Hello all,
I am trying to turn on and off a LED connected to RC5 pin of PIC18F4550. But, It is not working.
I read somewhere on the internet that we cannot use RC4 and RC5 pins of PIC18F4550 as Digital Output.
So, Is this true?
Is there any way by which I can connect a LED to the RC5 pin of...
Hello Everyone,
Can anyone tell me, How to implement the delay function for PIC18F4550? I tried the simple for loop for LED blinking, But, LED is not blinking it is simply in ON state.
I used below mentioned simple for loop for delay generation.
void delay1()
{
unsigned int q...
Thanks for replying to my query.
But, when I tested simple LED blinking program on the same breadboard, one thing I found in my breadboard circuit is that there is some problem with crystal,Because, when I touched that crystal, LED started blinking and as soon as I released that crystal, LED...
Hello Everyone,
I am trying to interface 16x4 LCD with PIC18F4550.The simulation in proteus is working fine.But,I am not able to display any characters on LCD (Hardware).
I am getting only Black boxes on LCD screen, and one more thing only two lines are showing black boxes.Other two lines are...
I want to see Virtual Terminal window get opened when I start simulation in proteus. So, that I will be able to see data that I want to send to COM port in virtual terminal (In this case, I want to see "Hello" which I have assigned in my program.)
sorry, I got one correction that is, in 'for...
I am new to serial communication.I am trying to send a string(characters) on RS232 to hyperterminal software. I have tried simulation in proteus but, it is not working at all.
Can you tell me what corrections should I do in my code? What are the wrong things in my code?
Plz, Help.
I am using...
Hello,
I am interfacing ultrasonic sensor with pic18f4550 and want to display my output(sensed value from ultrasonic sensor) on lcd(16x2).
I am using timer1 and crystal oscillator frequency of 20Mhz.
My code is as below:
#include<PIC18F4550.h>
#define _XTAL_FREQ 2000000
#include<xc.h>...
I am trying to generate delay of variable length using delay function in MPLAB X IDE for PIC18F4550.
Crystal Frequency=20MHz.
Basically, I am trying to generate delay of value which will be given as a parameter to delay_us function as shown below:
Such as, delay_us(10) function will generate 10...
Plz, Help me. Not able to get correct values on LCD.
I am interfacing LM35 temperature sensor with PIC18F4550 with 20Mhz frequency.
I tried a lot. But, not getting right output.
Below is my code:
#include<P18F4550.h>
#define RS PORTCbits.RC0
#define En PORTCbits.RC1
void delay()
{
