The variable p specifies the probe:0 = optics, 1 = CCD, 2 = battery.u = get_usb_power uBasicu = get_usb_power() LuaSets variable u to a value > 0 if the camera detects a signal on the USB V+ pin. Thereturned value is the duration of the signal in units of 10 milliseconds. Typically, thiscommand is used to implement advanced remote control functions (section 5.7.5).exit_alt uBasicexit_alt() LuaLeaves the CHDK-specific -mode (chapter 4). Please note that leaving the -mode interrupts script execution. The script execution is resumed when the camerareturns to -mode.shut_down uBasicshut_down() LuaThe camera is switched off as soon as possible.5.5.11 Low-level commands (Lua only)value = peek(address)Fetches memory content from the specified address.Note: If the address is outside the address range of the camera, the operating systemwill crash! |
