+\title{GDB and DASHBOARD}
+\author{}
+\date{}
+\maketitle
+
+\section{Dashboard memory watch}
+Dashboard GDB pozwala na dynamiczne obserwowanie określonych obszarów pamięci. Używając funkcji \texttt{dashboard memory watch}, można ustawić obserwację na konkretne adresy pamięci.
+
+\begin{lstlisting}[language=bash]
+dashboard memory watch 0x1ff80 128 
+\end{lstlisting}
+
+\noindent
+Powyższa komenda skonfiguruje dashboard do obserwacji 128 bajtów pamięci, począwszy od adresu \texttt{0x1ff80}.
+
+\section{Obserwacja pamięci przy użyciu watch w GDB}
+Aby obserwować pamięć na niskim poziomie w GDB, można użyć komendy \texttt{watch} w połączeniu z rzutowaniem i rozmiarem obserwowanego obszaru. Przykładowo, aby obserwować 128 bajty pamięci zaczynając od adresu \texttt{0x1ff80}, użyjemy następującej komendy:
+
+\begin{lstlisting}[language=bash]
+watch *(char*)0x1ff80 @ 128 
+\end{lstlisting}
+
+Ta komenda spowoduje przerwanie wykonania programu, gdy wartości w obserwowanym obszarze pamięci ulegną zmianie. Użycie rzutowania na typ \texttt{(char*)} pozwala na interpretację adresu jako wskaźnika na bajty, a operator \texttt{@} określa ilość obserwowanych bajtów.
+
+\section{Clear Memory}
+
+\subsection{Basic Usage}
+To clear 128 bytes of memory starting from 0x1FF80, use the following script:
+
+\begin{lstlisting}[language=bash]
+#./gdb/zero.py
+
+import gdb 
+for i in range(0, 128): # 128 bajtów
+    gdb.execute("set *((char*)0x1FF80 + %d) = 0" % i)                                    
+\end{lstlisting}
+
+Run this script from GDB dashboard by:
+
+\begin{lstlisting}[language=bash]
+source gdb/zero.py 
+\end{lstlisting}
+
+\subsection{Option 2: With Parameters}
+To dynamically set the starting address, number of bytes, and pattern from the command line, modify the script as follows:
+
+\begin{lstlisting}[language=bash]
+#./gdb/zero_with_params.py
+
+import gdb
+import sys
+
+# Parse arguments from the GDB command
+args = gdb.string_to_argv(gdb.parameter("args"))
+if len(args) != 3:
+    print("Usage: source gdb/zero_with_params.py <start_address> <num_bytes> <pattern>")
+else:
+    start_address = int(args[0], 16)  # Convert start address from hex to int
+    num_bytes = int(args[1], 16)      # Convert number of bytes from hex to int
+    pattern = int(args[2], 16)        # Convert pattern from hex to int
+    
+    for i in range(num_bytes):
+        gdb.execute("set *((char*)%d + %d) = %d" % (start_address, i, pattern))
+\end{lstlisting}
+
+To run this script with parameters, set GDB's `args` parameter before sourcing the script:
+
+\begin{lstlisting}[language=bash]
+set args 0x1FF80 0x80 0x30
+source gdb/zero_with_params.py
+\end{lstlisting}
+
+This allows specifying the starting address, number of bytes to clear, and the pattern to use directly from the GDB command line.
