Question

Write a program using timer 1 to generate a 10KHz square wave frequency on one of the pins of P1.0. Then examine the frequency using the KEIL IDE inbuilt Logic Analyzer. Where XTAL=22MHz.

Answer 1

To generate a 10KHz square wave frequency on pin P1.0 using timer 1 in the KEIL IDE, you would need to program the microcontroller accordingly. After programming, you can use the built-in Logic Analyzer to examine the frequency.

Step-by-step explanation:

To generate a 10KHz square wave frequency using timer 1 in the KEIL IDE, you would need to program the microcontroller accordingly.

Here is an example of the C code that can be used:

#include <reg51.h>

void main()

{

TMOD = 0x10; // Timer 1 in mode 1

TH1 = 0xFA; // Load timer 1 with 256 - (22MHz / (2 * 10000))

TL1 = 0xFA;

TR1 = 1; // Start timer 1

while(1)

{

P1_0 = ~P1_0; // Toggle P1.0 to generate the square wave

}

}

After programming the microcontroller with the above code, you can use the built-in Logic Analyzer in the KEIL IDE to examine the frequency on pin P1.0.
