Galileo should not piggy back arduino pins. Why?Why should they come up with a pin layout that specifically isn't compatible with arduino just because? That seems like a ridiculous requirement, but if that's what you want I guess you're out of luck. Yeah, it's more expensive than an ARM, currently hovering around $50 for a spec sheet that's a bit behind the times (but my position was that the current crop of boards is really disrupting on price).
People didn't buy the first generation pi for performance. Also, the geode came out in '99, so I'd kinda expect new products to be faster. SMBus was on the support chip in the geode model. I guess you can complain that they weren't on the same chip, but things have gotten a lot more integrated than they were 15 years ago so it seems like an anachronistic complaint.
For some applications yes, for some applications no. We're seeing libraries written in high level languages on all the platforms, and apps which can tolerate that aren't pushing the limits. (That's true of most of the hobbyist level projects which are driving the sales numbers.) There's no technical reason why a trivial library that (for example) reads a couple of values and does a little math before returning a result has to be tied to a platform, but that's the way things are right now and that creates a barrier to switching platforms that benefits the platform providers more than consumers.
Intel should define something different. Ex. Pi.
All clones always piggyback pi or arduino. What?..
Without piggy back. Intel will has their on market. Looks on pi.
Galileo has limited support too. They try to tight with arduino.
Sure. Evolve.. Arm has PCI ex included in the higher licensing model. But pricey and costly compared win current x86.
Smbus is not common. I2c and spi is common due on simplicity.
I am not complaining. Just to explain my experience.
Back to cost. Microcontroller is cheap.
Microcontroller is fast on Input output response.
I prefer speed. Small footprint and low power. Nothing can beat microcontroller.
I put general link on differences. Nothing black or white.
l wold like to put basic understanding correctly.
As I said all goes back to cost, small footprint, and low power.this is the big plus in mcrocontrller.
