Functions codes :
all functions are preceded by escape code (0x1B).
- 0x58 = ping (receive 1 byte = ACK or anything else will be an error)
- 0x53 = get camera informations (receive 256 bytes of informations. Details after this list)
- 0x49 0x3X 0x3X 0x3X 0x3X = get image informations (receive 256 bytes of informations. Details after this list)
- 0x42 0x3X = Set broadcast speed :
0x30 = 9600 bauds
0x31 = 19200 bauds
0x32 = 38400 bauds
0x33 = 57600 bauds
0x34 = 115200 bauds
(In all case, if ok, receive an ACK (1 byte))
- 0x47 0x46 0x3X 0x3X 0x3X 0x3X = Get image
receive 1 byte which contains the ACK (0x6 = all is ok | 0x15 = there is an error)
And by cycle :
receive a part of the picture (512 bytes)
receive a checksum (1 byte)
we must send the result of the checksum (0x6 = All os OK | 0x15 = seems to be an error is happened)
receive information about the transmission (1 byte)
0x1 = next buffer will be transmetted just after
so we must loop
0x4 = finished : we must send an ACK (1 byte) and it's finished
- 0x45 0x46 0x3X 0x3X 0x3X 0x3X = Delete an image (Receive an ACK (1 byte)) Here, we must check if image isn't protected
- 0x45 0x46 0x30 0x30 0x30 0x30 = Delete all images (Receive an ACK (1 byte))
- 0x52 0x90 = Capture an image (Receive an ACK (1 byte)) Here, the camera must be in rec mode !
Camera's Information buffer :
0x00 - 0x02 = Seems to be a signature ? 0x03 0x03 0x02
0x03 - 0x04 = Len of the memory card (or just 0x04 ?!?)
0x05 - 0x06 = Ne serait-ce pas la taille du buffer de données ?! NON !!! ERRONE
0x07 = AC / pile (0 = pile | 1 = AC)
0x08 - 0x09 = Auto-extinction (en secondes)
0x0A = camera's mode (0x0 = play mode | 0x1 = rec mode)
0x0B = LCD (0 = on | 1 = off)
0x0C = Affichage de la barre sur l'écran du numérique (1 = absente | 0 = présente)
0x0D = Flash (0 = automatique | 1 = forcé | 2 = pas de flash)
0x0E = Minuterie (0 = off | 1 = on)
0x0F = Qualité d'enregistrement (0 = Normal | 1 = forte qualité | 2 = économique)
0x10 = white balance (0 = auto | 2 = office | 1 = Day-lt)
0x11 = exposure : 0 à 8 = 0, 0.3, 0.5, 0.8, 1.0, 1.3, 1.5, 1.8, 2.0
0xf8 à 0xff = -2.0, -1.8, -1.5, -1.3, -1.0, -0.8, -0.5, -0.3
0x12 - 0x13 = Images taken (MBR and LBR)
0x14 - 0x15 = Image remaining (MBR and LBR)
0x16 = Sharpness (0 = auto | 1 = sharp | 2 = soft)
0x17 = Color (0 = auto | 1 = light | 2 = deep | 3 = B/W | 4 = Sepia)
0x18 = Pre-flash (0 = off | 1 = on)
0x19 = Focus (0 = auto | 1 = 2.0m | 2 = 0.5m | 3 = 0.1m)
0x1A = Macro (0 = off | 1 = on)
0x1B = Zoom (0 = off | 1 = on)
0x1C - 0x1D = Rapport avec la carte mémoire : surement sa présence + sa taille ??
0x1E = capture (0 = single | 1 = sequence 9)
0x1F = Date display (0 = off | 1 = on)
0x20 = Date display in play mode (0 = on | 1 = off)
0x21 = Date option (0 = M/D/Y | 1 = D/M/Y | 2 =Y/M/D)
0x22 - 0x25 = date and the time
0x25 - 0xFF = seems to be unused
Image's Information buffer :
0x00 - 0x01 = ???
0x02 - 0x03 = maybe the number of the next image ?
0x04 - 0x07 = seems to be Thumbnail size (in bytes)
0x08 - 0x0B = Image size (in bytes)
0x0E - 0x0F = Image number associated to this image info
0x0B - 0x10 = ???
0x11 = Image protected (0x0 = no protection | 0x1 = Image protected)
0x12 - 0xFF = seels to be unused
