I1 &I2：pod mode, The data type is a 16-bit integer, with the high bit in front and
the low bit in the back, value 1500 for yaw follow mode，1024 for turn to middle
mode （Pitch and yaw return to their original position at boot time），value range
600~2400.
J1 &J2： pitch speed， The data type is 16-bit integer, the high position is in the front,
the low bit is in the back, and 1500 is the median position, indicating that the speed
is zero, and the value range is 600 to 2400.
K1 & K2： YAW speed， The data type is 16-bit integer, the high position is in the front,
the low bit is in the back, and 1500 is the median position, indicating that the speed
is zero, and the value range is 600 to 2400.
O1& O2; Checksum, the sum of all bytes from H1 to N2, the data type is 16-bit
integer, with the high bit before and the low bit after.
