Page 10, Q27. What do you think about the software that comes with a microcontroller development board(examples, libraries, compilers, RTOSes, etc...)?

1 Bundled software does not integrate well with RTOS, often has many bugs.Not to be trusted. Used only as a general idea as to what to do.

Feb 20, 2012 8:05 AM

2 boh?? Jan 18, 2012 5:08 AM

3 it is a demo which saves time, software which is "know-to-work", not onlysoftware author's but also board author thinks the software is worthy

Dec 14, 2011 9:23 AM

2 Well structured; very effective and appropriate questions. Jan 8, 2012 3:18 AM

3 Supply as many demo applications as you can using differentmicrocontroller's peripherals. This way, it is easy to evaluate your tool.

Dec 27, 2011 11:28 AM

4 all in this survey was perfect question. smart... i need see conclution aboutthis survey. Nice survey

Dec 21, 2011 7:09 AM

5 ya.its good to analysis & to know more about the future requirement Dec 16, 2011 12:09 PM

6 Not good Dec 15, 2011 2:30 AM

7 Sometimes I would have liked to tick "not applicable" as the item was "notapplicable". Unfortunately this option was not present.

Dec 13, 2011 10:13 PM

8 Once you start using the tool in your project. It won't be easy to switch tooleven the tool is not very good. So I think provide the IDE/SDK + Demo boardto user is a good strategy.
