Switch modes

Getting Started
1

Hi!
Could someone explain the switch modes or lead me to some kind of documentation?
I get the pin number, refresh rate and invert, but is “mode” parameter?
On DaisySeed

Best regards

There is a little section about it in the docs. Maybe this helps?

It would help if the question was more specific.
LibDaisy? DaisyDuino? What class - Switch, GPIO?

It´s hard to be specific when I don’t know what the different things are :slight_smile:
It´s in Daisyduino, Switch class, this line:

button.Init(1000, true, 28, 0);

So the “1000” is refresh rate. “True” is reversed polarity or not, 28 is pin number . “0” is mode.
So, what kind of modes are there, and how do they work?

Hi & thx!
Well, it almost helps. I´m using the “Switch” class, (in daisyduino) which is mentioned under the “Further reading - topics coming soon…” See my answer to tele_player for the actual line of code I don’t understand.

An important point, which wasn’t mentioned in the original post, was that this is about Arduino. DaisyDuino documentation is even worse than libDaisy.

The mode parameter:

    /** Sets the mode of the GPIO */
    typedef enum
    {
        DSY_GPIO_MODE_INPUT,     /**< & */
        DSY_GPIO_MODE_OUTPUT_PP, /**< Push-Pull */
        DSY_GPIO_MODE_OUTPUT_OD, /**< Open-Drain */
        DSY_GPIO_MODE_ANALOG,    /**< & */
        DSY_GPIO_MODE_LAST,      /**< & */
    } dsy_gpio_mode;

For an object in the Switch class, the only one that makes sense is DSY_GPIO_MODE_INPUT, which has a value of 0.

The DaisyDuino Seed Button.ino example won’t even compile on my system, since it omits the mode argument. My guess - a change was made to DaisyDuino without testing and updating the examples.

As with most of Daisy, the best documentation is the source code. It’s been years now, so I’d say real documentation isn’t forthcoming.

Yes, lets not talk about the documentation…
I suspect that the modes might be pullup or pulldown. The mode I got to work is “2”, with the button wired to ground. I should really just wire up a single switch, try the different modes and monitor on serial. I’ll try to throw in the question in the “Arduino” part of the forum and see if there´s any luck there. Thx!
