List of all MX-700 commands
Command 4C (see below) returns a list of all the commands supported by
the camera. On my MX-700 it gives the following list:
00 02 07 09 0A 0B 0C 0E 0F 11 13 15 17 19 1B 27 29 30 32 34
4C 51 62 64 80 82 84 86 C0 20 22 2A 2B.
00 - Download thumbnail
Input: frame number (int)
Output: picture data (variable size)
The first bytes of the picture (enough to get the whole Exif header) are
transferred.
02 - Download picture
Input: frame number (int)
Output: picture data (variable size)
The whole picture is transferred.
07 - Change speed
Input: new speed parameter (byte)
Output: errno (byte)
The command prefix is 0x01, instead of 0x00 for all other commands.
09 - Get software version
Input: none
Output: string (variable size)
This command returns "01.00,MX-700" on my digicam.
0A - Get picture name
Input: frame number (int)
Output: the image filename (variable size)
0B - Number of pictures
Input: none
Output: the number of pictures (int)
0C - No operation
Input: none
Output: none
This command does nothing.
0E - Upload picture
0F - Set picture name for upload
11 - Unknown
13 - Unknown
15 - Get name of latest picture
Input: none
Output: picture name (variable size)
17 - Get image size
Input: frame number (int)
Output: picture size (long)
19 - Delete picture
Input: frame number (int)
Output: errno (byte)
1B - Get card status and available space
Input: none
Output: card status (byte), available space (long)
The card status is 0 in the normal case, non-zero for exceptional conditions (no card present,
card not formatted, etc.). It is followed by the free space on the card, which is always a
multiple of the block size (512 bytes), or zero on error.
20 - Unknown
22 - Unknown
2A - Get directory name
Input: directory number (int)
Output: directory name (variable size)
2B - Unknown
27 - Shoot
Input: none
Output: frame number (int), command status (int)
Take a picture. Don't know how to interpret the "command status" part.
29 - Get camera type
Input: none
Output: string (variable size)
This command returns "DIGCAM\MX-700\FUJIFILM" on my digicam.
30 - Get flash mode
Input: none
Output: flash status (byte)
Possible values are: 0 (disabled), 1 (forced), 2 (strobe) and 3 (auto).
32 - Set flash mode
Input: new flash mode (byte)
Output: errno (byte)
34 - Load flash
Input: flash intensity (int)
Output: errno (byte)
The Fuji software uses a value of 200 for the flash intensity. This command can take
several seconds to complete. It should be issued before attempting to take a picture
with command 0x27.
4C - Get list of supported commands
Input: none
Output: string (variable size)
Returns a list of the commands accepted by this camera.
51 - Get command information
Input: command number (byte)
Output: something (int)
I guess the "something" is an indication of how much time the command can take, so
that the software can provide appropriate timeout values. In this case, the
unit is probably something like 1/10 second, so that the timeouts will be
between 0.5 and 20 seconds.
62 - Download preview
Input: none
Output: string (variable length)
The preview is transferred.
64 - Take preview
Input: none
Output: command status (int)
This command should be followed by 0x62 (download preview).
80 - Get camera ID
Input: none
Output: a string (10 bytes)
The "camera ID" is returned. This identifier, stored in the camera's nonvolatile
memory, is 10 bytes long. It is used to fill the "Copyright" field in the
Exif header of pictures.
82 - Set camera ID
Input: new camera ID string (variable size)
Output: errno (byte)
The string is truncated or padded with spaces to be exactly 10 bytes long, and is
stored as the new "Camera ID".
84 - Get date
Input: none
Output: YYYYMMDDHHMMSS (14 bytes)
86 - Set date
Input: YYYYMMDDHHMMSS (14 bytes)
Output: errno (byte)
C0 - Get image information
