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 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...
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 );

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...
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...
Zero crossing detection is very important, especially in power control circuits employing thyristors.
I have come across many people struggling with zero crossing detection with PIC microcontroller and thus they cannot fire triacs or SCRs as required.
So, here I have explained a simple...

I have previously shown how to implement SPWM in PIC16: https://www.edaboard.com/blog/1800/
Now I will show how to implement feedback for SPWM.
Due to various limitations in PIC16, such as ADC speed, instruction time and the ALU, it is extremely difficult, if not impossible, to calculate in...
As many of us eagerly await the shipping of the new Stellaris LaunchPad, TI has provided us a sneak peek.
TI recently launched the new Stellaris LaunchPad Wiki which contains many interesting and useful links regarding their soon to be shipped, currently sometime in November, Stellaris...
I have previously shown how to calculate the values for the sine table. Now I will show you how to use that sine table for generating a sine wave using a PIC16F684. Why PIC16F684? It is a nice little 14-pin PIC that contains all that is needed for SPWM (sinusoidal pulse width modulation) – the...
Here is the software Smart Sine, that I created and now use to generate sine tables.
It is the improved and more developed version of the software I had previously created with a few more useful features. It is relatively simple to use and gives results quickly as opposed to manually...
The project is aimed at the elderly population and people suffering of cardiovascular diseases. The aim is the creation of a preventive device which would assess and inform of the heart risk. On the other hand, it is not a diagnostic device, able of diagnosing or classifying heart diseases. It...
When we desgin the inductor, we ofter need select which core material shall be used,e.g. MPP, Senduse, Koo Mu,High Flux and Iron Powder, first we consider below these requirements:
1) DC Bias Current through the inductor
2) Ambient Operating Temperature and acceptable temperature rise. Ambient...
For Signal Integrity / Power Integrity simulation analysis, the following model formats could be analyzed:

Dear All
Hi
Thank you for reading my blogs .
As it was my question for long times , and as i understood it is question of many of peoples , when i found it's answer i have decided to put it as simple as possible here . and before that i want say thank you very much to my best friends that...
Atmel AVR Toolchain 3.4.1 Released
A new Atmel AVR Toolchain version has been released, version 3.4.1.
This release primarily is focused on the stability of parts that use the Tiny AVR core (used in the ATTINY 4/5/9/10 devices).
Binaries:
The release binaries (standalone) are available...
As many of the forum members have expressed interest in utilizing an ARM in the development of a project, I thought TI's announcement of their upcoming release of an ARM Cortex-M4F based Launchpad development board for only $4.99 with free shipping to many countries, might be of interest...
Hello Everyone,
If you're willing to convert the values of 0 to 999 Decimal range (8 bit data) into their ASCII values then here is the program with explanation :
(and if you have 16 bit data then I'll post that too, just tell me)
void main()
{
unsigned char x,y,d1,d2,d3...
PFC inductor design
1, selection core:
We should be know below necessary information:
(a) Minimum Inductance based on DC basic, e.g. 1mH
(b) IDC current, e.g. 3A
According to formula LI*I= 1.0*3.0*3.0=9.0
We can find 60u is in range from curve which is LI*I vs core part number, and find...
its a simple frequency counter using the famous atmega 8 of the avr II family micro controllers. it uses counter 2 module of the IC and counts for a period of time. then the value is displayed on a LCD module. its kind of a very vague freq meter, but hey its a start!

PCB Reverse Engineering, also known as PCB CLONE or PCB Copy, is using clone technology onto the PCB which was designed and manufactured by others, it is to use PCB related software to copy someone else’s circuit board and then manufacture the circuit board by yourself. This is the tradditional...
Flexible circuits offer some unique challenges to the assembly process. The assembly materials and processes for populating and interconnecting components to a flexible circuit range are essentially identical to those used for standard rigid or rigid flex pcb, but there are some twists required...
compressing of files is what we all do to reduce the size of the file and to free spaces in our systems but is it worth the time spent for compressing files ?
no.............
why so?
most of our file compressors use lossy algorithm for compressing the files which result in the loss in...
recent study shows that most of the conventional devices have poor efficiency in the order of 30-70%
this has led to the loss of large amount of power in various forms
but recent discoveries in the ever growing field of electronics promise us that the efficiency gap can be nearly equated...

You may have seen the great Oscar winner movie “The secret in their eyes” (If you have not, I advise you to do). However, this is not related to the topic of this blog :roll:. The secret is in the code is not a movie. It is a real situation occurs in almost every team work capacity. It is a...
ok,i'm trying this blog thing to post about a battery charger using PIC12F683
My first goal for this charger is to charge either a single cell or 2 in series. I haven't seen any cheap
commercial single cell chargers, so that provided the motivation.
Many devices use 3xAA batteries, and this...
What exactly is impulse response?
Mathematically speaking an impulse response is the response of a system to an input which is a dirac function (i.e. infinty at t=0 and zero everywhere else). But physically speaking what does this exactly mean? Impulse response of a system is very...
