The background: I felt in love with VSCode since I have started to use it! I have to use Keil in my job and honestly - I don't like it much. I was trying to find a working extension to VSCode to integrate Keil's toolchain (build/rebuild/clean) and parse all errors/warnings/infos into VSCode...

Back in the early 1990's, I accompanied our chief engineer to visit Intel. My company had just designed a new high-density pin grid array socket for Intel's new Pentium family. The Intel engineers loved our product and used it in their laboratories for testing. But later during that visit...
Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets...
It's been 4 years since I last posted on the EDAboard. There have been so many changes in the electronics industry. Spring pins are still one of the fastest growing forms of interconnecting two PCBs. The advantages for a designer to use spring pins are numerous: 1) The ability to blind mate two...
Find bellow an Android TCP client extension that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
The following attached file contains a ThingSpeak client extension that allows one to easily make use of the Read and Write features of the ThingSpeak cloud service provided by MathWorks in such a manner that programmer is able to transparently make use of the service without having to deal...
The following attached file contains an SSH Client extension which I made for my own use, but it may also be useful for users of the MIT Application Inventor 2 (AI2) community, or even to the AppyBuilder community (code intrinsically compatible for the last one, but not tested). This is just the...
Note: In earlier versions of the 802.11 standard, the (BCC) OFDM example was given in Annex G. However, an error existed (e.g. in IEEE Std 802.11-2007) in that the FCS was incorrect (see link or search online for "IEEE 802.11-09/0042r0"). The WiFi (802.11) standards documents are free to...
The following function may be useful for those who are starting in the microcontroller's world and wish to implement applications using 7-segment display with the CCS compiler in PIC platform. I've used long time ago: void Display7seg ( char value ) { char pin=0 ; while ( pin< 8 )...
Hi, This project is to build cyclic on-off programmable timer. In this project user can set ON timer and Off time using keys and 7 segment display. Relay is provided as output, where relay will be remained ON for ON time and it will goes OFF after ON time overs. And Relay will remain Off till...
"What programming language skills do employers want? Online job-search firm Indeed took a look at three months (18 May to 18 August) of 2018 job listings in its tech software category to find out. The company ranked programming languages according to the percentage of job postings within the...
Moore’s Law is over, ushering in a golden age for computer architecture, says RISC pioneer David Patterson—University of California professor, Google engineer, and RISC pioneer—says there’s no better time than now to be a computer architect. Some highlights "As an example on the...

In this blog post i will share the OLED libraries with you, which are written for mikroC compiler and can be used with any other C compiler. Following are the functions which are currently present. void OLED_Init( void ); uint8_t OLED_Width( void ); uint8_t OLED_Height( void ); void...
Hello readers, I am writing for my very first post in my very first blog. I would like to share with you some of the bad habits that I used to do at work and fortunately I have changed them into good habits. I would first quote something my brother heard in a finance course a while ago. "A...
Electrical Ground is the reference point in circuits from which voltages are measured. Using the symbol of ground we can make our circuits looks simpler. Three types of electrical grounds are: Simple ground Digital Ground Chassis ground Earth ground Simple ground This type serves as...

By Lee Teschler, Exeutive Editor EEWorldonline.com Ground-fault circuit interrupters (GFCIs) are sometimes also called earth leakage or residual-current circuit breakers. They can sense leakage current to earth ground and interrupt the circuit automatically when leakage current exceeds a...
By Chris Francis (originally appeared on EEWorldonline) I don't mean the transistor radio or mobile phone, but electronic devices and circuits that have been significant and enduring. Some are not necessarily "inventions", depending on how you define an invention, but significant designs...

Those of us who have been in the PCB design business for more than a decade either have direct knowledge of, or have heard the stories about, how the profession has evolved since the late 70’s and early 80’s. The shift from drafting tables, Mylar, and hand taping, to light tables, digitizers and...
By Bill Schweber As the use of LEDs for area lighting has grown dramatically, with both the use of LED-based replacement bulbs as well as LED-based fixtures for new construction (called luminaires in the trade), the issue of dimming these LEDs becomes more critical. LEDs require a very...
By Bill Schweber LEDs – light-emitting diodes – have largely supplanted other sources of light in many applications. They are used in applications ranging from small on/off power indicators, to small and large alphanumeric displays, to screen backlighting, and even for area and street...
Hi everybody! A daily life of an Analog Circuit Designer involves designing transistor sizes :-P , running simulations ;-) across corners :-?, design reviews 8-O, post-layout simulations :-x, sign-off of your checklists :oops: and finally tape-out :clap:. It doesn't stop here :laugh: After...
by Bill Schweber on Analog IC Tips We have already looked briefly at Earth ground (if any), chassis ground, and commons (often misnamed as "grounds"). These do not exist as unrelated connections in a system. The issues related to connecting commons and ground is the subject of countless...
by Chris Francis In 1980, the book "The Art of Electronics" was published, written by Paul Horowitz and Winfield Hill. For many people, myself included, it became the first book you picked up when you needed to know anything related to analog electronics. It was intended as a course textbook...
I am trying to do sparse matrix addition in matlab. 1. Suppose two matrix are give A and B, we have to get the sparse matrix format of the given matrix. This is easily done by sparse function in matlab and categorized accordingly in row, col and val. 2. Now we check the rows and cols of two...
by Janet Heath, EEWorld contributing writer, Tips for preventing problems could fill a book, especially if every professor, technician, or engineer were to contribute tricks and tips that they have learned over the years. However, many will agree that an ounce of prevention is worth a pound...
