Password Card

Pro Feature

This is an exclusive feature of DASH Pro. Check it out here.

Just like Text Input card, Password card gives you the ability to take String input from user in a inconspicuous way and save them in your application.

This card is very useful for saving any kind of secret or password that requires the input value to be not visible on dashboard in plain text.

Initializer

/* 
  Password Card
  Valid Arguments: (ESPDash dashboard, Card Type, const char* name)
*/
Card card1(&dashboard, PASSWORD_CARD, "Test Pass");

Callback

Password card requires a callback function which will be called when we receive a input from our dashboard. In setup block, we will be calling our attachCallback function and provide a lambda (callback) function with a const char* (character array) argument.

/*
  We provide our attachCallback with a lambda function to handle incomming data
*/
card1.attachCallback([&](const char* value){
  Serial.println("[Card1] Password Card Callback: "+String(value));
});

Updater

note

Password card doesn't require any updater as value is not passed back to dashboard.
