• After a load_program_file, the McBSP data is
internally permanently acquired and buffered as
soon as (new) data is transmitted. Newer data
words overwrite older ones.
– After load_program_file and/or after
activation of Processing-on-the-fly correction
by set_fly_x_pos, set_fly_y_pos or
set_fly_rot_pos, the input values are stored to
internal memory location 0.
– After activation of an Online Positioning the
input values are stored to internal memory
locations 1 or 2
• For a “Local Online Positioning“ by
set_mcbsp_x, set_mcbsp_y and/or
set_mcbsp_rot or set_mcbsp_matrix, see
Section ”Configuring
“Local Online Positioning“”, page 229
• For a “Global Online Positioning“ by
set_mcbsp_global_x, set_mcbsp_global_y
and/or set_mcbsp_global_rot or
set_mcbsp_global_matrix, see Section
”Configuring “Global Online Positioning“”,
page 231
– The most recent fully transferred values can be
queried from a corresponding memory location
by read_mcbsp.
– After activation of Processing-on-the-fly
correction by set_mcbsp_in or
set_mcbsp_in_list, the input values are
transferred to internal memory locations 0 and
3.
– After activation of Processing-on-the-fly
correction by set_multi_mcbsp_in or
set_multi_mcbsp_in_list, the input values are
transferred to internal memory locations 0
through 3.
Analog Input Ports
The McBSP/ANALOG socket connector
(RTC6 Ethernet Boards: SPI/ANA/UART
socket connector) provides two analog
input ports
(1)
:
• ANALOG IN0
• ANALOG IN1
After the first read_analog_in call, voltages that are
applied there are:
• automatically converted endlessly
(duration approx. 0.3 ms)
(2)
• transferred to the DSP as 12-bit digital values
By the control command read_analog_in, the
present values can be queried at any time.
For technical specifications, see Analog input ports,
page 875.
(1) As with RTC5 PCI Express Boards (but not with
RTC5 PCI Boards).
(2) Note the comment with get_temperature, page 434.
