Like many ML photographers users, I need to switch between various ML settings, eg ETTR on/off, Dual-ISO on/off, FRSP on/off, Auto bracketing on/off.

For me the following script works.

All it does is toggle between the various settings that are important for me, ie those above.

The script is simple and easily extendable.

To use all you need to do is switch it on and toggle: in LV. The toggled state shows up in the top-right of the ML LV bar.

I have programmed the RATE button as my 'toggler': but this can be changed to another button, ie one you don't use a lot. In the case of my EOSM it uses the KEY.UP. The script detects the EOSM.

In the case of the FRSP, the toggler will check you are in the FRSP permissible range.

One final thing, make sure your ML settings are set to your needs, ie the Toggler simply switches the ML function on and off. For example: I use SET for ETTR and put SNRs and link to Dual to off; I set Dual-ISO to 100/800; enable Auto bracketing and use DNG capture in FRSP. But you choose what works for you.

As usual I welcome feedback.

Cheers

Garry

Some suggestions:

- Don't update the menu entries (menu.set) from the lv.info update callback, do it from the key handler. The update callback gets called over and over again, so you're adding an unnecessary (an probably somewhat large) burden on the CPU, you only need to update the menus when the value change. Callbacks like lv.info update and menu update/info/rinfo/warning should be simple and do as little work as possible.

- You can put the presets into tables and greatly simplify your code (and also make it easier to have more or fewer of them without rewriting code).

presets =
{
    {
        name = "Off",
        menus=
        {
            { menu = "Shoot", item = "Advanced Bracket", value = 0},
            { menu = "Expo", item = "Auto ETTR", value = 0},
            { menu = "Expo", item = "Dual ISO", value = 0},
            { menu = "Shoot", item = "Silent Picture", value = 0},
        }
    },
    {
        name = "ETTR",
        menus=
        {
            { menu = "Shoot", item = "Advanced Bracket", value = 0},
            { menu = "Expo", item = "Auto ETTR", value = 1},
            { menu = "Expo", item = "Dual ISO", value = 0},
            { menu = "Shoot", item = "Silent Picture", value = 0},
        }
    },

-- and so forth

}



play = 1
-- ...

event.keypress = function(key)
    if keymenu.submenu["Turn On/Off"].value == "Off" then
        return true
    elseif key == toggler  then
        play = play + 1
        if play > #presets then play = 1 end
        for i,v in ipairs(presets[play].menus) do
            menu.set(v.menu,v.item,v.value)
        end
        return false
    end
end

lv.info
{
    -- ...
    update = function(this)
        if keymenu.submenu["Turn On/Off"].value == "On" then
            this.foreground = COLOR.YELLOW
            this.background = COLOR.BLUE
            this.value = presets[play].name
        end
    end
}


- It would be nice if you made a way to 'capture' presets. If you use the table scheme above, you can save and load the captured presets using config.


require('config')

toggler_config = config.create(presets)
presets = toggler_config:load()

--at some later time whenever presets are 'captured' or modified:
toggler_config.data = presets
toggler_config:save()

First of all many thanks for your continuing mentorship/education.

I think you know I believe Lua is a fantastic addition to ML and allows us to really make our cameras do some impressive (in-camera) stuff, eg my bracketing script for focus, exposure, LE bracketing.

I had seen others/you use ipairs, but bluntly had not understood the ipairs feature in Lua. With the help of your words above, and looking on line, I now think I get it!

I will rewrite Toggler with ipairs; and your guidance.

Once again, many, many thanks  :)

Cheers

Garry

Once again...many thanks.

It only took me a short period to recode using your hints.

I tidied things up, but had to continue to use lv.info to dynamically check the FRSP shutter.

I also exploited the sequential nature of Toggler, ie I only need to set menu items that previously changed.

Once again, thanks for all your support.

Here is the 'refactored' code  :)

Slight update  ;)

As I realized that I had not reset the Toggler menu items to their OFF state.

The lv.info update is still an inappropriate place to do what you are doing, same goes for menu update. If you want to change menu values based on shutter speed changing, then you should do it from an event that fires when the shutter speed changes. You can set property handler for this. For the menu one, use select instead of update (update runs frequently, select only runs when the user changes the value).

Also this:

if toggler_play == 5 then -- check FRSP values

makes it not 'generic' anymore. I have to have 5 presets and the 5th on and only the 5th one can be FRSP. Instead why not simply read the menu value of silent picture? That way one could simply modify 'presets' to their liking without having to change any other code.

I've got the handler working but I'm getting strange behavior.

Here is the code snippet

function property.SHUTTER:handler(value) -- shutter value changed
   if frsp then -- then need to recheck FRSP values in case user changes shutter speed
display.notify_box (value,3000)
if value < 0.2 or value > 14 then
menu.set("Shoot","Silent Picture",0)
else
menu.set("Shoot","Silent Picture",1)
end
end
end


I added the display.notify to check the shutter value.

I don't understand the units. At 1s I get 56 returned.

Can you help me understand.

Cheers

Garry

dmilligan

Property handlers give you the raw value used by Canon firmware. If you want some nicer unit, use camera.shutter.<whatever>

One final suggestion, you might consider keeping your scripts somewhere like: https://gist.github.com/

That'll give you easy and simple version control amongst other things, and it'll be easier for other users to find the latest version (rather than searching through a forum thread).
