Compile errors and warnings can occur when you’re creating your LEGO Mindstorm programs. Fortunately, Mindstorms is able to prevent you from most compile errors that you could make and any errors that do occur are clearly marked. This video will demonstrate some common errors that you may come across and how to address them.
- [Voiceover] In programming there are generally…two types of errors or warnings you can run into,…compile errors and runtime errors.…Compile errors are problems…that prevent a program from running…because it doesn't follow the syntax…or semantics of the programming language.…In text-based programming misspelling a function name,…forgetting a semicolon or using an improper data type…will cause a compile error.…When one of these things happen…the program doesn't understand what to do…so it can't run.…You can think of these errors like…when someone asks you a question…in a different language.…
If you're not familiar with the language…you're unable to understand them…so you can't answer the question.…In text-based programming languages like C or Java…you might not realize you have syntax errors in your code…until you try to compile and run your program.…When that happens you'll get a message…or set of messages stating why it can't execute.…In graphical programming you can run…into similar compile errors.…Here I've opened project 08_01_Error_Start.…
Learn how to unpack the hardware, connect to the programming interface, run prebuilt programs, and control the motors and sensors. Chapter 6, "Adding Flow to a Program," covers advanced programming topics such as transferring data between blocks, using variables to store temporary data, programming conditional logic, and looping actions to run again and again. By the end of the course, you'll have the skills to bring your own robotic creations to life.
