Скачать или смотреть Bare-Metal Embedded Systems (AVR & ARM) in C & Assembly – intro to Arduino Due ATSAM3X8E Cortex-M3

In this episode of the Bare-Metal Programming Series, we introduce the ATSAM3X8E ARM Cortex-M3 microcontroller used on the Arduino Due R3. If you want to learn low-level embedded systems programming, understand ARM architecture, or write register-level C and Assembly code without any libraries, this video gives you the perfect foundation.

You’ll learn:

🔹 The differences between the ATSAM3X8E and 8-bit AVR microcontrollers
🔹 How the PMC (Power Management Controller) and PLL configure the system clock to 84 MHz
🔹 How to locate peripheral base addresses, memory maps, and registers in the ATSAM3X8E datasheet
🔹 Why the onboard LED uses PIOB (PB27) and how it’s mapped to Arduino pin 13
🔹 The essential files needed for a complete ARM bare-metal project:

blink.c – application code

startup.c – vector table + memory initialization

sam3x8e.ld – ARM linker script and memory layout


Whether you're an embedded engineer, a student, or a hobbyist learning ARM bare-metal C, this video explains the critical concepts needed before writing your first program on the Arduino Due.

Next episode: we create a real bare-metal C program for the ATSAM3X8E—no Arduino IDE, no libraries, just the microcontroller at its lowest level.
