Embedded firmware notes for real hardware behavior.
Practical notes on STM32 firmware, motor control, inverter hardware, PWM timing, current sensing, and hardware debugging.
Start Here
Firmware, control, and hardware in one place.
Polezero is for engineers who want to understand how code turns into signals, switching behavior, current feedback, and real debugging work.
Embedded Systems
STM32, timers, ADC, DMA, interrupts, RTOS basics, drivers, bootloaders, and implementation notes.
Motor Control
BLDC, PMSM, FOC, PWM timing, current sensing, startup behavior, and control-loop debugging.
Power Electronics
Inverters, gate drivers, current sensing, protection, PCB constraints, and measurement context.
Model-Based Design
MATLAB/Simulink workflows, generated-code context, validation thinking, and practical tradeoffs.

About Polezero
Engineering notes from the firmware-hardware boundary.
Polezero focuses on the work between control theory, circuits, firmware, and waveforms. The site will grow slowly: useful posts first, topic hubs later.
Publishing direction
- Practical posts before extra navigation
- Diagrams, code context, and measurement thinking
- Topic hubs only after each area has enough useful articles
