- I am delightful that i have finished implementing the startup code file and linker script file from scratch of Stm32f407VG that based on ARM CortexM4. - Linker script file is used in linking stage to combine all object files with one object file and place layout of memory section addresses. -Startup code is used in reset mechanism to start the main application ; it has 5 main functions : 1.Intializing vector table. 2.Intializing stack pointer. 3.Intializing ".bss" segment. 4.Copy ".data" segment from Flash to RAM. 5.Calling main function. -Startup code use Linker script file to allocate section at memory for vector table and use addresses of sections. 📝 Source Code on my GitHub page : https://lnkd.in/dy5DN9mZ #embeddedsoftware #embeddedsystems #linkerscript #LinkerScripts #memory #microcontroller

I'm thrilled to introduce my latest project focused on Bare-metal programming for the STM32F446re nucleo board. The project is titled "Building Bare-metal Software" and involves the following steps: 1. Creation of a startup file, linker script file, and Makefile to generate an executable file in the format of (.elf). 2. Utilization of OpenOCD as a tool for downloading the executable file into the internal flash memory of the STM32F446re MCU. Additionally, OpenOCD is used for debugging the code with the assistance of GDB. 3. Communication with OpenOCD is established through the use of a Telnet client and a GDB client. I would like to express my gratitude to Amgad Samir for his invaluable supervision throughout the project. If you're interested in exploring the project further, you can find it on GitHub at the following URL: [UsefElbedwehy/Toolchain](https://lnkd.in/dma-jYjy). Feel free to check out the repository for more details and to access the project's resources. #arm #stm #embeddedsystem #toolchain

I installed new memory into my computer. But I don't know why using GPU, system suddenly shutdown without any error. It's good experience to analysis failure cause and create simple checker. I've never think new memory make shutdown symptom in this case. https://lnkd.in/gYR2mZ2e

Excited to share my recent project where I developed a complete driver for the CS5532BS analog-to-digital converter (ADC) using the powerful PIC32MZ2064DAR MIPS microcontroller! 📟 The CS5532BS is a high-precision, low-noise ADC, ideal for applications requiring accurate signal measurement. Integrating it with the PIC32MZ2064DAR, known for its high performance and extensive peripheral options, provided a robust solution for precise data acquisition. 🔧 Tools: MPLAB X IDE and XC32 Compiler for development. Delight in using!🙂 #Microchip #FirmwareDevelopment  #EmbeddedSystems  #mips

I’m thrilled to share the culmination of my journey in ARM Architecture and STM interfacing, where I developed drivers for the STM32F103C8 and STM32F446 MCUs, leveraging the power of Cortex-M3 and Cortex-M4 processors. Using the bluepill (STM32F103C8T6) and Nucleo Board (STM32F446RE), I created a series of small projects to test these drivers, ensuring their reliability and performance in real-world scenarios. Whether you’re diving into embedded systems or looking to explore ARM processors, these drivers could be a valuable resource.

🚀 Exciting News! I've completed the GPIO Driver for the STM32F103 Cortex-M3 and uploaded it to my GitHub repository as part of a comprehensive project to develop drivers for this microcontroller. Check out the GPIO driver here: [https://lnkd.in/dCJG_3sw] 🔧 Features include: - Pin configuration (input, output, alternate function) - Pin state control (set, reset, toggle) - GPIO interrupt handling This achievement is a significant milestone in my advanced diploma program with Eng.Amgad Samir, where I am enhancing my expertise in embedded systems and microcontroller development. Stay tuned for more drivers on the way! #EmbeddedSystems #STM 🛠️📂🖥️

I've did this project last semester in OS course, basically it's a CPU scheduler simulation that simulate scheduling methods in a CPU like FCFS, SJF, Priority, RR support preemptive & non-preemptive modes. #C++

#tinyml #tflite #tf.keras #esp32 *** Machine learning on MCU *** Steps to deploy tinyml (tensorflow lite) on esp32: - Using transfer learning from a pre-trained network - Fine-tuning the model to achieve the best result - Optional: Quantization - Convert the model to CC code - Implement inference code on esp32 Here is a demo that deploys MobileNetV1 on ESP32

refactored the repo, just need to figure out a dynamic way of cutting up the file as much as possible (c nerds get it because it is shared object time) pcb: process control block, stores the context of the process in the kernel memory fdt: file descriptor table, within pcb, this exists as an array keeping track of all the resorces the processor uses. within an os, 2 processes communicate using pipes. over the network line, 2 processes communicate using sockets.

-I am delightful to announce that i have implemented Bootloader of STM32f407VG that based on ARMCortexM4 from scratch ; A bootloader is a piece of code that manages startup, system initialization, and updates for the microcontroller, allowing application software to be reprogrammed without the need for a debugger by different ways of communications. Here’s a brief overview of its role: 1. System Initialization: After a reset or power on, this process configures hardware for software to run on. 2. Loading the OS: The bootloader's main responsibility after the initial setup is to load the firmware or operating system into memory from storage. 3. Software upgrades: Provides effective and safe upgrades for applications. 4.Security Features: Secures software upgrades and provides authentication. 5. Communication Handling: manages protocols such as Ethernet, LIN, and CAN. 📝 Source Code on my GitHub page : https://lnkd.in/dMEy9kpN #embeddedsoftware #embeddedsystems #AUTOSAR #bootloader #BootloaderDevelopment #AutomotiveEngineering #EmbeddedSystems #SoftwareArchitecture #ECU #memory #microcontroller #STM32
