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...
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.

Following are the functions which are currently present.
void OLED_Init( void );
uint8_t OLED_Width( void );
uint8_t OLED_Height( void );

Time Domain Reflectometry is the analysis of conductor lines (interconnects)by sending a pulsed signal into the conductor and then examining the reflection of that pulse. A TDR transmits a short rise time pulse along the conductor. If the conductor is of a uniform impedance and is properly...
Assumptions:
STM32CubeIDE needs to be installed. At the time of writing this guide, STM32CubeIDE version is 1.6.1 Build: 9958_20210326_1446 (UTC).
OpenOCD and GDB server are already preinstalled in STM32CubeIDE, so no need to install separately;
Keil's .uvprojx project needs to be built to .elf...
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...
Wonder if you know what rental LED display can do for you exactly? Discovering its’ possibilities may help you find new ideas of how to boost your own business and events. That is the reason why we will discuss possible rental LED screen events today - to explain why rental LED screen can play...
The background:
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.
I was trying to find a working extension to STM32CubeIDE to integrate Keil's toolchain (build/rebuild/clean) and parse all...
The background:
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 main purpose of this blog entry is to make STM32CubeIDE project from Keil's project source files.
The solution:
I assume...
The background:
Standards in general are useful as far as they are not overwhelming. In this blog entry I would like to present my embedded project structure. I keep it for every new project for easier navigation throughout project's domains and to speed up project creation.
My embedded project...
The background:
In this blog entry I have shown one way to get a "minimal" Eclipse version. Here I will point to useful plugins and additions.
How to add the Marketplace?
NOTE: The Marketplace is a place where you can add different plugins to the Eclipse.
Go to Help->Install New Software...
The background:
The example solution is focused on the I2C interface.
The walk-through is similar for every single interface.
Adding entry to the board.xml file
Add in <interfaces> section:
<interface mode="master" name="iic_main" type="xilinx.com:interface:iic_rtl:1.0"...
Eclipse installation:
Go to download.eclipse.org/eclipse/downloads/
Find the Latest Release section and click on Build Name (e.g. 4.17):
Scroll down the page and find the Platform Runtime Binary section and click on the appropriate version for your OS:
Download it and install.
Eclipse needs...
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...
Here I have uploaded my designed single cycle 8-bit CISC microprocessor using Verilog HDL. So Let's see and try your own as per your specification.
First of all, as we know CISC microprocessor has separate instruction memory and data memory so here I have make two text file for that and then...
In this post, I will explain the 3 stages of the pipeline microprocessors namely the Fetch Unit, Decode Unit, and Execute Unit. So Let's start designing based on the specification given below.
Stage-1: Fetch Unit
Fetch Unit comprises half-word addressable instruction memory. It takes PC as...
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...

SPICE netlists and other analog source code are getting more complex and more time-consuming to read. Certain new software tools now allow you to define and save SPICE data of a fragment for quick partial simulation, locally or remotely in an external simulator.
Usually, even minor changes in...
Decreasing sizes of semiconductor process geometries and greater number of metal layers, interconnections and components result in a large number of parasitic devices during netlist extraction. This can be problematic for simulation and verification engineers.
Fortunately, SPEF (standard...
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...
SPICE files embody the lowest level of digital and analog circuit behavior in circuit design and verification after place and route. It provides the analog behaviour of transistors and components of digital circuits and gate functions. Multi-layer circuit boards also utilize SPICE, especially if...
FGPA, ASIC or SoC designers use a variety of HDL's (hardware description languages) including Verilog, VHDL or SystemVerilog which can complicate visualization of complex designs. This is particularly the case when having to analyze designs from other engineers in your team and trying to figure...
These days, digital, DFT and mixed-signal engineers have to decipher larger and more complicated System-on-Chip (SoC) functionality, with multiple RTL components and Intellectual Property (IP) blocks obtained from a variety of sources. This can consume hours of engineering time.

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...

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...
