logon to dev as pwrp
sudo apt-get install ia32-libs git
cd
mkdir rpitools
cd rpitools
sudo git clone git://github.com/raspberrypi/tools.git
create symbolic links to compilers and archiver as a workaround on rather long fully qualified names -
(Proview merge tool has a hardcoded alloc of 80 chars max for the FQ name of each of these tools):
sudo -s
ln -s /home/pwrp/rpitools/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc /usr/bin/arm-gcc

12) Setup the build environment
logon to dev as pwrp
cd
geany ~/.envarm
insert the following into this new file:
  1. .envarm:
  2. env for Proview development for raspberry pi
export pwre_cc=/usr/bin/arm-gcc
export pwre_cxx=/usr/bin/arm-g++
export pwre_ar=/usr/bin/arm-ar

source $pwre_bin/pwre_function
save and exit
geany ~/.bashrc
insert at end of file:
source ~/.envarm
save and exit
close all Terminal(s)
launch Terminal
cd

13) Fixup Proview config script
logon to dev as pwrp
cd /home/pwrp/pwrsrc_4.8.6-3/src/tools/pwre/src/os_linux
cp pwre_configure.sh pwre_configure.sh.org
cd
geany /home/pwrp/pwrsrc_4.8.6-3/src/tools/pwre/src/os_linux/pwre_configure.sh
insert after line 311:
pwre_config_check_lib gtk GTK gtk gtk 0 "/usr/lib/arm-linux-gnueabihf/libgtk-x11-2.0.so"
pwre_config_check_include gtk GTK 1 "/home/pwrp/rpi/include/gtk-2.0/gtk/gtk.h"
as a sanity check, the code block should look like:
if test $pwre_hw == "hw_arm"; then
pwre_config_check_lib gtk GTK gtk gtk 0 "/usr/lib/arm-linux-gnueabihf/libgtk-x11-2.0.so"
pwre_config_check_include gtk GTK 1 "/home/pwrp/rpi/include/gtk-2.0/gtk/gtk.h"
pwre_config_check_include jni JNI 1 $jdk/include/jni.h
pwre_config_check_include jni JNI 0 $jdk/include/linux/jni_md.h
save and exit
pwre init v486_arm
pwre configure
need to figure out some paths, will use the output from "pwre configure" to help,
this is a little tedious:
geany /home/pwrp/pwrrls_4.8.6-3/pwre_arm_linux.cnf
find line "export pwre_conf_libgtk="
note the embedded command, e.g. "pkg-config --libs gtk+-2.0", designate as "cmd1"
find line "export pwre_conf_incdirgtk="
note the embedded command, e.g. "pkg-config --cflags gtk+-2.0", designate as "cmd2". the commands will now be run on the rpi:
ssh rpi3
execute cmd1:
pkg-config --libs gtk+-2.0
save the output in a new temp file, e.g. in geany
execute cmd2:
pkg-config --cflags gtk+-2.0
save the output to the temp file
exit from ssh session
in the temp file, replace "usr/include" with "home/pwrp/rpi/include"
in geany, open /home/pwrp/pwrsrc_4.8.6-3/src/tools/pwre/src/os_linux/pwre_configure.sh
find line "export pwre_conf_libgtk="
hard-code the contents of that assign to the output of cmd1, e.g.:
echo "export pwre_conf_libgtk=\"-lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lglib-2.0\"" >> $cfile
find line "export pwre_conf_incdirgtk="
hard-code the contents of that assign to the edited output of cmd2, e.g.:
echo "export pwre_conf_incdirgtk=\"-pthread -I/home/pwrp/rpi/include/gtk-2.0 -I/usr/lib/arm-linux-gnueabihf/gtk-2.0/include -I/home/pwrp/rpi/include/atk-1.0 -I/home/pwrp/rpi/include/cairo -I/home/pwrp/rpi/include/gdk-pixbuf-2.0 -I/home/pwrp/rpi/include/pango-1.0 -I/home/pwrp/rpi/include/gio-unix-2.0/ -I/home/pwrp/rpi/include/glib-2.0 -I/usr/lib/arm-linux-gnueabihf/glib-2.0/include -I/home/pwrp/rpi/include/pixman-1 -I/home/pwrp/rpi/include/freetype2 -I/home/pwrp/rpi/include/libpng12 \"" >> $cfile
find line "echo "export pwre_conf_lib=\"-lpthread -lm -lrt -lcrypt\"" >> $cfile"
add X11 and db5.1 libraries, e.g.:
echo "export pwre_conf_lib=\"-lpthread -lm -lrt -lcrypt -lX11 -ldb-5.1\"" >> $cfile
find line "echo "export pwre_conf_libdir=\"$conf_libdir\"" >> $cfile"
hard-code the assignment to:
echo "export pwre_conf_libdir=\"-L/usr/lib/arm-linux-gnueabihf -Wl,-rpath=/usr/lib/arm-linux-gnueabihf -Wl,-rpath=/lib/arm-linux-gnueabihf\"" >> $cfile
find line "echo "export pwre_conf_incdir=\"$conf_incdir\"" >> $cfile"
hard-code the assignment to:
echo "export pwre_conf_incdir=\"-I /home/pwrp/rpi/include -I/usr/local/jdk1.7.0_17/include -I/usr/local/jdk1.7.0_17/include/linux\"" >> $cfile
save the edited file
cd
mkdir pwrCustom
save the edited file (again) as ~/pwrCustom/pwre_configure.sh.custom
exit geany
14) Fixup Proview source tree
fix service start script:
cp /home/pwrp/pwrsrc_4.8.6-3/src/tools/pkg/deb_armel/pwrrt/pwr ~/pwrCustom
geany ~/pwrCustom/pwr
for each of the functions: pwr_start, pwr_stop, pwr_reload, pwr_kill:
replace the "whoami" conditional test from "root" to "pwrp"
if using an arduino uno, add the following line within the create_wrapper function, after the umask command:
echo "stty -F /dev/ttyACM0 10:0:8be:0:3:1c:7f:15:1:0:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0" >> $wrapper
save and exit
fix code error:
geany /home/pwrp/pwrsrc_4.8.6-3/sev/lib/sev/src/sev_db.cpp
add open curly brace on line 52:
else if ( type == sev_eDbType_Sqlite) {
add close curly brace after line 58.
code block should now look like:
if ( type == sev_eDbType_Mysql) {
  1. if defined PWRE_CONF_MYSQL
return sev_dbms::open_database();
  1. else
printf( "** Release is not built with mysql\n");
return 0;
  1. endif
}
else if ( type == sev_eDbType_Sqlite) {
  1. if defined PWRE_CONF_SQLITE3
return sev_dbsqlite::open_database();
  1. else
printf( "** Release is not built with sqlite3\n");
return 0;
  1. endif
}
else
return 0;
}
end example code block
save the edited file as:
~/pwrCustom/sev_db.cpp
exit geany
edit the build package script, it will not create a *.deb file as-is:

