Hello Friends! In this tutorial I will discuss how to practically do a simple communication over RS232 interface. For those who are completely new to this I clarify that the motive is to send and receive data between two device using a standard called RS232. RS232 is serial interface [...]

Welcome to the 3rd part of RF Communication tutorial. In the last two parts I have introduced the basics of RF Communication. RF Communication Between Microcontrollers – Part I : Introduction to RF Communication and Modules. RF Communication Between [...]

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 function to initialize the USART. That was the first step to use RS232. [...]

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 microcontroller and write the code to initialize the USART and use it to [...]

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 signals. So to interface RS232 level signals to our MCUs we need a [...]

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 I2C. The protocol is such that it automatically synchronize itself. We can use [...]
