So far we have learned to read digital inputs, analog inputs and use interrupts in ATMEGA8. In this article we will be learning a very important and useful feature if the microcontroller. After reading the article you will be able to send data over the serial port of the controller, to either PC or any RS232 device. Continue reading

This post describes how you can connect a real-world device with virtual-world of Proteus. The usage possibilities are unlimites and hence it breaks the unwanted-barrier between Proteus and Real World. COM Port Physical Interface Model which enables the “physical” serial port of your PC to available to simulation within Proteus. With it you can connect any of the “virtual” component found in Proteus with your PC Serial port. In other word this model connects your physical world with the Proteus-Virtual-World Continue reading

An introductory post on how to use serial communication in PIC Micrcontrollers to send data to PC. What comes first in your mind when you listen serial communication ? Yes, how to send data in series. All this time you have been working single bits, turning on and off. Well serial communication is nothing more than on and off, but the only difference is that it has certain rules and timings which make it the reliable and accurate communication protocol among all.
