How to configure a relay with turn-high-low via GPIO?

[Yonsm]

Hi Xoseperez, I want to configure a relay that represents a high-low voltage at GPIO for both turn on/off action, that means I need toggle GPIO pin to high and then turn GPIO pin to low (about 0.3s delay) for both turn-on and turn-off action.

I found type(RELAY_TYPE_LATCHED)/delay_on/delay_off/pulse/pulse_ms params maybe is the right way, but I did not find relay config UI on web frontend. How can I get there, or how can config the relay on hardware.h.

Thank you and your help will be highly appreciated:)

I found that! The following configuration could be worked well:

    #define RELAY1_PIN          14
    #define RELAY1_RESET_PIN    14
    #define RELAY1_TYPE         RELAY_TYPE_LATCHED
    #define RELAY_LATCHING_PULSE 200

But the best code for me is (no reset_pin needed):

# relay.ino #117 add a new RELAY_TYPE_STRIKE
digitalWrite(_relays[id].pin, !pulse);
digitalWrite(_relays[id].pin, pulse);
nice_delay(RELAY_LATCHING_PULSE);
digitalWrite(_relays[id].pin, !pulse);

If you can support this relay mode, it's a good news:)

Both codes are equivalent. Instead of creating a new relay type I prefer to support single pin latched relays using the same type. I've added support for it in the dev branch. Configuration will be like this:

    #define RELAY1_PIN          14
    #define RELAY1_TYPE         RELAY_TYPE_LATCHED
    #define RELAY_LATCHING_PULSE 200

(no RELAY1_RESET_PIN)

Well done. Thanks a lot!
