Lua script - enhanced tv mode for all cams

This is a little script for a enhanced  tv mode. It should be work for all cams (with or without tv mode).

You can select a tv value from 64s to 1/10000s.
You can use the zoom while running the script.
You can select a focus mode.
Continuous shooting is possible.

the console menu:

[<-][->]  select a tv value
[UP][DOWN]  zooming
[DISP.]  select a focus mode
[SET][Remote]  shooting
[MENU]  exit

In the script parameter menu you can adjust the start value of tv, the key delay und the shoot delay.

Code: (lua) [Select]
--[[
@title Tv mode universal
@param a integer value  [Tv]
@default a 0
@param b key delay [ms]
@default b 80
@param c shoot delay [s]
@default c 0
]]
 
function print_Tv()
tv_output = {"64s","50s","40s","32s","25s","20s","15s","13s","10s","8s","6s",
"5s","4s","3.2s","2.5s","2s","1.6s","1.3s","1s","0.8s","0.6s","0.5s","0.4s",
"0.3s","1/4s","1/5s","1/6s","1/8s","1/10s","1/13s","1/15s","1/20s","1/25s",

"1/8000s","1/10000s"}
print_tv = "Tv  : "..tv_output[tv_input+19]
end

function mf_mode()
mf_output = {"normal","macro","","infinite"}
print_mf = "focus: "..mf_output[mf_input]
end

function button()
local x = 0
repeat
wait_click(key_delay)
if is_pressed "remote" then
  key = "SET"
  x = 1
end
if is_pressed "set" then
key = "SET"
x = 1
end
if is_pressed "menu" then
key = "MENU"
x = 1
end
if is_pressed "display" then
   key = "DISP"
   x = 1
  end
if is_pressed "left" then
key = "LEFT"
x = 1
end
if is_pressed "right" then
key = "RIGHT"
x = 1
end
if is_pressed "up" then
   key = "UP"
   x = 1
  end
  if is_pressed "down" then
   key = "DOWN"
   x = 1
  end
until  x == 1
set_led (8,1)
sleep (10)
set_led (8,0)
end

--script start

if a < -18 then a = -18 end
if a > 40 then a = 40 end
if b < 50 then b = 50 end
if c < 0 then c = 0 end

repeat
if get_mode() == false then
cls()
print("No record mode!")
print("Stop for changing.")
sleep(3000)
exit_alt()
sleep(2000)
end
until get_mode() == true

tv_input = a
key_delay = b
shoot_delay = c
max_zoom = get_zoom_steps()
zoom = get_zoom()

repeat
if get_propset() == 2 then
mf_input = get_prop(6)+1
else
mf_input = get_prop(11)+1
end
cls()

button()

if key == "DISP" then
mf_input = mf_input + 1
if mf_input == 3 then mf_input = 4 end
if mf_input == 5 then mf_input = 1 end
if get_propset() == 2 then
set_prop(6,mf_input-1)
else
set_prop(11,mf_input-1)
end
end
if mf_input == 2 then
set_zoom(0)
else
if key == "UP"  then
zoom = zoom + 1
if zoom > max_zoom then zoom = max_zoom end
set_zoom(zoom)
end
if key == "DOWN" then
zoom = zoom - 1
if zoom < 0 then zoom = 0 end
set_zoom(zoom)
end
end
if key == "RIGHT" then tv_input = tv_input + 1 end
if key == "LEFT" then tv_input = tv_input - 1 end
if tv_input > 40 then tv_input = -18 end
if tv_input < -18 then tv_input = 40 end
if key == "SET" then
if shoot_delay > 0 then
cls()
print("wait "..shoot_delay.." s")
sleep(shoot_delay * 1000)
end
TV = tv_input * 32
press "shoot_half"
repeat
      until get_shooting() == true
if get_propset() == 2 then
set_prop(262,TV)
else
set_prop(69,TV)
end
press "shoot_full"
release "shoot_full"
release "shoot_half"
end
until key == "MENU"
Edit: A little bit safer, using only in record mode possible. You need a new CHDK version rev. 545

Sounds cool, and can be really useful.

When I run it this is all I see:

uBASIC:1 Unk stmt

Copied directly from this post and saved as-is. I've done this with dozens of other scripts that did work, so that's not the problem.

It's erroring out on this (apparently) Lua line:

It's a lua script, not a ubasic script. Either you've renamed to something other than .lua, or your are running a really old build that doesn't have lua support.

First ran it on Juciphox build 543, then tried it on build 544 downloaded tonight. Same thing.

Oh well. So much for "lua" being helpful.

Then you didn't correctly name it with a .lua extension.

... or you didn't use a 'compile complete' build - check if your CHDK/LUALIB folder is present

First and subsequent attempts: script filename = enhanced_tv_mode.lua

CHDK/LUALIB/ Folder and files, present and accounted for.

Used both the posted version (copy paste method) and attachment.

Results: "uBASIC:1 Unk stmt"

As I said, Oh well.

trying with an 8.3 name might help (yours is 16.3 , and CHDK, especially with dryos, is not windows !)

(edit: can't check on dryos, but long name lua scripts do work OK on VxWorks, tested on a620)
