Hello, we are currently working on vision tracking for our robot using Wind River C++. We were attempting to use messages as debugs and realized that we are not receiving updates in the ‘User Messages’ section of the Driver Station.
This is the code being used to send and update messages to the Driver Station:
The user message will sometimes print once when the code is first deployed, but will not continue to update after that. We have tried running this command at various points throughout the program without success.
I haven’t used the LCD yet, but it works by sending a big block of text that sets every character on the display. You don’t want to include newlines (even if the LCD hardware handles them, it would mess up the position of the other text being displayed).
Your code will write “Message” on line 1 starting at column 1. If you run it again it will do the same thing. Maybe try something like this to see if it’s updating:
