#174547 - I've looked at a lot of "eval" boards ... Responding to: ???'s previous message |

It seems to me that there are (at least) three different goals that different people might have in mind for demo/eval/development kits/boards
Please note that I'm using the terms purely for the sake of argument - I am not intending to assign any specific meanings here. Demonstration The board is really just to show-off, "look! it can do this!" In this case, it doesn't matter (much) about source code or hardware access - you're just supposed to see it doing the demo and say, "so it can!" The demos I've typically seen are the sort you can do for yourself in about half an hour. In the event you can't, the included materials won't be of any use at all to let you do that. Evaluation
The board gives you a bunch of common/"useful" peripherals to "play with" in order to get a "feel" for the device. Source code here should meet the full exemplary standards, but the hardware is intended to be self-contained rather than for adding your own. Development This is to get you started on a real design; ie, to do some real development on. Again, software should be high-quality, and there should also be easy access for adding your own hardware It's been decades since I last saw an EVK of any sort, even fairly costly <<$1k ones far to complex to be of any real use, that would do that. As I've noted in past comments, the "demo" stuff, when not so simple your 12-year old could do it, seldom works as it should. I'm not impressed by a $40 chip that can blink a LED at one and only one frequency. RE |
