Abstract: This package contains three tasks, controlling special low
cost process-I/O hardware (DELPHIN-300 System) connected to
the PRO's RTI (Real-Time Interface).  DELTS1 is a menu
driven test program for the DELPHIN-Hardware using the
PRTIL-Calls.  The connections between the PRO's PRTI and the
DELPHIN I/O System is shown in the GIDIS-Metafile
DELCON.GID.  Use the PRO/Sight frame viewer or the print
service with an LA50 to display the picture.
 
The other two tasks DELMCO and DELMEM are parts of a
multitasking application.  In this case, the PRTIL is not
used, but the I/O is done using the device registers of the
PRTI in the I/O-Page directly.  Task DELMEM is a macro task
which performs the actual I/O.  The other task used
(DELMCO) calls the function from DELMEM via subroutines.
These subroutines send and receive messages to and from task
DELMEM.  To map the I/O-Page task DELMEM is a privileged
task.
 
With the multitasking application, you can use the
DELPHIN-300 system's data acquisition facility with the
speed of the ADC used (ca.12KHz).  Higher speeds are
possible (it depends on the ADC's conversion time).  To
solve the problems with the PDP's lack of virtual address
space, MMU-directives are used.  The measured data can be
saved on an RX50 diskette with logical I/O.  Read the
comments in the source files for information about the
functions implemented.
