Why ProgPtr
Built the way embedded is actually learned
From first principles to firmware on a real board — no hand-waving, no paywalls.
Real chips & boards
8051, AVR, PIC, STM32, ARM and Renesas — register-level, on hardware you can buy.
Free downloads
Schematics, cheat-sheets, datasheets and complete source — free to grab and reuse.
Build projects
Every track ends in something that runs — a clock, a meter, a driver, a small product.
Tracks
Start where it clicks
Three paths that meet in the middle — pick the one that matches where you are.
Roadmap
Your Learning Path
Begin by mastering C and C++, the essential languages for embedded systems, basic electronics, and microcontrollers — then build up, step by step, to complete firmware.
