Can you make sub-menu's with the current custom menu tools? I'm working on my menu's and I'd like to make a menu selection that lets me send a specific byte to one of the I2C devices on demand. In this case I want to send a byte telling my sound player to queue up a specific sound byte. I could see it used for other things like which light regime to display from the PWM expansion. It could either ask for a number (byte) to send or it could generate a list (sub-menu) and select with the joystick function. Unfortunately, this is too advanced for my programming skills.
Currently you cannot create sub menus. This adds another level of complexity to the menu system. Submenus exist with the Standard Menu but not with custom menus. I will have to start thinking about this again.
