It's extremely easy to take the process of converting source code to machine code for granted. Every day, we write code, but do we understand how the code gets generated? How is the code stored? How does it get ran? By understanding the technical underpinning of these ideas, we can all become better developers. In this video, I'd like to answer a few questions: how do bits become code? How do the thoughts that we have in our head manifest as source code? And how do we take that source code and convert it into a file format that the operating system executes? Finally, how does the operating system execute this file in a way that makes sense.

While this is true, due to thermal, electrical, and memory limitations, alot of the comments in the video were about how CPU's have thousands of cores. In this video, we discuss the subtle differences in GPU microarchitecture, which makes CUDA "cores" and CPU cores significantly different. CPU cores are heavy computing machines, that are able to process arbitrary input from users using arbitrary programs. Because of this, CPUs are more generalized.

Hackers have been trying to steal information since the beginning of the information age. Buffer overflow attacks have been one of the ways they do it. By taking advantage of logic bugs in programs, hackers have been able to get access to computers and steal information which they later sell on the dark web. Buffer overflows have been one of the most common ways they get in. In C, strings are a little weird. Because there is no length encoded with the string type, string functions in C are extremely easy to use incorrectly. When used in an unsafe way, hackers can abuse the way that functions call each other to give them access to your computer. 🏫 COURSES 🏫 https://www.udemy.com/course/c-programming-101-for-aspiring-embedded-developers 🔥🔥🔥 SOCIALS 🔥🔥🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY

When learning to program, one of the first advanced projects you'll get is a networking project. You may even have this in your classes right now where you need to send data from a client to a server and vice versa. This isn't an easy task for a new programmer, and while you should definitely learn the C networking API for Linux or Windows, there's an easier way to do this. ZeroMQ or ZMQ is a message queue library that provides an abstraction over the socket API to make networking easier in C, as well as many other languages. In this video, we go over a basic implementation of the ZMQ library, using a request response schema for a basic networking application.

Adding print statements to debug your crashing program is a tale as old as time. It gets the job done... most of the time. As your code gets more complex and larger, print debugging quickly becomes unfeasible. Using gdb and core files, you can easily cut your debugging time down. In this video, I'll be discussing a pet program that I wrote and using a core file to debug an issue with our program. We'll talk about how to get your program and kernel to produce a core file on segmentation fault, as well as a few techniques to debug C and C++. 🏫 COURSES 🏫 https://www.udemy.com/course/c-programming-101-for-aspiring-embedded-developers 🔥🔥🔥 SOCIALS 🔥🔥🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY

When programming, it's easy to take certain things for granted. One of the easiest things for people to take for granted is the order that memory is stored in. What happens if we forget to consider this when sending data over the network? If a little endian and big endian system mix without properly accounting for byte order, bad things can happen. In this video, I show you what endianness is, and what it means. I'll show you how endianness can manifest as a bug in a program when not considering communication between systems of differing endianness. 🏫 COURSES 🏫 https://www.udemy.com/course/c-programming-101-for-aspiring-embedded-developers 🔥🔥🔥 SOCIALS 🔥🔥🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY

In my previous Rust video, I did some pretty hacky code to get my Raspberry Pi to Blink an LED. We used the Raspberry Pi Datasheet to come up with some hacky unsafe code that enabled a GPIO pin to be an output, and then blinked it on and off. We did this ALL BAREMETAL with no operating system underneath our code. The code WORKED. But, it doesn't port well, and it's not very RUSTY. In this video, I'll take my previous embedded Rust code and make it more Rusty by creating parts to a Peripheral Access Crate. A Peripheral Access Crate or PAC is a component to a Hardware Abstraction Layer in Rust.

In algebra, doing math with negative numbers is simple. By putting a negative sign in front of a number, the number is known to have negative value. But how does this work with binary numbers? Binary numbers cannot be "negative". By saying that a number is either unsigned or signed, the most significant bit of the number will denote if the number is positive or negative, allowing us to do math just like we would with any other number. 🏫 COURSES 🏫 https://www.lowlevel.academy/courses/ 🔥 SOCIALS 🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Support me on Patreon: https://www.patreon.com/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY

One of the hardest things for new programmers to learn is pointers. Whether its single use pointers, pointers to other pointers, pointers to structures, something about the concept drives new programmers crazy. The C programming languages is recognized as one of the most difficult programming languages to learn. The reason for this is the limitless power you have over memory management, which comes from pointers. In this video, I show you what a pointer is, as it applies to low level memory access. Also, we talk about pointer syntax in C and how you can better understand the pointer syntax by converting it to English.

Thread synchronization is easier said then done. If you use a library like pthread for multithreading and mutexes, then you're probably going to be okay. But, if you're writing your own RTOS, figuring out how mutexes work under the hood is really important. Mutexes work under the hood in your OS using atomic operations on the computer processor.

This is the first video of many where we discuss Rust concepts and eventually program embedded platforms with Rust. 🔥🔥🔥 SOCIALS 🔥🔥🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Support me on Patreon: https://www.patreon.com/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY 0:00 Introduction 1:48 Rust Hello World 2:43 Rust Binaries 3:32 Rust "Safety" 5:20 Crashing Rust 6:49 Embedded Rust

The ESP32 by Espressif is an extremely powerful development board. You can use it to give the power of Wifi and Bluetooth to any IOT project you're working on, with zero hassle. In this video, we explore how to setup the Espressif IOT Development Framework, or IDF, and use it to write C code to connect the ESP32 to a Wireless Network. Once the device is connected, we are able to connect the ESP32 to a TCP server and retrieve data from that server. The ESP32 IDF uses FreeRTOS, an open source real time operating system that is used on smaller embedded boards. FreeRTOS allows you to make tasks for different features on your board. Pairing this with the IDF allows you to write powerful Wifi programs to the ESP32. Drop a like and subscribe to be alerted about new videos!

