[GrandFather]: It's a good day end here Corion. The start was somewhat less than average!
[Corion]: GrandFather: All's well that ends well? ;)
[GrandFather]: I'm fighting with a third party device our software is to support. The documentation for the device's SDK is quite a lot less than average and most of today was spent ...
[GrandFather]: discovering that one of the sensors for the device lies about the gain range it is using!
[GrandFather]: However, by the end of the day I had discovered its deceptions and now have it working correctly, so yes, all's well that ends well. :-D
[Corion]: GrandFather: Ah, (hardware) APIs - I have a similar situation with Chrome and its API... It is fairly underdocumented and I guess I have to hunt...
[Corion]: ... down supposedly working code to find out what I'm supposed to do
[GrandFather]: I haven't any "working code" to inspect! I have to find ways to generate reference signals then check the numbers I get at the far end match.
