Okay, I decided to just go for it and get the blitz at 50% off.· I aso ordered the SX 28 dip and a 50mhz resonator.· What is the basic setup to program the SX?

Thanks.

    The easiest way to start is to also pickup one of the SX28 or SX48 protoboards since they already have the programming header installed. You can still work with just the SX28 on a breadboard. You'll just need to wire up a 4-pin header for programming. A good reference is the schematic that Parallax has on the SX28 protoboard page and also the datasheet they have posted for the SX28 itself. One thing to bear in mind is that the pinout for the Surface mount and DIP versions of teh SX28 are slightly different so double check your wiring!

    Beyond that just install the SX development software and try some of the examples in the SX/B help file. It will help jump start your projects.

    You might want to also get some 4 and 20 MHz resonators. You gennerally want to run your SX program at the slower speeds for stability reasons and only go to 50 MHz if your application is just too slow. 20 MHz works great for most of my applications. I have only had to use a 50 MHz resonator a couple of times where I used alot of processing power for a dual LED matrix display (e.g. 128 x 32 bi-color).

    I can second that! I supply a 20Mhz resonator with my SX48 module kit and it works well for most projects I have done. The stability may be a factor when running on a breadboard as well. One of the other reasons that a 4Mhz or 20Mhz is often a good choice is that it uses a bit less power.

    Well, I have a 4mhz resonator as well. I may get a sample order of a 20mhz resonator... smile.gif

    Also, I will probably make my own version of the tech board. I have all the parts. (or I will once my order ships)

    Also, I think I will learn assembly for the SX. It seems to be a nice way to learn ASM... Is there some link to an ASM tutorial I can look at while I wait for the Blitz to ship?

    Thanks.
