In this blog post i will share my Graphical Lcd libraries with you which are written for xc8 compiler in MPLAB-X development environment.
The libraries functions are inspired from mikroC functions and i tried to keep most of the functions similar to the one available in mikroC compiler.
Some...

Generating Sine wave is very demanded job in power electronics field. So do to me too. I read some topics over the internet and found many ways to generate a sine wave. As most of you are really interested in generating sine wave so I’m writing today about it here.
There is some different ways...
HSM-20G is one of the most common humidity and Temperature sensor. This sensor is fully analog type. The outputs are analog voltages rather than any digital signal.
The datasheet indicates that the output pins need some extra devices with it. here is the connection diagram:

Introduction:
Specifying the correct printed circuit board pad, land and, hole sizes are critical to the device mechanical attachment of a machined pin or socket.
Through-hole PCB designs come in two flavors: plated and unplanted.
A plated hole provides a path for solder wicking due to...

I have to use Keil in my job and honestly - I don't like it much.
The debug is great, but the editor is lacking in many features compared to other IDEs.

The background:
The example solution is focused on the I2C interface.
The walk-through is similar for every single interface.

Introduction:
For round pins with precision critical diameters, multiple barrel diameter variations, and drilled holes, CNC machining is the ticket. For the other one-billion-part applications, metal forming, and fabrication processes offer the best solutions.
Consider the following...
Introduction:
One of the most overlooked, least thought-out components assembled to a PCB is the pin terminal. Although they’re not exciting like logic devices, they can present complications to those who disregard their correct application.
Consider the profit loss of fully populated PCBs...
Introduction:
Reducing height and space is always a goal in new product design. Reducing module space translates into cost savings. For rackmount assemblies, space is limited between printed circuit boards. Low-profile carriers eliminate permanent onboard insulators minimizing socket...
Hand assembly and soldering of individual pin arrays to a PCB is inefficient, costly, and results in poor product quality. Yet, some manufacturers are still doing this.
One old-school production soldering method employed for thru-hole PCB assemblies is called wave-soldering. To accomplish...
Introduction:
Which quagmire have you experienced lately?
Case 1: Your production assembly schedule goes off the rails due to QA finding random misaligned surface mount connectors due to migration during reflow.
Case 2: You’re taking returns due to field failures; fatigued surface mount...
Introduction:
Manually placing fields of discrete pins upon a printed circuit board is a poor production PCB assembly strategy. This action is not only tedious and prone to errors but extremely cost-ineffective too.
Vertically unstable pins tilt, creating harmful soldering rework. Misaligned...
Have you ever had this experience?
After placing a purchase order, the supplier discovers they cannot manufacture the promised part.
Because you did not plan properly, you have no choice but to buy an expensive, unproven custom product. With no prior reference history, you are the...

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...

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").

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:

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...