end example output
there will be some warnings in Workbench Messages re missing files, ignore these
exit from the Proview development environment (close all windows in reverse order of opening them)
19) run the test project
connect to rpi3 via vnc client
nano ~/.xtt_start
edit the rt_xtt invoke to launch the operator station:
$pwr_exe/rt_xtt Nodes-Pipoc-Op &
save changes and exit
sudo nano /etc/proview.cnf
edit the qcomBusId to 5
save changes and exit
sudo shutdown -r now
(so the pwr service will pick up the new bus ID)
connect to rpi3 via vnc client
start the op station:
double-click the Proview desktop icon
launch Display1
verify manually entering a value in Iin is copied to Iout
verify manually entering a value in Iout is overwritten by value in Iin
verify status is green
note: to reset runtime from an abend:
source pwr_stop.sh
---------------------------------------------------------------------------------------------------
OK, proof of concept works, let's have another pi do some I/O
after all, what good is a SCADA system without I/O?
---------------------------------------------------------------------------------------------------
20) Build another rpi (nobody can have just one!), hostname rpi2
install base OS (item 8 above)
config new pi for ssh (item 9 above)
install Proview (item 17 above)
sudo nano /etc/proview.cnf
edit the qcomBusId to 5
save changes and exit
21) configure rpi2 for arduino
login to rpi2 as pwrp
connect the arduino device
sudo apt-get install arduino
launch arduino
pick "Tools | Board | Arduino Uno"
pick "Tools | Serial Port | /dev/ttyACM0"
pick "File | Sketchbook | pwr_arduino_uno"
in sketch, verify debug assignment is 0
verify baudRate is 19200
upload sketch to the arduino
note: due to the bizarre handling of serial in Linux (i.e. raw, cooked, much interference by software layers, etc.),
the following config is needed prior to starting the pwr runtime:
stty -F /dev/sttyACM0 10:0:8be:0:3:1c:7f:15:1:0:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0
this config is included in the "pwr" service start script as per edits in sections above.
(as a side note, if the Uno is connected to a virtual machine via VirtualBox, if you bind the Uno device from the (Windows) host
to the VM using USB and not COM, then things seem to work in Proview debug runtime. Again, the stty config needs to be run prior to runtime start.)
22) Update Proview project
