Circuit Design and Component Selection for MSP430's

Jonthornham
Expert 1490 points

Please excuse my ignorance in the area.  I am a mechanical engineer by trade and have spent the last while learning about hardware and MCU's.  I am making progress but find that I am puzzled with component selection and circuit design.  For example if I am using a CR 2032 to power a design what would be the ideal resistors, capacitors etc to use? Is there an ideal current to run a design at with a 2032?  When do I need more voltage or current?

I know that each design is on a case by case basis and that reading the data sheet of the components is critical.  I am however looking for a good book that covers the topic in detail.  Like anything I know there is someone out there with much experience then I have who could teach me a lot.  I know there are general rules I could learn.   I've been looking at the "Circuit Designer's Companion" by Peter Wilson and was wondering id anyone had any other suggestions.  I am also open to website, etc that have good info.  Any help would be greatly appreciated.

Take care,

Jon

    There's two extreme ways to learn (fishing): 1) sit in the library until you know everything about subject, know how to catch ANY fish you want. 2) just go fishing and see what you can catch. It's always good to know at the very beginning - what kind of fish you want to catch because they are so many.

    I am not sure what I want to catch.  Maybe I didn't explain things well but I am looking for general knowledge on circuit design and layout.  Much like fishing, sometimes it best to survey the waters before you throw on any random fly in hopes to catch something.  I am not looking to learn the genetic make up of the fish before I start fishing but I believes it's wise to have a general understanding of the fish population.  That's the book I am looking for on circuit design.  I want a general understanding I can expand upon.

    IF you ask "give me ideal components for CR2032 designs" I will answer: take a look at Mouser or Arrows electronics components inventory - every component here will be ideal in some way for some design where CR2032 is one of the power supplies. - Overly broad questions usually don't result in usable answers.

    You need "starting point". Like - project named  "LED flasher" running on RC2032. Then we can talk about ideal LED, ideal resistor, ideal current for LED and so on.

    Check amateur uC designs (there's lot of them exposed in the web), see what you like, select easiest design to implement, then come here and fill the gaps in your knowledge about building particular circuit.
