'Berechnungs-Term'

  • operators:
<< // Bit shift left
>> // Bit shift right
&  // AND
|  // OR
~  // XOR
  • variables:
d0 1st byte (decimal)
d1 2nd byte (decimal)
d3 3rd byte (decimal)
d4 ... 
d5 ...
d6 ...
d7 ...
  • samples:
d0                                         // unsigned char (8-bit)
(d0 - ((d0 >> 7)*256))                     // signed char (8-bit) Two's complement
((d0 << 8) + d1) ^= MSB * 256 + LSB                // unsigned short (16-bit)
(((d0 << 8) + d1) - ((d0 >> 7)*65536))             // signed short (16-bit) Two's complement
((d0 << 24) + (d1 << 16) + (d2 << 8) + d3)                         // unsigned integer (32-bit)
((d0 << 24) + (d1 << 16) + (d2 << 8) + d3)-((d0 >> 7)*4294967296)) // signed integer (32-bit) Two's complement

256 = (1 << 8)
65536 = (1 << 16)
4294967296 = (1 << 32)
