8051 Interrupts

An interrupt is an event that occurs randomly in the flow of continuity. It is just like a call you have when you are busy with some work and depending upon call priority you decide whether to attend or neglect it.   Same thing happens in microcontrollers. 8051 architecture handles 5 interrupt sources, out of

8051 Timers

8051 microcontrollers have two timers/counters which work on the clock frequency. Timer/counter can be used for time delay generation, counting external events etc. Clock  Every Timer needs a clock to work, and 8051 provides it from an external crystal which is the main clock source for Timer. The internal circuitry in the 8051 microcontrollers provides a

8051 Power down and Idle mode

Introduction Power down and Idle mode features are used to save power in microcontrollers. 8051 has inbuilt power saving feature which is useful in embedded applications where power consumption is main constraint. 8051 Power Control Logic 8051 has two power saving mode, Power Down Mode Idle Mode Difference Between Power Down & Idle Mode As

8051 UART

Serial communication means transfer data bit by bit serially at a time, where as in parallel communication, the number of bits that can be transferred at a time depends upon the number of data lines available for communication. Two methods of serial communication are Synchronous Communication: Transfer of bulk data in framed structure at a

Getting Started with 8051 and Keil IDE

8051 microcontroller can be programmed in two languages Assembly language C language 8051 microcontroller popular development IDE is MCU 8051 IDE and µVision to develop code. Keil µVision IDE consists, C Compiler – C51.Exe Assembler – A51.Exe Linker/Locator – BL51.Exe Librarian – LIB51.Exe Hex Converter – OH51.Exe Let’s develop simple LED blinking program using Keil

Introduction to 8051 Controller

Microcontroller consists of all features that are found in microprocessors with additional built in ROM, RAM, I/O ports, Serial ports, Timers, Interrupts and Clock circuits. It is entire computer on single chip which is embedded within applications. Microcontrollers are widely used in many domestic (washing machine, VCD players, microwave oven, robotics etc.) as well as

Using Logic App for IoT remote monitoring and for sending notifications

Introduction Logic App is an Azure service which provides a way to automate processes as a series of simple steps. It can connect across various services and protocols. It begins with some trigger such as ‘When a certain message is received’, followed by a set of actions like ‘Send mail’. This makes Logic App perfect for monitoring

Using Web Apps to Visualize Real Time Data from IoT Hub

Introduction Web Apps is an Azure service for hosting web applications, REST APIs, and mobile backends. It allows development in a number of languages such as .NET, Ruby, PHP, etc. Web Apps empowers your application by adding features such as security, load balancing, auto-scaling and automated management to it. It provides DevOps capabilities such as

Using Power BI to visualize real time data from IoT Hub

Introduction Power BI is a suite of business analytics tools by Microsoft. It can be used to visualize and analyze data from hundreds of data sources and get insights into the data. This makes it useful for visualizing the data received by an IoT hub. We can make use of the various visualization options available
