  1. Post Which microcontroller is best in terms of price and performance?

    I"m a bit of a noob to robotics, but have dabbled in elctronics a lot. I justed wanted to know which microcontroller is best for robotics in temrs of price and performance. A few people have told me Pic are the best, but I'm not quiet sure if it is the best. Thanx, DannyDeth.

    Re: Which microcontroller is best in terms of price and performance?

    "best" is mostly opinion. PIC/AVR/MSP/etc are very closely matched for speed/price. I think more important for hobby and education use is the ease of use and support community -- and in that respect, the Arduino (built around the AVR) wins pretty much hands down.

    Re: Which microcontroller is best in terms of price and performance?

    I agree with Fergs, in terms of price/performance there is no major "value" difference between the major vendors. You might get a different answer on Microchip forum or AVRfreaks !

    It depends on your robot and the actual performance you need from one or multiple microcontrollers. I tend to use PIC 8 bit for really small low cost stuff in assembler, AVR 8 bit/Arduino for medium stuff in C, top end is ARM, AVR32, PIC32 in C. I do weird stuff on propeller or FPGA(Microblaze). They are own my choice and my comfort zone.

    While chip price and performance are chip choice vectors, you must also consider the cost and productivity of your development environment. Development tools include software development environment, and also hardware programming and debug tools, and may be free or not !. And as Fergs says, the availability of free support on the forums is very important, chosing the latest blazing chip may not yield the best knowledge base for support.

    Thanx a lot, im gonna go search for that at my local electronics store ASAP.

    Or better yet, just order an Arduino online. I doubt your local electronics store will have them.

    You really can't buy most of this stuff locally -- about the only "micro" you'll find locally is a Basic Stamp at Radio Shack -- and that's really not much of a microcontroller.

    Does anyone have any idea of a site i could order an Arduino from?

    In terms of price, probably the picaxe series, at 4$ a chip it is hard to beat.
    Results were inconclusive, the darn thing blew up!

    It is?
