The I²C bus is the most popular of the three current serial EEPROM protocols because of its simplicity, high signal density, and unique write protect (WP) pin characteristics. This illustration shows the typical pin-out of an I²C device with pins 1 through 3 as address pins A0, A1, and A2. Pin 4 is designated as ground, Vcc, while pin 5 is the data line, SDA. The clock signal SCL is at pin 6, pin...

KWP2000/UDS devices are essential tools for anyone who wants to tinker with a vehicle’s onboard computer system. Whether you’ll use yours for chip tuning a hobby-racing vehicle or you need to equip your auto-shop business with better on-board vehicle diagnostics (OBD) programming tools. KWP2000 actually stands for Keyword Protocol 2000, which is the name of a set of communications...

Warnings about bitcoins and other cryptocurrencies are coming from all directions. Concerns about the security of the cryptocurrency have continued to shadow it. Last year, almost 120,000 bitcoin worth around $78m (£58m)were stolen from Hong Kong-based Bitfinex, one of the most popular cryptocurrency exchanges, which resulted in a 20% drop in the value of the currency at the time. Moreover, there...

Universal Plug & Play describes devices that work with a computer system as soon as they are connected. UPnP is an extension of this idea that expands the range of Plug and Play devices to networking equipment. Universal Plug and Play uses network protocols to allow a wide range of devices to be interconnected and work seamlessly with each other. [1] Since most UPnP devices support zero...

The first step is to create a function that compares two input strings, if those strings are an anagram the function will return true or if its not it will return false. Let’s name our function boolean isAnagram(String string1, String string2). Of course, if we compare those strings as they are we can’t find out if they are anagrams, so there is a need to process a little bit those string in a...

Using the  the current project aims to update a board through CANbus. The workflow: The first board has a firmware loaded into the SD Card. At the beginning it requests to transmit the firmware through CANbus. If the second board accepts the request, then the firmware is transmitted through the CANBus to the SD Card of the client. After the completion of the firmware transfer process, the system...

Usually a firmware upgrade of the STM32FXXX boards are is not an easy task for customers. They have to plug the board and use several different tools to flash the memory. For that reason i have made a simple, effective and easy way to upgrade your firmware using an SD Card. The upgrade task is simple, just write your firmware in the first sector of the SD Card (use HxD application to perform this...

Occasionally we might come across a problem which lends itself well to the idea of C# code being compiled at runtime. The .NET Framework includes a mechanism called the Code Document Object Model (CodeDOM) that enables developers of programs that emit source code to generate source code in multiple programming languages at run time, based on a single model that represents the code to render...
