TM Transfer Frame Header Parsing is incorrect #24

Closed MJJoyce closed 6 years ago

MJJoyce commented 6 years ago

TMTransFrame is incorrectly masking out values for the Version and Spacecraft Id fields

Currently

version is being masked out of the first byte with 0xA0
spacecraft_id is being masked out of the first 2 bytes with 0x3F00

Screen Shot 2018-05-03 at 09.36.55.png

This should be:

version should mask out 1100 0000 or 0xC0
spacecraft_id should mask out 0011 1111 1111 0000 or 0x3FF0
