How To Configure BIOS In Lenovo/ThinkPad To Enable Virtualization
These days Hardware Virtualization is available in almost all the PCs but most of them don’t have Hardware Virtualization turned on by default. This feature is required to Create and Run Virtual Machines. As steps to enable Hardware Virtualization are different for different models of Computer, I will be covering most of the popular models one by one. In this article, I will talk about enabling this feature in Lenovo/ThinkPad….
Tutorial 2 – How To Program PIC Microcontroller Interrupt in C
We were using polling technique before in which we were waiting for some event to happen, so in that way we were consuming a lot of CPU time by keeping CPU. But in Interrupt method we can do other work and when interrupt happens we may serve that interrupt according to it’s need or importance. PIC Microcontroller has following types of Interrupt- Timer Interrupt Serial Interrupt External Interrupt Port B…
How To Program PIC(18F) Microcontroller In C Using MPLAB IDE
MPLAB IDE is a powerful tool used to program PIC Microcontroller. This software makes several output files of which hex file is used to burn PIC Microcontroller. You can download this software from Microchip site. You can Program any Microcontroller(18F) in C language in this software. Open MPLAB IDE and from Project tab choose “Project Wizard” and from Project Wizard choose “Next“ Select the device you want to use…
How to fix Monitor start problem
In some cases when you start your PC it starts but monitor doesn’t give any response. It keeps blinking but wont start. There are some techniques to check basic faults that may occur. Try these methods step by step until you find your problem. Method 1: 1. First of all check your power. 2. in case of faulty power chord or power plug your monitor wont start. 3. If it…
How to Test PSU of your PC
Sometimes your PC wont start. You want to diagnose yourself but can’t find any fault. Here is the procedure to test your PSU (Power Supply Unit) testing that its working correctly. But before doing this you have to be very careful. I recommend you to do it in the presence of an expert because in PSU output current is high which may cause any damage. 1. Disconnect your CPU…
PIC Microcontroller C Files
Timer0 and Timer1 are used to create two different frequencies using interrupt method Timer0 is used to create a frequency and Timer1 is used as counter to count number of events using interrupt method Port D data is transmit to PC serially and Port B is used to receive data serially from a PC with 9600 baud rate using interrupt method Serial data is send to a PC if switch…
Tutorial 1-PIC Timer Programming In C
So far we are able to provide delay by using for loop, Now in this tutorial we are going to learn how to program PIC Timer in C language. PIC Microcontroller(18f4550) has 4 Timers – Timer 0,Timer 1,Timer 2,Timer 3 Many of PIC 18 timers are 16 bit wide. PIC 18 has 8 bit Architecture so 16 bit timer is accessed as two separate registers of low byte(TMRxL) and high…
How to use Digital Multimeter
Multimeter is powerful Electronics Instrument used to measure voltage diff.,current,resistance,connection short. So,if you are new in “Electronics” field you must know how to operate Multimeter. This article will provide you all information you need about Multimeter. Voltage measurement Current measurement Resistant measurement Short connections hFE value of Transistor Incoming search terms:maltimiter (1)
How to measure Current using Multimeter
Current is measure of flow of electrons in a wire, unlike voltage measurement in this you have to connect the Multimeter in series to those connections in which you would like to know Current value. Rotate your Multimeter’s pointer and make it point toward A sign. Now connect two Multimeter wires to two connections in which you want to see current, you can choose any value between 0 – 1000A….
How to measure AC Voltage using Multimeter
Voltage is potential drop between two points, a simple “Multimeter” can measure up to 750V AC, but it is really not safe to use Multimeter at 750V. But under safety limits we can use Multimeter up to 230V AC. Rotate your Multimeter’s pointer and make it point toward V~ sign, connect two Multimeter wires to two connections in which you want to see voltage ,you can choose any value like…
