The
CHANGE VALUE command must be issued to The Bird in the following N-byte sequence:
MSB LSB
7 6 5 4 3 2 1 0
BYTE #
0 1 0 1 0 0 0 0
#1 Command Byte, 'P'
N7 N6 N5 N4 N3 N2 N1 N0 #2 PARAMETERnumber
B7 B6 B5 B4 B3 B2 B1 B0 #3 PARAMETERdata LSbyte
B7 B6 B5 B4 B3 B2 B1 B0 #4 PARAMETERdata MSbyte
B7 B6 B5 B4 B3 B2 B1 B0 #N PARAMETERdata
Where N7-N0 represent a PARAMETERnumber (i.e. 00000011 or 00000100), and B7-B0
represent N-bytes of PARAMETERdata. If the PARAMETERdata is a word then the Least
Significant byte (LSbyte) is transmitted before the Most Significant byte (MSbyte). If the
PARAMETERdata is numeric, it must be in 2's complement format. You do not shift and add
'phasing' bits to the data.
The
EXAMINE VALUE command must be issued to The Bird in the following 2-byte sequence:
MSB LSB
7 6 5 4 3 2 1 0 BYTE #
0 1 0 0 1 1 1 1 #1 Command Byte
N7 N6 N5 N4 N3 N2 N1 N0 #2 PARAMETERnumber
Where N7-N0 represent a PARAMETERnumber, i.e. 00000000 or 00000001, etc.
If the PARAMETERdata returned is a word then the Least Significant byte (LSbyte) is received
before the Most Significant byte (MSbyte). If the PARAMETERdata is numeric, it is in 2's
complement format. The PARAMETERdata received does not contain 'phasing' bits. The
PARAMETERdata value, content and scaling depend on the particular parameter requested. See
the following discussion of each parameter.
