 ## Voraussetzungen

 ```bash
+# Arch (empfohlen)
+sudo pacman -S cmake qt6-base qt6-serialport

-sudo pacman -S cmake qt6-base qt6-serialport

 # Fedora
 sudo dnf install cmake qt6-qtbase-devel qt6-qtserialport-devel

+V4L2 benötigt keine zusätzliche Library – `linux/videodev2.h` ist Teil der Standard-Kernel-Header.

 ## UART-Ausgabe formatieren

-### Tag-Monitor (`[TAG]`)
+### Raw-View (immer aktiv)

-Der Tag-Monitor fängt Zeilen ab, die ein Tag der Form `[TAGNAME]` enthalten.  
-Das Tag erscheint weiterhin im Raw-View (eingefärbt), wird aber **zusätzlich** im Tag-Panel aktualisiert.
+Jede UART-Zeile erscheint im Raw-View mit Timestamp. Keine besondere Formatierung nötig.

-**Watchdog-Beispiel** – dein Watchdog-Handler schickt:
-```
-[WDG] uptime=12345 free_heap=43210 load=0.82
-```
-→ UARTScope erstellt automatisch ein Panel `[WDG]` mit einer Tabelle:
-
-| Key | Value |
-|---|---|
-| uptime | 12345 |
-| free_heap | 43210 |
-| load | 0.82 |
-
-Jedes Update blinkt kurz grün auf – du siehst sofort, dass neue Daten angekommen sind.
-
-**Mehrere Tags gleichzeitig:**
+**Screen leeren** – von der Firmware aus alle Views gleichzeitig leeren:
 ```c
-// In deinem Baremetal-Code:
-uart_printf("[WDG] uptime=%lu free=%lu\n", uptime, heap_free);
-uart_printf("[VIDEO] line=%d hblank=%d vblank=%d\n", line, hb, vb);
-uart_printf("[AUDIO] buf=%d underruns=%d\n", audio_buf, underruns);
+uart_printf("\033[2J\033[H");
 ```
-Für jeden einzigartigen Tag wird automatisch ein eigenes Panel erstellt.
+
+### Tag-Monitor
+
+Zeilen mit `[TAGNAME]` werden im Tag-Monitor-Panel angezeigt **und** im Raw-View hervorgehoben (cyan). Über „Tag filter…" in der Toolbar können Tags vollständig aus dem Raw-View ausgeblendet werden, sodass sie nur noch im Tag-Monitor erscheinen.
+
+**Format:** `[TAGNAME] key1=value1 key2=value2 ...`
+
+- Tag-Name: Buchstaben, Ziffern, Underscore – z.B. `WDG`, `VIDEO`, `I2C_BUS`
+- Key=Value-Paare: Leerzeichen-getrennt, Werte ohne Leerzeichen
+- Ohne Key=Value-Paare wird der rohe String angezeigt
+
+**Beispiele:**
+```c
+uart_printf("[WDG] uptime=%lu free_heap=%lu temp=%d\n",
+            HAL_GetTick(), xPortGetFreeHeapSize(), core_temp);
+
+uart_printf("[VIDEO] line=%d hblank=%d vblank=%d copper=%d\n",
+            scanline, hblank_ticks, vblank_ticks, copper_dma);
+
+uart_printf("[AUDIO] ch=%d buf=%d underruns=%lu\n",
+            active_channels, buffer_fill, underruns);
+```
+
+Jeder einzigartige Tag bekommt automatisch ein eigenes Panel. Panels aktualisieren sich in-place – kein Scrollen nötig.

 ### Tabellenansicht

+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+		   o---o---o---o---o---o---o---o---o---o "next"
+		  /       /           /           /
+		 /   a---a---b A     /           /
+		/   /               /           /
+	       /   /   c---c---c---c B         /
+	      /   /   /             \         /
+	     /   /   /   b---b C     \       /
+	    /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+	git rev-list ^master ^topic next
+	git rev-list ^master        next
+
+	if these match, topic has not merged in next at all.
+
+To compute (2):
+
+	git rev-list master..topic
+
+	if this is empty, it is fully merged to "master".

+
+# An example hook script to update a checked-out tree on a git push.
+#
+# This hook is invoked by git-receive-pack(1) when it reacts to git
+# push and updates reference(s) in its repository, and when the push
+# tries to update the branch that is currently checked out and the
+# receive.denyCurrentBranch configuration variable is set to
+# updateInstead.
+#
+# By default, such a push is refused if the working tree and the index
+# of the remote repository has any difference from the currently
+# checked out commit; when both the working tree and the index match
+# the current commit, they are updated to match the newly pushed tip
+# of the branch. This hook is to be used to override the default
+# behaviour; however the code below reimplements the default behaviour
+# as a starting point for convenient modification.
+#
+# The hook receives the commit with which the tip of the current
+# branch is going to be updated:
+commit=$1
+
+# It can exit with a non-zero status to refuse the push (when it does
+# so, it must not modify the index or the working tree).
+die () {
+	echo >&2 "$*"
+	exit 1
+}
+
+# Or it can make any necessary changes to the working tree and to the
+# index to bring them to the desired state when the tip of the current
+# branch is updated to the new commit, and exit with a zero status.
+#
+# For example, the hook can simply run git read-tree -u -m HEAD "$1"
+# in order to emulate git fetch that is run in the reverse direction
+# with git push, as the two-tree form of git read-tree -u -m is
+# essentially the same as git switch or git checkout that switches
+# branches while keeping the local changes in the working tree that do
+# not interfere with the difference between the branches.
+
+# The below is a more-or-less exact translation to shell of the C code
+# for the default behaviour for git's push-to-checkout hook defined in
+# the push_to_deploy() function in builtin/receive-pack.c.
+#
+# Note that the hook will be executed from the repository directory,
+# not from the working tree, so if you want to perform operations on
+# the working tree, you will have to adapt your code accordingly, e.g.
+# by adding "cd .." or using relative paths.
