Question:

I need help designing a microcontroller project using the $8051$ in C language. The project involves:

Generating and Measuring Frequencies:

Use an RTC module $($e$.$g$.,$ DS$1307$ or DS$3231)$ to generate a $1$ Hz square wave on its SQW pin.Connect this $1$ Hz square wave to the $8051\text{'}$s external interrupt pin $($INT$1).$

Internal Frequency Generation:

Configure the $8051\text{'}$s Timer$0$ to generate its own $1$ Hz signal.

Pulse Comparison Over $10$ Seconds:

Count pulses from both sources $($RTC and $8051\text{'}$s timer$)$ over a $10-$second interval.After $10$ seconds, compare the two pulse counts.

Display the Results:

Use a $16$x$2$ LCD to display:

Line $1$: RTC$-$generated pulse count.Line $2$: $8051-$generated pulse count.

The LCD should use $4-$bit mode for communication.

Requirements:

Provide the circuit design in Proteus.

Code should be written in C for the Keil compiler.

Specify all connections clearly, including the RTC$,$ LCD, and interrupt pins.

Ensure the RTC is configured via I$2$C for a $1$ Hz square wave output.

The program must reset the counters and repeat the measurement$/$display every $10$ seconds.

Deliverables:

Proteus simulation file.

Well$-$commented C code for the $8051$ microcontroller.
