A480 firmware problem?(solved now)

I tried A480 firmware.
It seems there is a bug.
ubasic command set_prop 16, do not work.
set_prop 16 2
get_prop 16 x
It can set up the value , but it can not control the flash. The flash can be turn on or off only by camera's menu(not chdk menu) setting.
Is there anybody else to try and confirm it?

#16 is the wrong propcase for your camera.
The A480 uses propset 2, so the flash can be controlled with propcase 143 on this camera !

--> http://chdk.wikia.com/wiki/PropertyCase#Digic_III_.26_Digic_IV

Here's a little sample script, written by msl, published in the german forum ([1]).
This script should work with all cameras using propset 1 or propset 2; propset 3 is not yet supported, but can be added easily when somebody add the propcase to the wikia table...

Code: (lua) [Select]

--[[
@title flash row sample
]]

function fastshoot()
  	press("shoot_half")
  	repeat
    	sleep(1)
  	until get_shooting() == true
  	press("shoot_full")
  	release("shoot_full")
  	release("shoot_half")
  	repeat
   	 	sleep(1)
  	until get_shooting() ~= true
end

function set_flash_mode(n)
	if get_propset() == 2 then
		set_prop(143,n)
	else
		set_prop(16,n)
	end
end

flash_state = get_flash_mode()
set_flash_mode(2)
fastshoot()
set_flash_mode(1)
fastshoot()
set_flash_mode(flash_state)
