Скачать или смотреть Turn a NEMA17 Motor with Arduino UNO & CNC Shield V3.0 Using Pure Assembly – No IDE, No Libraries!

In this video, we control a NEMA17 stepper motor using an Arduino UNO and a CNC Shield v3.0 — without using the Arduino IDE or any libraries.
We dive straight into the heart of low-level programming using Assembly language and direct register control as described in the ATmega328 datasheet.

Forget about abstract names like D8 or PB0 — we work only with real register numbers and bits, just like a true embedded systems programmer!
All code is compiled and uploaded directly from the browser using https://costycnc.github.io/avr-compil...

✅ No setup
✅ No drivers
✅ No confusion — just results

👨‍💻 Paste the code, upload, and watch your stepper motor move.
💡 This is real, deep learning for those who want to understand what’s actually happening under the hood.

🚀 Test it now and tell us in the comments if it worked for you!
