3、Read the data length of the captured image: 5600340100
    Return: 76 00 34 00 04 00 00 XX YY
    XX YY ------- picture data length, XX is the high byte, YY is the low byte
4、Read the picture data: 56 00 32 0C 00 0A 00 00 XX XX 00 00 YY YY ZZ ZZ
    Return: 7600320000 (interval) FF D8. . . . . FF D9 (interval) 7600320000
    00 00 XX XX ------ starting address (starting address must be a multiple of 8, generally 00 00)
    00 00 YY YY ------ picture data length (high byte first, then low byte)
    ZZ ZZ -------- interval (= XX XX * 0.01 milliseconds, preferably a small number, such as 00 0A)
    Note: JPEG picture file data must begin with FF D8, and end with FF D9.
5、Stop shooting: 5600360103
    Return: 7600360000
6、Set camera image compression command: 56 00 31 05 01 01 12 04 XX
    Return: 7600310000
    XX generally is 36 (range: 00 ---- FF)
7、Set the camera image size: (default size: 320 * 240)
    320 * 240: 56 00 31 05 04 01 00 19 11
