Ctrl Command set_mcbsp_global_matrix
Function Activates matrix correction for “Global Online Positioning“ by the McBSP interface.
Call
set_mcbsp_global_matrix()
Comments • See also Chapter 8.3.2 ”“Global Online Positioning“”, page 231.
• A matrix correction cannot be used in conjunction with offset and/or rotation
corrections. Any such already-activated options gets deactivated by
set_mcbsp_global_matrix. Subsequent activation of other options (by
set_mcbsp_global_x, set_mcbsp_global_y or set_mcbsp_global_rot) deactivates
the matrix option.
• The following restrictions apply to the matrix coefficients transferred over the
McBSP interface (as with set_matrix
(HeadNo = 4, …)
:
– The allowed value range for matrix coefficients is [–2.0…+2.0].
– Transferred coefficients exceeding this range are ignored.
• Users must individually supply as input value M
in
to the McBSP interface each matrix
coefficient Mij of the transformation matrix M
T
as a normalized integer with associated
indices i and j as follows:
M
in
= ( integer( Mij * 2
28
) << 2 ) + ( i << 1 ) + j
with M
T
= { M00, M01, M10, M11 } = { m
11
, m
12
, m
21
, m
22
}.
Conversely, the RTC6 determines a coefficient from the input value as follows:
M
T
[ M
in
& 0x3 ] = ( M
in
>> 2 ) / 2
28
.
• The coefficients are transferred to internal memory location 1 and can be checked
there by querying with
read_mcbsp(1)
.
• The McBSP interface cannot be simultaneously used for an Online Positioning and
Processing-on-the-fly applications.
