Instance Method Details

#strip_redundant_nibble(byte) ⇒ Integer

In the case of something like SystemCommon.new(0xF2, 0x00, 0x08), the first nibble F is redundant because all system messages start with 0xF and it can be assumed. However, the this method looks to see if this has occurred and strips the redundancy

Parameters:

  • byte (Integer) —

    The byte to strip of a redundant 0xF

Returns:

  • (Integer) —

    The remaining nibble
