Common Instructions Types in PIC Microcontrollers
Every microcontroller family has its own set of instructions that are typically carried out in a similar set of operations though using different syntax. This is exhibited in the variation in the internal architecture of various types of microcontrollers. Processors such as those fabricated by Intel have a more extensive instruction set, with more options…

6 Types of Microprocessor Addressing Modes
Microprocessors perform operations on data stored in the register or memory. This data is specified in the operand field of the instruction. The data can be specified in various ways as direct data value or stored in some register or memory location, and so forth. These are referred to as the addressing modes of the…

The MOV Instruction in Intel 8051 (MCS-51) Microcontroller
The MOV instruction tells the CPU to move (in actual fact COPY) the source operand to the destination operand. Programming in assembly language requires that at least you understand the architecture of the microprocessor or microcontroller you are working with; this means that we need to be well-versed with things like registers in that specific…

Basic Microprocessor Instructions
Microprocessors perform various basic operations that include data transfer instructions, arithmetic instructions, logic instructions, control transfer instructions and machine control operations. This set of commands (instructions set) used to control the functions of a microprocessor is specific to a given microprocessor. In this article, we look at examples of these instructions focusing on Intel 8085…

An Overview of Assembly Language for Programming Microcontrollers
Introduction Software is the term used for the instructions that tells a microprocessor or microcontroller what to do. The collections of instructions that a microprocessor will recognize is its instruction set. The form of the instruction set depends on the microprocessor focused on. Microprocessors operate in binary code. The instructions written in binary code are…

PIC Microcontroller Input-Output Ports Programming in C
PIC microcontroller input-output ports are named PORTA, PORTB, PORTC, etc. depending on the type of microcontroller you are using. Port pins can be in analog or digital mode. In analog mode, ports are input only and the in-built analog-to-digital converter and multiplexer circuits are used. In digital mode, a port pin can be configured as…

What is Embedded Java?
Embedded Java is a Java version that makes large program development simpler by providing complete object-oriented programming (OOP) features in Java. JVM is configured to minimize memory requirements and run-time overheads in the system. Embedded System programmers use Java in a large number of readily available classes for the IO stream, network and security. Java…

10 Reasons to Consider Java for Embedded Systems Programming
Java as a high level programming language has grown over the years into a full-fledged language with an enormous user base. It is used extensively for instance, in building web applications with frameworks such as Spring Boot. Java has also found a formidable utilization in programming embedded systems, and this is due to the following…
