2.1. Busy Waiting

Many microcontrollers and embedded systems support timer interrupts, allowing the processor to continue executing other tasks while waiting for the timer to expire.

include

When implementing delays in switching, consider the following:

void delay_ms(uint16_t milliseconds) {

```python

volatile uint8_t timer_flag = 0;

Programming a delay in switching is a critical aspect of many applications, requiring careful consideration of both hardware and software methods. By choosing the appropriate delay technique and adhering to best practices, you can ensure reliable and efficient operation in your system.

delay(2) Delays for 2 seconds

import time

return 0;

if (timer_flag) {

```

}

2.2. Timer Interrupts

TIMSK0 |= (1 << OCIE0A);

pass

include

In busy waiting, the program enters a loop, repeatedly checking the time or counting cycles until the desired delay is achieved. While simple to implement, it's not efficient as it ties up the processor during the wait.

while time.time() start_time < seconds:

Programming a Delay in Switching

Software delays offer more flexibility and are often preferred in scenarios where precise control is required. Here are some common methods to implement software delays:

```

}

ISR(TIMER0_COMPA_vect) {

```c

// Do something

TCNT0 = 0; // Reset timer

Usage

delay_ms(1000); // Delay for 1 second

}

sei(); // Enable global interrupts

void delay_init() {

}

Before diving into the programming aspect, it's essential to understand the fundamental difference between hardware and software delays. Hardware delays involve using dedicated components like timers or delay circuits, while software delays are achieved through programming logic.

TCCR0A |= (1 << WGM01);

}

while (1) {

// Usage

timer_flag = 1;

// Initialize timer settings

• Resource Usage: Evaluate the impact of delay methods on processor resources and system performance.

Switching with a delay is a common requirement in various applications, especially in embedded systems and automation. Whether it's to prevent simultaneous actions, allow for settling time, or coordinate events, implementing a delay in switching can be crucial. Let's explore how to achieve this programmatically.

OCR0A = 156; // Set compare value for 10ms delay at 16MHz

```html

}

• Interrupt Handling: Handle interrupts appropriately to prevent delays from being affected.

timer_flag = 0;
