doimant/button_sl

Button is a class for (debouncing) button queries. The included ButtonSL is extended so that a distinction can be made between a short and long button press.

Library doesn't compile...

Hi,

unfortunately I couldn't get the library compiled in Arduino IDE 1.8.19 on a Wemos D1 mini (ESP8266) with my code.

First error I got was:

'Button' does not name a type
respectively
'ButtonSL' does not name a type.

I don't know why, but neither the classes nor the enums are recognized (library is installed and included correctly, I can see in the compiler output, that it is recognized as an include).

BTW: keyword contains an error ("ButtonLS" instead of "ButtonSL" as keyword)...

First read of button with .tick() doesn't seem to work...

Hi,
I have an application where I use two buttons in the startup phase to initialize an EEPROM.

So I declared the buttons with:

// Buttons
using namespace Btn;

Button   btnAntUp{DI_ANTUP, LOW};        // AntUp button with pull-up, active low
Button   btnAntDn{DI_ANTDN, LOW};        // AntDn button with pull-up, active low

(where DI_ANTUP is 12 and DI_ANTDN is 13 on my Wemos D1 mini).

After initializing in setup() with

btnAntUp.begin();
btnAntDn.begin();

I tried to initialize the EEPROM when both buttons are pressed at the same time:

if ( btnAntUp.tick() && btnAntDn.tick() )
{
   // Initialize EEPROM here
}

Unfortunately the first read of the buttons alway seems to return 0, so I never get the EEPROM to be initialized when both buttons were pressed at startup.

A workaround for me was to do a dummy read after the init:

btnAntUp.begin();  btnAntUp.tick();
btnAntDn.begin();  btnAntDn.tick();

After this dummy read, the if condition is true if both buttons are pressed and the code between the braces is executed as expected.

I assume, that this isn't the expected behaviour of the .tick() method, isn't it?
