While loop in Embedded C
Hi everyone, i started coding embedded C recently, based on my understanding of While loop it loops over the code as long as the while loop condition remains true, in my simple Led chaser code on ATmega324 bord i was expecting it to break as soon as i released the button switch but the loop kept executing every single line inside it and the LEDs kept lighting up.
i came with a solution which was adding a For loop with an IF statement inside it to check if the push button is still pressed.
but am still wondering why would the while loop keep on going while the condition is not TRUE anymore. "i believe that an IF statement would do that not a while loop"

Sonoff water tank
Has anyone checked the water tank level with "sonoff"? I have many here and some 'float keys'. I would basically work with the idea that: If the float switch makes contact, I have a full water tank, otherwise I need to turn on the pump. Am I traveling a lot?

Why did the value of the rbx register change unexpectedly in GDB?
I am debugging a program on an
x86-64 system Ubuntu 22.04 GDB v10.2 GCC 11.2.0 using GDB and encountered an unexpected behavior. I was inspecting the value of the rbx register and noticed that the value changed from 28 to -5604 without stepping through any new instructions. I am trying to understand what caused this change, as I did not execute any additional steps stepi or similar commands that would modify the register value.
The sequence of GDB commands I used is in my gdb.txt file
The value of rbx initially read as 28 in decimal format, but after running the x/1wd $rbx command, the value changed to -5604. I haven’t taken any further steps stepi or continue, so I’m unsure what caused the value to change...

Why does my assembly network server application cause a segmentation fault?
I'm working on a network server application in assembly language so I can understand low level networking concepts.
So I've implemented a socket server using assembly language system calls, but I'm encountering a segmentation fault during execution.
I have complied the binary on an
Intel Core i7 12700K processor running Ubuntu 22.04 and the NASM assembler ....
Handling Multi-Digit Integer Input in Assembly on Ubuntu 22.04
This
fm_module.txt file has a copy of my project source code that involves a simple user input and arithmetic operations on an Intel Core i7-12700K processor running Ubuntu 22.04.
I've implemented a simple assembly program to take a single-digit integer as input from the user and increment it by one. While the code works correctly for input values between 0 and 9, it fails to handle larger integer values.
How can I effectively handle multi-digit integer input and conversion in How can I effectively handle multi-digit integer input and conversion in assembly?...
Why is the XOR operation not toggling the player variable in my x86 assembly tic-tac-toe game?
I am working on a text based tic-tac-toe game for some users, using x86 assembly on an Intel Core i7 12700K systems running Ubuntu 22.04. I'm using NASM assembler and GNU Linker for development.
I am beginning to have an issue with the
change_player function. The code attempts to toggle the player variable between "0" and "1" using XOR, but the value remains unchanged.
What is causing the player variable to not be modified as expected?
Are there any issues with memory access or data manipulation in the change_player function?...
Segmentation Fault in Assembly Program Using AT&T Syntax and GNU Assembler
I've written a test program using AT&T syntax for use with GNU assembler. The program is supposed to print the value

I was just wondering why this piece of code is not working.
