RS**2 Serial Camera module
Description:
RS**2 serial camera is new generation of serial camera module, which can be used to snapshot high-definition image through serial interface. Serial camera module get JPG image through a serial port, so this module can be easily integrated into the some device, and let the equipment device has image snapshot function.

Interface:
Command instruction:
1, Reset command: *6, **2, **0
Return: *6, **2, **0
2, Photographing command: *********0
Return: *********0
3, Read the data length of the captured image: *********0
Return: *6 *0 *4 *0 *4 *0 *0 XX YY
XX YY ******- picture data length, XX is the high byte, YY is the low byte
4, Read the picture data: *6 *0 *2 0C *0 0A *0 *0 XX XX *0 *0 YY YY ZZ ZZ
Return: *********0 (interval) FF D8...FF D9 (interval) *********0
*0 *0 XX XX *****- starting address (starting address must be a multiple of 8, generally *0 *0)
*0 *0 YY YY *****- picture data length (high byte first, then low byte)
ZZ ZZ *******- interval (= XX XX * 0.*1 milliseconds, preferably a small number, such as *0 0A)
Note: JPEG picture file data must begin with FF D8, and end with FF D9.
5, Stop shooting: *********3
Return: *********0
6, Set camera image compression command: *6 *0 *1 *5 *1 *1 *2 *4 XX
Return: *********0
XX generally is *6 (range: *0 ***- FF)
7, Set the camera image size: (default size: **0 * **0)
**0 * **0: *6 *0 *1 *5 *4 *1 *0 *9 *1
**0 * **0: *6 *0 *1 *5 *4 *1 *0 *9 *0
Return: *********0
8, Get into sleep mode: *6 *0 3E *3 *0 *1 *1
Return: *6 *0 3E *0 *0
Exit sleep mode: *6 *0 3E *3 *0 *1 *0
Return: *6 *0 3E *0 *0
