I wrote a ton, but I hope that lets you in on the "secret"  |
Switches on the DS side can still be read and used to select Autonomous modes. The difference is that they now cannot be read in Autonomous/Enabled mode. Read them in Autonomous/Disabled and cache the values for use during Autonomous/Enabled. Also, there are reports that the values return incorrectly from the last cycle of Autonomous Disables, so make sure your code has a way of dealing with this. |
Our team did some experimenting and found that at least in LabView, the last time Auto Disabled runs the DS input values are in fact zeroed out just like they are if you try to read them during Auto Enabled. I assume the C++ handling is similar but we have not checked that.
It's hard to handle this in the LabView Basic Framework, but is pretty straightforward in the Advanced Framework - attached is an example Disabled.vi for the advanced framework that shows this, hope it's useful! The AutonMode.vi also attached is just a simple "functional global" variable. Autonomous Independent just reads the cached value.
