Hello erik,

As per the attchment that i had sent has the same concept as variables declared as votaile bool. But even after the declaration as volatile bool i got to see no improvement in the code. Jua go though the attachment and please let me know the actual problem. Thank you.

Your code is huge. And it is a bit confusing that your code does not correspond apparently to what you posted here.

My advice: Make a simple test case and see if it works. If yes, then the problem is probably not the tickers but something in your code. I was planning to see if I could figure it out for you, but setting the ticker was called by a function, which in turn was called by another function, which again was a generic switch statement (tbh there seem to be more switch statements than really needed).

Then add that the single file we are talking about already has more than 2000 lines of code. So really: Simplify your problem and we can help if you still got it. But I am not going to debug 2000 lines of code, without even having the setup to run it.

Or to put it another way: Rather than wasting peoples time do what I suggested last time you asked this question rather than reposting the exact same question a second time and getting the same answer from a second person.

Hello Erik,

I had made it simple way for you to understand how i am calling a function.

#include "mbed.h"

Ticker 1
Ticker 2
Ticker 3
Ticker 4

void Function()
{
	if(flag1)
	{
		do some work for flag 1();
	}
	that contnious for flag 2,3 and 4 as i am using 4 tickers
}

//passing time duration for the tickers

void function time (volatile uint8_t sampling rate)
{
	function.attach(this,&attached function,sampling rate); // function dynamically changes the value of sampling rate attched to ticker time
}


void attached function()
{
	flag 1 = 1;
}

The problem i am facing is that I am able to get an interrupt for only 2 tickers.but there is no interrupt generated from other 2.

But i am able generate interrupt for all the 4 tickers if i do in this method by calling initialize function before main.

#include "mbed.h"
void init()
{
	function.attach(this,&attached function,1); // Ticker1
	function.attach(this,&attached function,2); // Ticker2
}
void main()
{
	
}

if i do this way i am able to get interrupt generated. I have no idea what would be the reason for this kind of strange behavior it makes no sense for me if i would like to change time value dynamically from the user input. As per Andy suggestion i had removed unnecessary code and made to 39Kb size but there was no improvement. can any one know how to pass the time value dynamically from the user input. Sorry andy but unfortunately i had clicked the option assign so i felt other people suggestions are also more important for me thats the only reason why i have to repost.

The init function is still called from main this way, so executed within main. But can you just make a simple example where you for example flash some LEDs, or print some messages to your PC, which demonstrates the problem.

Hello Thanks for your suggestion and i had achieved by using inline function. So that code has become more faster than before and was able to access the timers too. Thanky Erik and Andy.
