Dear Friend
Your question is very ambiguous and i cant understand what your problem really is? U have to clarify your question to get answer from the members.
I assumed that you want to interface 4*4 keypad and LCD. You want to do something in which you want to get data from Keypad using rows...
U can use transistor as a switch to control a relay(electromechanical switch) for controlling a single device with a bit. If u want to control more devices one at time (rarely needed) u can use a decoder between the transistor and microcontroller.
Hope this helps

Dear Mr.Cube
Thanks for giving an attention to my question. For ur info, i know how to make PWM, in fact i have generated 2 PWM signals using PIC16F877 in the background. The problem is that it just have 2 PWM channels and i need 4. that's why i wanna learn ECCP module in PIC18F4550. The data...
Californiajoe has given a good idea, but still its not working.
I think there is some mistake in ur code. I have downloaded the attachment, but it doesnot contain the (.PBP) file we have to check. It contains another file. PLZ attach the correct one so that i may be able to help u.

Dear i m unable to understand what u really want to do? I guess that u want to control the speed of DC motor. If yes then do me know i can send u some sample codes plus circuit diagram for that.

My friend if u r interested i can send u the full version of this software. Moreover you dont need MPLAB to work with software, its stand alone, but u can do so because MPLAB plugin of this software is also available in the full version.

Dear friend
I can help u to solve this problem and also send u some sample codes, but u have to switch the compiler from Sourceboost to CCS info PICC. R u interested? If yes do me know. Best of luck

There are some things which i have assumed during the conversion, see the comments
START: BTFSS PORTB, 0
GOTO START
GOTO LOOP
LOOP: NOP
BSF PORTC, 1
CALL DELAY_MS ; in this code DELAY_MS subroutine is not defined, i assume that u have defined it...
Hi guys
I m doing a project in which i want to generate 4 PWM signals of approx. 1KHz frequency in the background (means i want to do other micro-controller tasks and PWM simultaneously). I m using PC18f4550 for this purpose. I have found that i can generate 4 PWM signals in the background by...
Dear i think u experimenting GPS 4 the first time, so i advise u to buy GARMIN ETREX LEGEND gps unit, which i am using at this time.
By the way below are the some links, which may help u 2 buy the unit.

Have u simulated your code on proteus? If it is working properly in simulation, then there may b problem in your circuit or configuration settings. Also try the following code in simulation.
#include <18f45k20.h>
// #include <stdio.h> // no need of this file
#fuses...
GSM modems have serial ports, u can send AT commands to gsm modem via a microcontroller's or PC's serial port to control it.
Dear for interfacing gsm modem with pic16f877, u must first understand the following basic (u may skip if u already know):
1) Serial communication of PC with PIC...
Hey guys
Currently im worked on my servo motor control problem as i have discussed in earlier discussion, i have simulated my circuit n code in proteus its working fine, i guess that my servo is faulty or it has been destroyed...
Can any one tell me how i can chek my servo is faulty or...
Dear Frndz can any1 give me some ideas about how 2 rotate servo with some defined speed? I know how to control the angle of servo. My servo's range is 180 degrees not 360 degrees. Any help will b appreciated...
