Electronic Circuits Basics
This article's main target is to teach the electronics language to readers that are not familiar with electronics by using a group of rules and simple equations that describe the behavior of every electronic component and the relationship between the components in the circuit. More ...
Binary Number Representation and Binary Math
Computers perform all of their amazing work with only two voltage levels, one representing binary 0, the other representing binary 1. This article describes how to perform binary addition and subtraction. More ...
Operating System Process Management
A program is not a process. A program is a file containing a list of instructions stored on disk. A process is an active entity with a program counter specifying the next instruction to execute and a set of resources. A program becomes a process when an executable file is loaded into memory. More ...
Arduino Microcontroller Development Platform
The benefit of the open source Arduino Microcontroller Development Platform is that the software is free and the hardware is cheap. This makes it one of the cheapest platforms on which to develop prototypes. More ...
Basic Computer Architecture
Basic computer architecture refers to the structure of a computer system and comprises its hardware, firmware, and software. Hardware consists of the physical components in computer architecture. The main hardware components of the computer architecture include the CPU, memory, and bus. More ...
Learn Assembly Language Programming on Raspberry Pi 400
One of the easiest ways to learn assembly language programming is on the Raspberry Pi 400. The Raspberry Pi 400 is a complete personal computer built into a compact keyboard. More ...
Intel's Core i7 Processors
Core i7 is a family of Intel quad core processors, that is, they have four processors on a single silicon chip. All four processor cores and all memory caches, including a 64K L1 cache, a 256K L2 cache, and a shared L3 cache are located on one chip. The memory is also located on the same chip. More ...
The Microcontroller Interrupt System
Events related to peripheral interfaces are asynchronous to the program running on the CPU. The interrupt mechanism allows an external event to temporarily put the normal execution of the microcontroller on hold and force the execution of a specific subroutine. More ...
ARM Cortex-A72 Registers
16 registers r0 - r15 are accessable in the ARM Cortex-A72 user mode. In addition part of the CPSR (Current Program Status Register) is accessable. That part is the APSR (Application Program Status Register) which contains conditional status bits. More ...
The Microcontroller Memory Map
a microcontroller is a set of resources. Each resource is identified by one or more addresses in an address space. The memory map is a graphic representation of how the resources are associated with addresses. More ...
Microcontroller Architectures
The fundamental microcontroller architectures are Von Neumann and Harvard. More ...
Factors in Choosing an Oscilloscope
An oscilloscope is an instrument used to display the waveform of electronic signals. It draws a graph of the voltage as a function of time. A digital oscilloscope can also store waveforms and perform mathematical analysis of the waveform. More ...
