We just created a custom dashboard project in LV. How do we get our new custom dashboard to automatically show up in the Driver log in?
You used the magic word “replace” in your question. The answer is to do just that – replace the existing Dashboard.exe file with the one you created. It’s in the Program Files (x86)\FRC Dashboard directory. You might want to rename the original Dashboard to something else instead of just replacing it.
From here you can download a document that gives a lot of information on the custom dashboard. Towards the very end, on page 14 of 15, it explains how to set the custom dashboard.
