And there's more: 2.0.4 StateObjects LVRecState

The info below was acquired by sampling state information at 18 times a second.
(ie some of the other states could briefly have been visited ... but only brielfly)

LV state

LV_state 0->2->3->4->2->3->4 (wizzes around). 5% in state 2, 20% in state 4, 75% in state 3. Sometimes (0.1% A state is entered)

When you press magnify LV_state briefly enters -> A -> and -> B -> states

On returning from recording a movie -> C (saving movie to disc) -> D -> back to 2,3,4

LVRec_state

LVRec_state is Zero until Record is pressed: 0 -> briefly to 3 -> 2 (stays here while recording ) -> (then when you stop recording) 6 (stays here until movie saved) -> 0

If you press 'Take photo' button on camera -> 5 ->

2.0.4 StateObjects for LiveView: "LVRecState" and "LVState"Edit

Pointer to 32 Byte StateObject	List of pairs of Value, Subroutine	Keh?	ValSub Pairs	Total Inputs	Total States
aAJ_0x44FC_LV_0x2C_LV_StateObj	aAJ_0xFFC79630_LV_VarSubList	"LVState" Live View State (Not record)	Inputs x States 23 x 14 = 322	23	14
aAJ_0x44FC_LV_0x30_LVRec_StateObj	aAJ_0xFFC7A040_LVRec_VarSubList	"LVRecState" Live View Record State	7 x 7 = 49	7	7

int R0 = LiveViewMgr_struct      [ptr to huge 0x29D8 LVMgr struct]
int R1 = "LVRecState" StateObj   [ie aAJ_0x44FC_LiveView_struct_0x30_LVRec_StateObj]
int R2 = input                   [0..6]

Basic logic:

Next_State = [ aAJ_0xFFC7A040_LVRec_VarSubList + 8 x (7 x input + "LVRecState"_cur_state) ]

Next_Sub() = [0x04 + [ aAJ_0xFFC7A040_LVRec_VarSubList + 8 x (7 x input + "LVRecState"_cur_state) ]

Set "LVRecState".CurState = Next_State

Then BR Next_sub() [There's a little table at the Bottom of the State Objects page to show how this is physically listed in memory]

"LVRecState" State Machine as its stored in MemoryEdit

And so if I list the "LVRecState" VarSubList as a matrix with 7 x 7 we can see how the state machine works.
