Yes, that's right i don't clear the settings when you change the ledwiz number. That's the behavior i wanted.
As the user interface is still "raw" , you can easily change the ledwiz number without having saved your settings for the previous ledWiz. So, if i clear the field... and you realise you forget to save... you will have to set up all again...
So to avoid that, i let the current settings and you have to change.
Of course, i will enhance the tool in future version. For now it is a first version and i tried to cover all LedWiz features the fastest and the best i could. (FYI , I spent only 16 hours for the LedWiz support in AtomicFE (including : writting my Dll, configuration tools , and added the support in Atomic core) . The LEDWiz is a very nice piece of hardware , very easy to drive!
Gonzobrian wrote a very good "How to" guide for Ledwiz and AtomicFE , you can find it in the Docs folder of Atomic Distribution. And for one time, the doc is in Real English!!! (not in my French-English!!!
Concerning the Dll, i will release a Dll for other developper soon. I will post on the forum.
