Control LED Strip functions using SINGLE Push Button Help!

dsdelavega · June 21, 2020, 8:08pm

Hello, I am attempting to modify my code, which currently has two functions that I use:
RunningLightsAll() and FadeInOutAll(). I am trying to have the button alternate between the two. I don't want to hold the button down for some time but rather have a simple push of the button change the current function that is running. I currently have the button being "read" during the While loops of the function to change between the two. However, this only works if timed correctly(@ location in code). I need help to change between the two. Any guidance or tools in the right direction are greatly appreciated.

Read Adafruit’s multitasking discussions 1, 2 and 3.

BTW

Use code tags.

Use CTRL T to format your code.
Attach your ‘complete’ sketch between code tags, use the </> icon in the posting menu.
[code]Paste your sketch here[/code]

dsdelavega · June 22, 2020, 7:30pm

Thank you larryd , it seems i have quite a bit of reading to do. Will get back if any issues occur.
Also, thank you for the info on posting code. I thought i did CTRL T but I will recheck the next time I post ANY code.
Also, by 'complete' sketch, do you mean the code that I am having problems with/have questions about? And not the actual complete sketch?

LarryD · June 22, 2020, 7:34pm

We ask that when large sketches have a problem, you reduced it in size to the point where the problem still is seen.

Hello again everyone. Question, I am attempting to set up a button with 3 functions. OFF/ALL/PHASE. off and all are pretty self explanatory. For phase, I want the phase code to run forever until the button is pressed again. My issue arises with the fact that I don't know how to keep the "phase" code running without inserting a while(1) loop, which results in it being stuck forever in that state unless i restart the program. Should I use a timer interrupt for this or is there a better way to write my code for the PHASE.

void Phase(uint8_t interval) {
      ActivePattern = PHASE;
      Interval = interval;

      float r, g, b;

      /*********** PART 1 ************/

        b = (k / 256.0) * 0x00;

Also, by 'complete' sketch, do you mean the code that I am having problems with/have questions about? And not the actual complete sketch?

No all the sketch is needed. It is surprising how often the mistake is not in the place where the problems manifest themselves.

My issue arises with the fact that I don't know how to keep the "phase" code running without inserting a while(1) loop,

Simple you don’t have a while statement at all. Did you read those links?

You need to implement your code as a state machine, that is each animation function must do a small bit of the function and then return. So no while statements and no for loops, with show or delay in them and no delays at all.

If I give you some links will you read them?
