(D.Adams)If you really want to do this, there is set_jmp() and jmp(). Stack Exchange network consists of 177 Q&A communities including Code: [Select] int TestArray[10]={0,0,0,0,0,0,0,0,0,0}; This makes you code easier to read and easier to fix.If this answer wasn't what you meant then feel free to comment and I'll see if I can come up with a better answer.Thanks for contributing an answer to Arduino Stack Exchange! Void means that the function does not return information. Arduino Stack Exchange works best with JavaScript enabled The header file consists of a descriptive comment, constructs (the one with #ifndef Blink_h and #define Blink_h), needed include files (#include ), constant definitions (#define ON true, etc.) The Arduino programming language Reference, organized into Functions, Variable and Constant, and Structure keywords.

Discuss the workings and policies of this site It would have been easy in FORTRAN to use the Go To, but in C I see it is discouraged, plus apparently in C goto only jumps to a subsequent statement, not a previous section.Put the code you want to be able to call again in a function. These interrupts can be set to trigger on the event of RISING or FALLING or LOW levels. return - Arduino-Referenz Diese Seite ist auch in … Start here for a quick overview of the site So you don't go back to setup(), you call the function.

Il you return from within your loop function, it will be called again.To expand on what jfpoilpret said setup() and loop() are called by the code you can't see in every program. Some functions do return values – our DogWash function might return the number of buckets it required to clean the dog.

In the case of loop() this will cause it … Ah, this is obviously some strange usage of the word 'safe' that I wasn't previously aware of. Now we will see how to use interrupts in Arduino Board.

• Perform a set of actions – control pin values – print information to screen I want to test a condition that is running in void loop() and if that condition is not met, I want to jump back to void setup() where things happen just once, do it's thing and drop back into void loop() again, etc. You will save everyone's time if you read and follow the forum guidelines. Return Type Function • Takes in Parameters (Most of the time) ... • Void functions do not return a value.
Setup() as a general programming ethics must be used only to set your working environment and any need to reset at runtime seems illogical.The thing to clarify is why the OP wants to call setup()? It has two types of interrupts: External Interrupt; Pin Change Interrupt External Interrupt: These interrupt are interpreted by hardware and are very fast. Anybody can ask a question Featured on Meta Anybody can answer The function analogRead() returns an integer value between 0-1023. Call it from wherever you want in loop. To call you code while a condition is met you could either wrap it in a loop or an if, within the and then call this function from inside the if statement.

So, a function that has a return (and the necessary parameters to allow it to return something after having been called) is the ‘servant’ of the main loop but non-return (I.e., ‘void’ ) functions do not directly serve the main loop. Does she/he expects a full reset (where all things start fresh again, stack, heap, relevant global variables set to 0, etc) which setup() then will NOT do, or just to benefit from some already written initialization code (at the risk of calling twice and wrongly some xxx.begin() and other class initializer that we usually have in setup() too)Hello - Please do not PM me for help,  others will benefit as well if you post your question publicly on the forums.Please post technical questions on the forum, not by personal message. println ("-----"); } The code above that creates the function is called the function definition.

Of course you could mean you want to restart loop() halfway through the code in loop, in which case you should use the return; statement, which will cause the current function call to exit immediately and return control to the calling function.
