Analog push Button: Need advise to find a good library

Projects Programming

Hello

I want to get push switch status from an analog read. I tried many library, but did not succeed to get data for a long press,

At the moment, I'm able to read the analog value for 4 switchs, and get witch key as been pressed. Now,
I want to properly debounce it, get if the switch is a click or a long press.

I tried, these library: with no success: Multibutton, Multibuttons, ButtonFever. end few others

Any input appreciated

Have you got multiple buttons with different associated resistors attached to the same analogue pin ?

Hello UKHeliBob
Yes, I got the resistor voltage divider. I read the proper value for each key on one analog pin.. My problem is with debouncing the read and get if it is a click or a long press.

Hello arjfca

We need some additional information.

Post your sketch, well formated, with well-tempered comments and in so called code tags "< code >" and a detailed circuit diagram to see how we can help.

Have a nice day and enjoy coding in C++.

A part of the problem is resolved. The read is debouced using a timer. The proper key pressed is decoded.

Now, where to add a timer for a long press after debouncing?

#include <Every.h>
Every debounce(50,true); //debounce timer  True on first instance
Every::Timer LongPress(1000);  // Valid if a switch is pressed for 1 second

void ReadSwitchButton(){  // Read button switch
  //up button 1024
  //down  293
  //Left  82
  //Right 30
  //No_SW  12

 
  unsigned int value = analogRead(ANALOG_PIN);
  if (value <=NO_SW) {
    SW=0;
    return;
  }
  if ( debounce() ){
    if ((value >= (SW1 - SW1_MIN)) && (SW1 <= (SW1 + SW1_SUP))){
      SW =1;
      
      }
    else if ((value >= (SW2 - SW2_MIN)) && (SW2 <= (SW2 + SW2_SUP))){
       SW =2;
       }
    else if ((value >= (SW3 - SW3_MIN)) && (SW3 <= (SW3 + SW3_SUP))){
       SW =3;
       }
    else if ((value >= (SW4 - SW4_MIN)) && (SW4 <= (SW4 + SW4_SUP))){
       SW =4;
       }
  }
 
}
