Menu EXIT

[manaioussema]

Hello first i would thank you for this great library. i have a question about main menu EXIT, what happen when the main menu exit ? where goes the code ? and thanks.

Hi! Thanks for using the library :D

if you do not specify nothing, an internal dummy function is used

you can point your own function to be used instead, by changing your navRoot object idleTask member to point to it.

nav.idleTask=myFunct;//can do this on setup or when appropriate

you can force menu to a sleep state by doing:

nav.sleeOn(myFunct);//next poll will be redirect to myFunct <-- my error

nav.idleOn(myFunct);//next poll will be redirect to myFunct

if used on setup then the menu will 'start' on suspended state (click/select to leave)

myFunct is of type idleFunct, that is:

result (*idleFunc)(menuOut& o,idleEvent);

your function will be called for each of your output devices (passed it at first parameter) and with the following events:

enum idleEvent {idleStart,idling,idleEnd};

so, it will be called at least 3 times, on entry with idleStart, on poolpoll with idling, on exit with idleEnd

on some devices (like serial) the poolpoll=>idling is only called once, on others (requiring redraw) it will be called for each poll.

if I misspelled something or if something is not working please let me know.

i have tried what you said but i didn't get what i wanted. In fact, what i want to do is to make a monitor screen that displays some informations (that are updated like time) when i'm not using the menu and when i need it it shows back, i have also read the other issues and the different ideas to do this purpose but the idle state seemed to be a good solution. If you have other idea, i would be thankful to hear from you. Best regards.

on the above answer i've already spotted some errors and there might be others (edited the answer), because I was away from my computer and rushing when I wrote that. Sorry for the inconvenience.

The idle function is not good for updatable info on serial monitor. For that I would use something like:

void loop() {
  nav.poll();
  if (nav.sleepTask) {
    //do your update here...
  }
}

info using the idle function will only be called 3 times (entry,idle,function) on some devices (like serial monitor). however its possible, by signaling dirty on the device...

hope it helps :D

P.S. there is also the wiki as a good source of info in case you have not tried it yet:

thanks for your replies, i already tried to set a variable in my idle function and then test it in the loop to be able to make the update but the if (nav.sleepTask) is better and cleaner. Another little problem i'm facing is the encoder glitching, what i'm mean is when i'm turning it the selection jumps many items upward and downward with a strange behavior , i've tried to change the sensitivity and steps but with no good results (i'm using the clickEncoderIn.h). And for Nokia 5110 LCD the text doesn't fill all the screen .Thank you again

[neu-rah]

there is also encoderIn.h clickEncoderIn has accel. while encoderIn has not, don't know if its related. Also encoderIn will require a call to begin in setup to initialize the pins and an extra library PCINT https://github.com/neu-rah/PCINT. encoderIn uses pin change interrupts. Similar issues might also be caused by bouncing. you can debounce the encoder with small capacitors between the encoder pins. you're welcome :D

P.S. if this persists please open a new issue encoder related, it makes life easier for future users reference.

[neu-rah]

solved?

[manaioussema]

yes by changing the encoder and i'm tweaking the sensitivity parameter. Thank you.
