// msgid, name, crc, minlength, length, type
new message_info(29, “SCALED_PRESSURE”, 115, 14, 16, typeof( mavlink_scaled_pressure_t )),

Where did CRC(the third parameter 115) come from？

That parameter is the CRC_EXTRA added from Mavlink1.0.

You can get if from mavlink. The code generator will create the table that contains the CRC seeds for each messages.
