Is S/X right for me?

·· I was just looking through my parallax catalog the other day and noticed that the S/X micro controller might work for a project I had in mind.· But before I buy a kit I want to find out more about it.· my questions:

1.· Do you have to have a development board to use it or can you attach your circuit·directly to it?

2.· Do you have to have a development board for·debugging programs?

3.··If yes to number 2: can you debug a program on the board and then move the chip from the board to a custom circuit? will it·run the program the same?

4.· The project I am planning on doing·involves infarad communication, will the·IR·receiver/transmitter·circiut used on the BOE-Bot work with the S/X?

    1. You can program and debug it while it's in the circuit.
    2. No (see #1)
    3. See #1
    4. Yes.

    The main thing to watch out for if you are going to be debugging is you clock source. When debugging your circuit the clock has to be generated by the SX-Key. If you use the internal R/C circuit then no worries. If you have a resonator you can program with the resonator in place but have to remove the resonator for debugging. If you use an oscillator then that needs to be pulled out for both programming and debugging. So, if you are going to be debugging your circuit just make sure your clock source is socketed. Also, pickup a couple of the $9.95 protoboards as those are useful for projects and already have all the sockets for a variety for clock options.

    Besides that just have a 4-pin header near the chip which has the osc pins, +5v, and gnd

    The SX-28 comes in a DIP package that is easy to adapt to DIY. In fact, so does the Propeller. Parallax has wisely understood that hobbyist and small developers prefer to use DIPs as SMDs often require making your own boards. While making boards isn't hard, it is not needed for tutorial study.

    Also, Proto boards allow you to easily jump into programing tutorials without building a lot of gagetry
