Timer

Timers are essential peripherals in embedded systems, used for precise control and measurement of time-related tasks. They are hardware modules that count clock pulses and perform operations at specified intervals or durations.

Application of timers

1. Delays:

Create precise delays for debouncing, communication protocols, or other timing-critical tasks.

2. Pulse Width Modulation (PWM):

Generate PWM signals for controlling motors, LEDs, or other actuators.

3. Event Counting:

Count external events like button presses or pulses from a rotary encoder.

4. Frequency Measurement

Measure the frequency or duty cycle of an external signal.

5. Periodic Tasks

Trigger periodic interrupts for tasks like sampling sensors or updating displays.

6. System Monitoring

Watchdog timers help monitor and reset the system if it becomes unresponsive.
