Here I will highlight some features of C language commonly used in 8 bit embedded platforms like 8051, AVR and PICs. While programming microcontrollers in C most of the time we have to deal with registers. ...

When I started using USBasp (a great programmer for AVRs), I soon realized that the avrdude (the software for driving USBasp) is not much usable. Sometimes it irritates me a lots because of its ...

In this turorial we will see how we can easily interface a 24C series serial EEPROM with AVR microcontrollers. What is an EEPROM? An EEPROM is kinds of novalatile memory, that means it is used for storing digital ...

This tutorial give you the details of synchronous serial communication, which is the basis of data transfer in communication standards like SPI and I2C. The tutorial is aimed for a beginner who has no experience or ...

In this tutorial we will set up the TIMER0 in fast pwm mode and use it to generate PWM signals of varying duty cycles. In this way we would be generating analog signals of voltages between ...

In the last tutorial you saw how the PWM technique helps us generate analog signals from a microcontroller. In this tutorial we will see how PWM generation is implemented with microcontrollers. Before you begin please ...

A digital device like a microcontroller can easily work with inputs and outputs that has only two state, on and off. So you can easily use it to control a LED's state i.e. on or off. ...

Till now we have seen the basics of RS232 communication, the function of level converter and the internal USART of AVR micro. After understanding the USART of AVR we have also written a easy to use ...

Merry Christmas !!!

Welcome to the third part of my RS232 serial communication tutorial. Till now we saw the basics of RS232 communication and made our level converter. Now its time to understand the USART of AVR ...

Hello and welcome back. Continuing our discussion on RS232 serial communication in this part we will make a RS232 level converter. In the last tutorial we saw that how RS232 level signals differs from normal logic ...

RS232 is a asynchronous serial communication protocol widely used in computers and digital systems. It is called asynchronous because there is no separate synchronizing clock signal as there are in other serial protocols like SPI and ...
