-PSA1259 hardware control using the DeviceController DC2
-
-covering enclosure (switches and doors) and money devices,
-controls mifare card to access or program
-optional it can control printer, modem, bar code reader and credit card
-
- * API to the PSA1259 Hardware
- * All data come in from device controller via serial interface and will be stored
- * in "PI" = peripheral image
- * PI is updated every 100ms (up to 30ms possible)
- * This api uses stored pi data and returns them in the following functions
- * created: Q1/2020 TS
- *
-
-The devices, connected to device controller2 (DC2) can be controlled in different access levels.
-Level 1:
-    direct connection to DC2, check versions, state and parameters
-    control serial interfaces
-    digital/analog IO's
-    read and write to connected devices on lowest level, this is a kind of fall-back-level
-    in case higher levels fail or do not support the needed (new) function
-    Example: send a specific printer command, several bytes that need to be conform to
-            printer manual. This command is routed to the printer through the DC2 without
-            any action of the DC. You can write your own device driver that way.
-    Level 1 is flexible but complicated
-
-Level 2:
-   The DC controls the connected devices containing a device driver. The DC offers
-   usage of the device by simple commands,
-   Example: "Printer on", "set Font size 3" "print "hello world"", "cut"
-   In opposite to level 1 where you had to send a set of numbers and letters.
-   In other words: you "talk" to the device controller, not to the device itself.
-
-Level 3:
-    start/stop complete processes.
-    Example: 1) print (predefined) document nr 3 with Text, letter size, font set, cut.
-                Also power up/down the printer, check if paper ok and so on.

-/*
-Another access example: control the coin unit
-
-Level 1): read digital inputs to detect coin,
-          switch digital output which opens coin slot
-          communicate with coin checker by certain mdb-commands (manual conform)
-          poll coin checker for inserted coins
-          close coin slot after 3seconds by setting DO to 0....
-
-Level 2): get message of attached coin from DC
-          send command "initialize coin checker" to DC
-          send command "open slot for 3s"
-          poll DC for inserted coins, DC polls coin checker in right way, no need
-                to know the data sheet of the coin checker or mdb-bus
-          command to DC "open coin escrow's return flap for 1s"
-
-Level 3): send command: "start payment process"
-          all coin devices are started up
-          coin blocker opens for 3s if a coin is attached
-          coin checker summarizes inserted value and reports sum
-          later send command "stop payment process" (puts coins to vault) or
-          send command "cancel payment process" (returns coins to user)

+    Zunaechst wir immer nachgesehen, ob das Repository bereits geklont wurde.
+    Wenn nein, dann wird geklont. Im Master-Branch befinden sich Dateinen, die
+    in allen anderen Branches gemeinsam genutzt werden. Das sollte wohl auf
+    jeden Fall fuer den DeviceController gelten.
+1:
+    Anfrage bei ISMAS ob neue Daten da sind. Hier faengt die ganze Sache an.
+    Da man nicht weiss, on ISMAS ueberhaupt antworten wird braucht es einen
+    Timer. Man kann die Sache dann auch gleich mehrfach versuchen.
+
+    Die Anfrage geht also per Signal an den Apism-Client. Im Signal wird der
+    Zustand mitgegeben:
+
+        ISMAS_UPDATE_REQUEST_PENDING
+
+    und im Slot dann entsprechend uebernommen. Der Timer sollte nicht im Worker
+    stehen, sondern im Apism-Client. Der Worker sollte damit nicht belastet
+    sein. Der wird dann vom Apism-Client entsprechend benachrichtigt.
+
+        ISMAS_UPDATE_REQUEST_FAILURE
+            ISMAS_UPDATE_REQUEST_TIMEOUT
+        ISMAS_UPDATE_REQUEST_SUCCESS
+
+    Im 1./2.Fall wird dann ein Fehlerhandling durchgefuehrt. Insbesondere
+    wird Apism ueber den DB-Kanal darueber informiert (U0003). Am Ende wie
+    dann wie immer SendCmdVersion und beenden der Applikation.
+
+    Im Erfolgsfall muss in der Antwort der Branch enthalten sein, fuer den das
+    Update durchgefuhrt werden soll. Das ist auch bereits so (Location).
+
+    Ein Sonderfall waere der -m-Modus, da hier niemand auf der ISMAS-Seite
+    aktiv eingreift. Hier braucht es dann einen Ubergabeparameter an 
+    ATBUpdateTool: --branch-name
+
+    Normalfall ist aber die Aktivierung via ISMAS. Dann muss der in der Antwort
+    enthaltene Branch zunaechst ausgecheckt werden.
+2: 
+    Dazu wird ein entsprechendes Signal an den GitClient gesandet.
+        
+        GIT_CHECKOUT_BRANCH_REQUEST
+
+    Der GitClient sieht jetzt erstmal nach, ob es diesen Branch ueberhaupt
+    gibt.
+
+        Falls nein:    
+
+        GIT_CHECKOUT_BRANCH_REQUEST_FAILURE
+            BRANCH_NOT_EXIST
+ 
+        Falls ja:
+            der GitClient versucht nun den Branch auszuchecken. 
+            Geht das gut?
+            Falls nein:
+
+                GIT_CHECKOUT_BRANCH_REQUEST_FAILURE
+                    BRANCH_CHECKOUT_ERROR
+
+            Falls ja:
+                GIT_CHECKOUT_BRANCH_REQUEST_SUCCESS
+                    -> eventl. koennte man den Namen des Branches mitgeben
+
+
+        Signal an den Worker. Im entsprechenden Slot wird jetzt der eigentliche
+        UpdateProzess angeworfen.
+ 3:
+    Mittels git fetch werden jetzt die Aenderungen ermittelt.
+
+        GIT_FETCH_UPDATES_REQUEST
+        
+        GIT_FETCH_UPDATES_REQUEST_FAILURE
+            -> Worker informieren damit Fehlerbehandlung aktiviert wird
+        GIT_FETCH_UPDATES_REQUEST_SUCCESS
+
+        GIT_DIFF_UPDATES
+
+        Die Liste der geaenderten Dateien geht an den Worker. Der kann jetzt
+        noch Test machen, ob das Sinn macht. Evtl. eine Statusmeldung ausgeben
+        drueber was gleich passieren wird.
+4:
+    Mittels git merge/pull werden nun die Dateien tatsaechlich im Branch 
+    aktualisiert.
+
+        GIT_PULL_UPDATES_REQUEST
+        GIT_PULL_UPDATES_REQUEST_FAILURE
+            -> Worker informieren damit Fehlerbehandlung aktiviert wird
+        GIT_PULL_UPDATES_REQUEST_SUCCESS
+            -> Worker informieren
+
+    Sind die Daten vorhanden, dann werden sie mittels rsync ins Dateisystem
+    kopiert.
+
+        RSYNC_UPDATES 
+        RSYNC_UPDATES_FAILURE
+        RSYNC_UPDATES_SUCCESS
+
+    Fuer jede kopierte Datei geht eine Nachricht raus ans ISMAS.
+5:
+    Sind die Daten dann kopiert, so werden sie auf den DC kopiert (falls
+    notwendig): hier gehen dann wieder Nachrichten an ISMAS raus:
+
+        DC_UPDATE 
+        DC_UPDATE_FAILURE
+        DC_UPDATE_SUCCESS
+
+        JSON_UPDATE
+        JSON_UPDATE_FAILURE
+        JSON_UPDATE_SUCCESS
+        
+        Hier fuer jedes Json-File.
+
+    Schliesslich noch eine Zusammenfasung an ISMAS:
+
+        ISMAS_UPDATE_INFO_CONFIRM
+        ISMAS_UPDATE_INFO_CONFIRM_FAILURE
+            -> Worker informieren damit Fehlerbehandlung aktiviert wird
+        ISMAS_UPDATE_INFO_CONFIRM_SUCCESS
+
+    und schliesslich der abschliessende Status an ISMAS zurueckgemeldet:

