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...
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...
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...
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...
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...

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...

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 );

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...

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...

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...

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...