If you're watching this video on any device made in the last 10 years, be it a desktop, a laptop, a tablet or a phone, then there is an extremely high chance that your device is powered by a multi-core processor. Since the release of the first dual core processor in 2005 by IBM, it has become more and more common for computer processors of all varieties to be multi-core. This is in direct contrast to laptops in the 2000's, like my iBook G4 for example, which was powered by a single core PowerPC processor at around 800MHz. Now a days, it is common for any desktop to have at least 4 cores, and clocked easily into the GHz. But what does it mean for a processor to have multiple cores? How does a processor with multiple cores work? Why are more cores better than just one? How many cores are too many? These are all really important questions, and, like you, I was curious to find the answer. 🔥🔥🔥 SOCIALS 🔥🔥🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Support me on Patreon: https://www.patreon.com/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY

Understanding pointers and how to use them is a common problem for people learning new low level programming languages like C/C++. In this video, we dive deep into how pointer arithmetic works in C/C++. Specifically we talk about how the compiler uses the pointer type to do the math for you, making C/C++ pointer math easier than people make it out to be. 🔥🔥🔥 SOCIALS 🔥🔥🔥 Low Level Merch!: https://www.linktr.ee/lowlevellearning Support me on Patreon: https://www.patreon.com/lowlevellearning Follow me on Twitter: https://twitter.com/lowlevellearni1 Follow me on Twitch: https://twitch.tv/lowlevellearning Join me on Discord!: https://discord.gg/gZhRXDdBYY

SQUAD! Welcome back! In this video, we talk about the RISC-V processor architecture. RISC-V was created as an open source processor architecture to get away from the models that Intel and ARM had been using in charging royalties for their process architectures. We talk about how to write a simple "Hello World" for this architecture, as well as how to emulate a RISC-V process on a non-RISC-V system. Drop a like and subscribe to be alerted about new videos!

In this video, we discuss how memory can be allocated to a process when coding in C using the Linux System Call ABI. We talk about how an ELF gets processed and loaded into memory, and how the memory is mapped between the user and kernel space. We go over three seperate methods (malloc, sbrk, and mmap) to allocate more memory to a process other than the predefined stack space that the compiler puts in at compile time.

In this video, we complete our Raspberry Pi 3 GPIO Kernel Driver. Specifically, we add functionality that parses the input from the user and use that to control what pin gets either enabled or disabled. Finally, we write a program that, from user space, is able to control our driver to turn the LED on GPIO 21 on and off. Thanks for watching guys! Code: https://github.com/lowlevellearning/l...

In our previous video, we discussed how to create a driver for the Raspberry Pi. Doing this gave us code execution in the Kernel so that we could legally access addresses otherwise forbidden in user space. In this video, I show you all how to create an interface between the user and the drive via the procfs filesystem. Doing this allows us to access the driver and send data to it from the command line. In my next video, we finish up the driver and control the GPIO pins via our driver from the command line: all in C/C++! Drop a like and subscribe to be alerted when new videos go out.

In this video, we talk about how why GPU's are better suited for parallelized tasks. We go into how a GPU is better than a CPU at certain tasks. Finally, we setup the NVIDIA CUDA programming packages to use the CUDA API in Visual Studio. GPUs are a great platform to executed code that can take advantage of hyper parallelization. For example, in this video we show the difference between adding vectors on a CPU versus adding vectors on a GPU. By taking advantage of the CUDA parallelization framework, we can do mass addition in parallel.

In this video, we talk about the basic concepts of a Real Time Operating System, or RTOS. Also, we go into how to setup a CMake project for the Raspberry Pi Pico to get FreeRTOS on the device. Finally, we discuss how to setup two tasks to blink LED's at different intervals. Without an operating system on your Raspberry Pi Pico RP2040, making programs that execute multiple functions at the same time is extremely difficult. By using an RTOS, you're able to write code in terms of "tasks" that a scheduler runs based on their priority. FreeRTOS is an open source RTOS that allows you to make your Pi Pico projects more powerful.

In this video, we explore different "deep sleep" methods on the Raspberry Pi Pico RP2040. By putting the processor into a "deep sleep" we can use less power during times where executing code isn't important. Deep sleep on the RP2040 allows us to use less power and ultimately make our Raspberry Pi Pico projects way more efficient.

When I started writing code for the Arduino, I felt like the code was abstracted too far away from the processor. While this is the intent of Arduino, I wanted to get down to a lower level. In this video, we learn how to write native C code without any of the Arduino IDE overhead and flash it directly to your Arduino. We go deep into the world of embedded microcontrollers and learn how bitmasks work, how to set and unset flags on a register, and use them all to do the Blink LED in C.

Chapters: 0:00 Intro 0:14 What is Assembly 2:22 ARM Instructions 3:16 Lets Code! 14:50 Outro === okay and how do we do that well let's ask the system call table we need to set r7 to 4. we need to set r0 to the file descriptor we're going to write to which is one we're going to set r1 to the data we're going to write to the screen and then r2 to the length of that data we're adding a few more arguments now so instead of just the r0 before we have r0 r0 r1 and r2 a little more complicated really not that bad all right so what do we say we're going to do the system call is now system call for r0 is now the file descriptor file descriptor one uh we have to set r1 to something right okay what is that something that something is the data we're going to output to the screen let's define that data in the data section that makes a lot of sense right the message so this is a label we're calling the message we're going to write message and it is of type ascii and it's hello world with a new line at the end cool so what does that do we've told the assembler hey in your data section there is an ascii string of this value that we're going to refer to as message ===
