so many regards: <i>much</i> longer range, masterless (any node can talk directly to any other node), packet prioritization built-in, deliberately designed to be more or less impossible to wedge, possible to do IC-to-IC on a board without transceivers by using a shared open-drain bus (like I2C, but with only one wire!)... and plenty more.<p>Really the only downside to CAN is that the spec requires timing that's tight enough that everything has to have a crystal on board. Ah, to have an alternate reality where CAN's timing requirements were relaxed enough for that not to be a requirement and it had caught on as the IC-to-IC interconnect standard instead of I2C...</p>

<p>They didn't say that HN is turning into Reddit, they said that the conversation quality has gone to shit.<p>I don't agree with that statement universally, but I have to say I do when it comes to this article. I came here hoping for substantive discussion from those who'd had a chance to try it out; instead what I got was a seemingly endless stream of venting. There's a place for venting - and plenty to vent about with the state of AI nowadays - but to borrow from the HN guidelines you linked, it does very little to gratify my personal intellectual curiosity.</p>

<p>Fun story: I used to own a Prius, and it turns out they expose the speeds and torque values of MG1, MG2, and the engine independently on the OBDII port.<p>What this means it that you can set up an app like Torque[0] and add widgets that show you how fast each of the motors are spinning, live, and watch what happens when e.g. the engine starts: MG1 and MG2 both torque the engine forward, MG2 just enough to stop the car from attempting to roll backward in response to MG1's torque through the planetary gearset, and then MG1 spins up with the engine and then stops torquing it once the engine reaches idle.<p>Battery charging while idling is similar: MG1 turns itself into a generator, fighting the engine and generating electricity in the process. The throttle opens considerably, as if you'd pressed the accelerator halfway to the floor, but MG1 and the engine work together to keep the engine's RPM around ~1,200 so you'd never know it - it's as if you're driving up a really steep hill that stops you from accelerating even though you have the gas pressed halfway down. And then MG2 torques <i>backward</i> to stop the car from rolling forward any more than the Prius's normal "simulate a normal gas car's tendency to roll forward when the user lets their foot off the brake" would have it do.<p>It was fascinating to watch, and I kind of regret not building an app similar to the parent comment's link that showed what my car was doing in real time with the gears drawn out like that.<p>[0]: <a href="https://torque-bhp.com/" rel="nofollow">https://torque-bhp.com/</a></p>
