We are using Pros for v5 for the first time (switched from Vex Coding Studio a few weeks ago), and got most of our user control working (tank drive, lift), however we are having trouble with the Buttons. We are using the getDigital() function which works just fine on our lift and Hdrive wheel, (which are controlled by R1, R2, L1, L2).
However, when coded the same way, the getDigital() does not work with UP, DOWN, A, B. We are sure it is a code issue, since switching ports shows us that each of our components works with the R1,R2, L1, L2 buttons.
See screenshot for our code that is not working (Buttons A and B).
Here is a screenshot of working code:
Here is a screenshot of the configuration and drive control.
Remove E_CONTROLLER_ from in front of DIGITAL_A and DIGITAL_B.
In other words, your condition in the if statement should be:
master.get_digital(DIGITAL_A)
E_CONTROLLER is the prefix for choosing controllers, not buttons.
We tried that as well, and it did not work.
master.get_digital(DIGITAL_A)
No, @Loan_Wulf is incorrect.
E_CONTROLLER_DIGITAL_A is just the good programming practice, long form of DIGITAL_A .
If you have enabled the short name syntax in your main.h, you can use either.
If it compiles, you should be fine.

As for your issue, I’m not sure what it is.
There should be no reason why UP does not work but R1 works.
The only thing I can suggest is isolate the issue, comment out everything except the lines in question.
Make sure the motors are properly configured, and that you are not setting 0 to the motors somewhere else.
Try switching the lift control to UP and DOWN, to see if the problem is related to the controller, or if its related to your tilter motor configuration or port.

Sorry, I’ve only been using PROS for about a month (I’m a long time Java user). @theol0403 is the expert here. But yeah, I would guess something is wrong with your bot (incorrect ports, etc.) or with your motor variables. As @theol0403 pointed out, this could also occur if you set the motor speed somewhere else that writes over it. That’s definitely one to try out.

Can you post the whole section of code? Not just the small snippet?
