s = get_shooting uBasic
s = get_shooting() Lua
Returns 1 resp. true if the camera is currently shooting or has prepared for shooting
and is ready to shoot.
x = get_propset uBasic
x = get_propset() Lua
Returns the type of operating system: 1 = VxWorks, 2 = DryOS.
v = get_prop p uBasic
v = get_prop(p) Lua
set_prop p,v uBasic
set_prop(p,v) Lua
Retrieves and sets properties (section 5.6).
b = get_vbatt uBasic
b = get_vbatt() Lua
Returns the battery voltage into variable b (in milliVolts).
t = get_temperature p uBasic
t = get_temperature(p) Lua
Returns a temperature in degrees Celsius. The variable p specifies the probe:
0 = optics, 1 = CCD, 2 = battery.
u = get_usb_power uBasic
u = get_usb_power() Lua
Sets variable u to a value > 0 if the camera detects a signal on the USB V+ pin. The
returned value is the duration of the signal in units of 10 milliseconds. Typically, this
command is used to implement advanced remote control functions (section 5.7.5).
exit_alt uBasic
exit_alt() Lua
Leaves the CHDK-specific <ALT>-mode (chapter 4). Please note that leaving the <ALT>-
mode interrupts script execution. The script execution is resumed when the camera
returns to <ALT>-mode.

shut_down() Lua
The camera is switched off as soon as possible.
