SIGNALS IN LINUX LED TOGGLING UPON RECEIVING A SIGNAL

This tutorial is about Signals. We will explain Linux signals with an experiment showing LED toggling upon receiving a signal. We are going to use C Code for this example. In this tutorial you will need to use serial port and a LED connected to beaglebone board. We are using Beaglebone Black Board for this purpose. But any board on which you can blink LED on Linux can be used.

Using QEMU to Emulate Cortex M based board and Running LED Blinking Program

QEMU is a wonderful tool to emulate Hardware Board. QEMU is also very useful for learner and hobbyist as they can create virtual board and run program on it. This video tutorial explains, Installing QEMU Emulator and configure it to run STM32 Cortex M board (STM32F4-Discovery), Installing GCC compiler and building C program to run Code, Running program on Qemu, Debugging program running on Qemu

How to blink LED connected to 8051 Microcontroller

Let us consider one LED is connected at pin 1 of 8051 Microcontroller. Any 8051 microcontrollers for example AT89C52 Microcontroller from Atmel can be used. Pin # 1 is P1.0 of 8051 microcontrollers.P1.0 is GPIO Port number P1 and bit 0, it is routed to pin # 1 of microcontroller.

Real Time Operating System (RTOS)

Real Time Operating System (RTOS), are used in Embedded System. Now days there are so many vendors in the market which provide RTOS. Some of them are well established also. We try to compile a list of RTOS which are available in market as per our knowledge. This list of RTOS is divided into two categories, Free or Open Source RTOS and Proprietary or Closed Source RTOS.

EMBEDDED LINUX AND DESKTOP LINUX: DIFFERENCE AT A GLANCE

Let us find out the difference between Embedded Linux and Desktop Linux

Linux operating system is used in desktop, servers and in embedded system also. In embedded system it is used as Real Time Operating System. There are so many products in the market that use embedded linux. Embedded system requirements are very much different then requirements of desktop system. Desktop PCs are mostly designed around 8086 architecture of microprocessors. But embedded system products can be designed on various of microprocessor architectures like Power, ColdFire, ARM, 8051, PIC, AVR etc. In embedded system memory is limited, hard disk is not present, display screen is small etc. Embedded system have following other characteristics also like:
Embedded Systems are real time system
Embedded System has less power consumption.

MINICOM: SERIAL TERMINAL IN LINUX

Learn how to use Minicom in linux
Keywords: HyperTerminal in Linux, How to use HyperTerminal in linux, Serial terminal in linux.

Minicom is a text-based modem control and terminal emulation program for Linux operating systems, originally written by Miquel van Smoorenbur. Minicom (Hyperterminal in Windows) is easy and effective used for serial communication between Microcontroller for Testing and Analysis Purpose.
Minicom helps you in Configuring Linux on Board, Running TFTP Server and others. Although, Minicom is very much Similar HyperTerminal in Windows.
But its configuration in quite tricky then of HyperTerminal Read more

Interfacing 16x1 LCD display with 8051

Now a Days, LCD or Liquid Crystal Display are very common for Displaying Alphanumeric characters. The Working of 16 x 1 LCD is Little Bit Different then of LCD 16 x 2.
In Most of Cases 16 x1 LCD is available without Auxiliary Controller. Means as you see only HD44780 Controller at Back Side. In this section we discuss LCD 16 x 1 with no Auxiliary Controller.
