Edit Menu problem.

[cyberdevnet]

Hi Kris, Thanks for your wonderful library :) Im having a litte headache getting around this problem, I'm creating an Editmenu where I can scroll/select a number of predifined options, those options are in a char array like this:

const char *MidiINChannels[17] = {"ALL","1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16"};

MidiINMenu.init(MENU_TEXT, MENU_BACKGROUND, MENU_HIGHLIGHTTEXT, MENU_HIGHLIGHT, MENU_SELECTTEXT, MENU_SELECT,DATA_COLUMN, ROW_HEIGHT, ROWS, "Midi IN settings", FONT_ITEM, FONT_TITLE);

MidiINOption5 = MidiINMenu.addNI("Midi Channel", <??? what here ??? >, 0, sizeof(MidiINChannels) / sizeof(MidiINChannels[0]), 1, 0, MidiINChannels); 

If I want to pre-populate the option let say with value "ALL" taken from my flash if this value is a String and addNI is expecting a float? Is the data parameter the index of my char array?

I hope it's clear what I'm trying to say/achieve 😄

The "what goes here"  is the array element (0-16), You just set the initial value to first element (0) for "All" Like this: MidiINOption5 = MidiINMenu.addNI("Midi Channel", 0, 0, sizeof(MidiINChannels) / sizeof(MidiINChannels[0]), 1, 0, MidiINChannels);

Another option I use all the time is to store the value in eeprom, I read the value at startup so the last menu item selected is presented as the default on next startup, then if the users uses the menu to change the value, I store the new setting in the eeprom.

Thanks, Kris @.***

I was able to fix in this way:

float tempselectedMidiChannel;

    if (selectedMidiChannel == "ALL")  // value taken from flash
    {
        tempselectedMidiChannel = 0;
    }
    else
    {

        tempselectedMidiChannel = selectedMidiChannel.toFloat();
    }

    MidiINOption5 = MidiINMenu.addNI("Midi Channel", tempselectedMidiChannel, 0, sizeof(MidiINChannels) / sizeof(MidiINChannels[0]), 1, 0, MidiINChannels); // midi IN Channell select

in this way I can cast the String taken from flash to the float needed by the addNI method
