QV-10 SERIAL COMMUNICATIONS PROTOCOL
=============================================================================
This document describes the serial communication protocol used by
QV-10's "DIGITAL" connecter. This information is not official.
Rather, it is the result of individual analysis. Please. Do *not*
contact CASIO to ask questions about this information.
You should read source code of 'qvplay' too.
=============================
S E R I A L P R O T O C O L
=============================
* 9600baud 8 bit stop bit 1 Non parity
* No flow control
* RTS off
* CTS,DTR on
CASIO's QV-10 serial cable is a level converter. It converts RS-232C
voltage levels to QV-10's voltage levels. This voltage converter circuit
uses the electrical power supplied by the host computer's RS-232C
connector. (V+ is CTS, V- is RTS.) To receive digital data from QV-10,
set the CTS terminal to ON, RTS terminal to OFF.
On power-up, QV-10 serial communication speed defaults to 9600baud. This
speed may be changed with the'CB' command, described below. This change
remains in effect until power off or another 'CB' command.
-----
===========================
C O M M A N D F O R M A T
===========================
Commands generally follow this format:
0x05 0xXX 0xXX ... 0x06 (hex)
That is, a command flag (0x05, or ENQ) followed by command parameters,
followed by an ACK. (0x06).
======================
C O M M A N D L I S T
======================
above the line: data sent to QV-10
---------------------------------------
below the line: data received from QV-10
ASCII code values are quoted.
All other values are hex.
RESET CAMERA
============
* Reset Camera #1
05 'QR' 06
------------ Reset QV10.
06 5c
Comment:
This command is acceptable, in all states.
The meaning of 0x5c is checksum.
Checksum value is reverse bits of all sum of command bytes and
palameter bytes .
~('Q(51)' + 'R(52)') = 5c
* Reset Camera #2
05 'QE' 06
------------ Reset QV10.
06 69
Comment:
This command does not clear the QV10's LCD.
The meaning of 0x69 is checksum.
QUERY PICTURE NUMBER
====================
05 'MP' 06
-------------- Fetch number of pictures in QV10
06 62 XX
Comment:
Number of pictures in QV10 returned at XX.
The meaning of 0x62 is checksum.
SHOW PICTURE #XX ON LCD
======================
05 'DA' XX 06
---------------- Show picture on QV10's LCD.
06 YY
Comment:
Picture number is specified by XX.
The return byte YY is checksum. (0x7a - XX )

Comment:
XX is the picture number.
The return byte YY is checksum. (0x7a - XX).
Return byte 6f is checksum.
Return byte 6b is checksum.
02 00 00 03 FC should be end marker.
If you want to get 'fine mode(640x480)' picture data in QV100,
you must use 'Mg' instead of 'MG'.

XX is the picture number.
The return byte YY is checksum. (0x7a - XX).
Return byte 6f is checksum.
Return byte 6d is checksum.
Return byte 73 is checksum.
Return bytes ZZ ZZ ZZ ZZ are picture data size.
02 00 00 03 FC should be end marker.
FORMAT OF [Picture Data]
========================
02 WW WW JJ JJ JJ JJ JJ ........ 17 SS
Comment:
WW WW: Data Block Size (2 bytes): (Normally 0x00 0x80, 128 bytes)
The data preceding the endmark(02 00 00 03 FC) is its
block size(under 0x00 0x80).
JJ: Picture data. (JFIF format)
SS: Check sum. Reverse bits of all sum of second byte (after 0x02)
of data block to before SS (0x17).