+While the DC firmware is basically the same for each PSA (even for different
+customers), the PTU software is highly dependent on customer requirements.\par
+Hence, each customer is assigned an own git-repository, which will be loaded
+("cloned") on the PSA when configuring the machine for the first time.\par
+Two special tools, the {\bf UpdateController} (a \href{https://doc.qt.io/qt-5/}{Qt}
+binary [{\bf \nameref{UpdateTool}}]) and the {\bf UpdateScript}
+(a \href{https://www.gnu.org/software/bash/manual/bash.html}{bash}
+script [{\bf \nameref{UpdateScript}}]), work together to finish a PSA installation.\par 
+    
+\section{PSA: Initial configuration}
+
+For the initial configuration, a PSA loads a customer-specific git-repository,
+which structure is detailed below [{\bf \nameref{repostructure}}].\par
+The "git clone" for the repository is done by the UpdateScript [{\bf \nameref{UpdateScript}}].
+It updates the file
+\begin{center}
+    \fbox{
+        /opt/app/tools/atbupdate/update\_log.csv
+    }
+\end{center}
+which will be interpreted by the UpdateController [{\bf \nameref{UpdateTool}}].
+The structure of [{\bf \nameref{updatelogcsv}}] is detailed below.\par
+Each line of update\_log.csv represents a command for the UpdateController,
+which will either download certain files to the DC or execute some
+\href{https://openwrt.org/docs/guide-user/additional-software/opkg}{opkg}
+commands [{\bf \nameref{opkg}}].
+        
+\section{PSA: Update}
+   
+The update of a PSA is basically managed by \href{https://git-scm.com/}{git}, a
+free and open source distributed version control system. Like many other Version
+Control Systems, git has a way to fire off custom scripts when certain important
+actions occur, so-called \href{https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks}{hooks}.
+The hooks used for a PSA update are called {\bf post-checkout} and {\bf post-merge}.\par
+The post-checkout hook is called when checking out some branch of the customer-repository
+(for instance when cloning the customer repository for the first time). In contrast,
+the post-merge hook is called when a \href{https://www.git-scm.com/docs/git-pull}{git pull}
+operation has been issued (more precisely, a \href {https://www.git-scm.com/docs/git-fetch}{git-fetch}
+followed by a \href{https://www.git-scm.com/docs/git-merge}{git-merge}).\par
+Both hooks update the file [{\bf \nameref{updatelogcsv}}], which is interpreted
+by the UpdateController in a second step.

+
+        The update-tool is a Qt binary ("up\_dev\_ctrl") and called by the

+
+        and has two responsibilities:
