There is some different ways...
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 problem:
In Vivado in the IP Packager when I was trying to make a custom component with mating interfaces to control PCIe4 IP Core, I couldn't do it because in the IP Packager PCIe4 control interfaces were missing, e.g.:
VLNV xilinx.com:display_pcie4: pcie4_cfg_mgmt_rtl:1.0
VLNV...
The problem:
In Vivado in the IP Packager, when we want to set a value for any interface parameter, we won't get any TCL commands in the Tcl Console.
This is probably a bug.
The following images visualize the problem:
The solution:
I managed to find these missing TCL commands :)...

I recently bought Raspberry PI 3 B and was shocked how fast and intuitive were the installation and the configuration.
I have started using Raspbian with NOOBS (the Operating System installer) from https://www.raspberrypi.org/downloads/
NOOBS lets me choose which OS to install...
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.

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...

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...

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...
