Write a program to get data from port B and send it to port C continuously while an interrupt will do the following: One of the timers will toggle pin PD5 every 100 microseconds. In place of port B, port C, and PD5 pin you can use ports of your own choice.

Please Help trying to learn Assembly ( Try to make as simple as possible) ATMega328PB

**Instruction for Activity 1: Interrupt Implementation** Add the following interrupt to Activity 1: A square wave is connected to an external interrupt, and any time a low-to-high (L-to-H) pulse comes in, a single LED is turned on. Conversely, any time a high-to-low (H-to-L) pulse comes in, the LED is turned off. The rate at which the LED turns "On" and "Off" corresponds to the frequency of the square wave.

**Educational Program Overview** This program will help you to write code that manages data transfer between ports and utilizes interrupts for specific timing tasks. The objective is to create a continuous data flow between two ports and implement a timer interrupt for toggling a pin. **Task Details:** 1. **Data Transfer:** - Acquire data from port B. - Continuously send this data to port C. - You can select any ports you prefer instead of port B and port C. 2. **Interrupt Handling:** - An interrupt will be set up to operate a timer. - This timer toggles pin PD5 every 100 microseconds. - Pin PD5 is flexible, allowing you to choose any pin for this purpose. By completing this program, you will gain an understanding of port operations, continuous data transfers, and the use of interrupts for precise timing control. **Note**: Ensure to handle data efficiently and manage any potential conflicts that might arise from simultaneous operations on the ports and pins.

Expert Solution
Step 1: Answer Overview:

Requirements:

  1. Continuously read data from Port B and send it to Port C.
  2. Use an interrupt such that a timer toggles pin PD5 every 100 microseconds.

Setup:

  • For this task, I'll use Timer1 to generate the interrupt every 100 microseconds.

1. Setting up Timer1 for Interrupt:

To generate an interrupt every 100 microseconds, you need to set the appropriate prescaler and count value for the timer. Here's a quick calculation:

The ATmega328PB runs at 16MHz by default. To get an interrupt every 100 microseconds:

Required timer ticks = (16M * 100e-6) = 1600

Timer1 is a 16-bit timer, so it can count from 0 to 65535. We will use the CTC (Clear Timer on Compare Match) mode.

Now, if we use a prescaler of 1:

Compare Value = 1600 - 1 = 1599

So, the Timer1 counter should be set to trigger an interrupt when it counts up to 1599.
