Robotc tasks code#

Again, if you start above the first line of code that looks wrongly indented you should be able to track down your error.

You can see in the above code listing that task main() and its body are indented (pushed to the right). Unreferenced function / Undefined ProcedureДЇrom the following code: void movForward ( float inches ) In a perfect world you should strive to have no messages at all in the Compiler Errors window pane, your code will generally be cleaner.

Error something is broken and you need to fix it.

The compiler is pretty sure you wanted to use it, but youвЂ™re not. The observation (d) is a combined image from the downsampled output of the four RGB.

Warning the compiler is pretty sure this thing will cause a problem, just maybe not right now.

Maybe you defined a variable to use somewhere else, but deleted that other code, so that variable is hanging around for no reason. These messages are really just to help you keep your code clean, as far as the compiler can tell they donвЂ™t have the potential to cause any problems.

Info nice to know information that the compiler discovered.

LetвЂ™s quickly chat about the various Message Types:

What type of message this is (Error, Warning, Info).

What line number the compiler is talking about.

Looking at the above screenshot thereвЂ™s actually a lot of information there: First letвЂ™s look at where you can find your compiler messages:Д¬ompiler Messages show up in a window pane at the bottom of the ROBOTC IDE. Sometimes the messages you get back from the compiler arenвЂ™t completely obvious, but the more familiar you get with them the easier itвЂ™ll be to figure out whatвЂ™s wrong with your program. HereвЂ™s the sign that you did something wrong: Compiler ErrorsД¬ompiler Errors will, unfortunately, be a fact of life as a programmer. Once youвЂ™ve found it, then look at the details for that section and most importantly the FIX listed in each section.

Scan through the headings (theyвЂ™re underlined) and see if you can match up a few of the words.

Task 1 was again interrupted when another time slice had completed and, as task 3 was now wanting to run, the scheduler allowed that to happen.

Press CTRL+F and type a word or two in that box to search (use the most unique word in the compiler message) The ROBOTC scheduler allowed task 2 to run after the time slice for task 1 was completed, execution then returned back to task 1 as there were no other tasks waiting to run at that point.

Two ways to find what youвЂ™re looking for (Starting from the first compiler message): I include here text from the aweseome jpearman about how RobotCвЂ™s tasks work, because I couldnвЂ™t possibly say it better myself.In order to make you more self sufficient, and to save my sanity :), here are a list of things I expect you to check before you ask me or your teammates for help. Technically, RobotC canвЂ™t either, but it has the ability to make it seem like itвЂ™s multitasking using things called вЂ¦ wait for it вЂ¦ tasks. The main or primary task is automatically started when. ItвЂ™s helpful to give the function a name that reflects the behavior it will perform. ROBOTC Tasks Up to twenty tasks (19 user, 1 main) can execute concurrently within a user program.
