Summary

This blog introduces microcontroller timers and explains why accurate timing is essential in embedded systems. Readers will learn how hardware timers work, how they interact with interrupts and PWM, and practical uses in firmware such as scheduling, pulse measurement, and low-power timing.

Key Takeaways

• Explain the basic architecture and modes of hardware timers (counters, prescalers, capture/compare).
• Configure timer interrupts to implement periodic tasks and timeouts in firmware.
• Implement PWM generation and input capture for pulse-width measurement and motor/LED control.
• Use watchdog and low-power timer features to improve system reliability and energy efficiency.
• Select appropriate timer resources and strategies for RTOS tick vs. bare-metal timing.

Who Should Read This

Embedded firmware engineers and hardware-oriented software developers (early-career to mid-level) who need to design or debug timing, PWM, and interrupt-driven features on microcontrollers.
