4.6.6 McBSP/ANALOG Socket
Connector
The McBSP/ANALOG socket connector
(1)
has 10 pins.
It is located on the upper side of the RTC6 PCIe Board,
see Figure 5.
The McBSP/ANALOG socket connector is a hardware
interface that
• is designed for bidirectional data exchange
(McBSP), see Section ”McBSP Interface”, page 84
and
• furthermore, provides two 10 V analog
input ports: ANALOG IN0 at pin (01) and
ANALOG IN1 at pin (02), see Section ”Analog
Input Ports”, page 86.
The pin-out is shown in Figure 28.
McBSP Interface
The McBSP interface, see Figure 28, is initialized by
load_program_file with:
•
XDelay
=
RDelay
= 1
• 8 MHz clock frequency
Intended for McBSP are pin (03), (05), (07) (outgoing
signals) and pin (04), (06), (08) (incoming signals).
The following signals are continuously outputted
after load_program_file:
• the clock signal at pin (03)
• every 10 µs a frame synchronization signal FSX
at pin (05)
• a data signal DX at pin (07) (Default:
SampleY|SampleX), see set_mcbsp_out
The McBSP interface can be integrated into
applications for various purposes:
• As an alternative to encoder signals, the position
of a moving workpiece can be directly integrated,
see also Chapter ”Correction via
McBSP Interface”, page 245. Prerequisite: Option
Processing-on-the-fly.
• As an alternative to matrix and offset commands,
coordinate transformations can be transmitted
and integrated to align a workpiece with
controllable timing (Online Positioning), see also
Chapter 9.3.4 ”Synchronization and
Online Positioning by McBSP Signals”, page 300.
• With set_multi_mcbsp_in you can transfer not
only a 3D fly correction with position information
but also laser power and other parameters, see
also Chapter ”Correction via McBSP Interface
with Additional McBSP Input”, page 246.
Prerequisite: Option Processing-on-the-fly.
• Permanent data output in 10 µs cycles. With
set_mcbsp_out and set_mcbsp_out_ptr it can
be selected which data signals are outputted.
• OIE Output Mode, page 696 can be set at the
McBSP interface by set_mcbsp_out_oie_ctrl and
set_mcbsp_out_oie_list.
(1) With RTC5 boards referred to as SPI /I2C
socket connector.
