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...
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.

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...
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:

The Emergence of Power Integrity Analysis
As the speed of the data signal increases, many reasons including power supply noise lead to the degradation of the high-speed signals. In low power high-speed digital interfaces, it is crucial to characterize the whole system power supply in order to...

LINE FOLLOWER ROBOT
Hi everyone, recently I have created a line follower project, me and my couple of best friends, Creating this Line Follower Robot was not so easy, trust me I have spent many early mornings and couple of sleepless nights, I believe in hard work, I’ve won numerous awards for...
hi friends,
programming of micro controller in assembly takes more time than it in c,but for the assembly lovers its easier to make the programming more friendly by means of the use of macros;
just see the example
in 8051 assembly programming when we are interfacing an LCD
it is necessary to...

Few days ago I was just trying to familiarize an 89C430 microcontroller. I am using SDCC in linux. Then I feel the process of hex loading (ISP) a bit difficult since I need to type the commands and send the hex file using a terminal emulator. Then I wrote a small python script (pyserial based)...
I am working on my final year project "RFID based Access System"..
Here's the code to interface the LCD with 89C51..

Some compilers may have built in functions for these convertions, but others don't. Below are two functions for converting a BCD number to decimal and vice versa:
#define uint8 unsigned char
uint8 BCDToDecimal (uint8 bcdByte)
{
return (((bcdByte & 0xF0) >> 4) * 10) + (bcdByte & 0x0F)...

Finally it transplanted Android system on OMAP3530 development board (from Embest Devkit8000 evaluation), the version of the Linux kernel version is 2.6.27. It feels great. But currently it didn't use OMAP3530 DSP processing on Android that is completely with soft decoding.
It is luck to use a...
In 10 years, smartphones and smart mobile software will certainly do a much better job of gauging context to make our collective user experiences much richer. What do I mean by context? Forrester defines “context” as “the sum total of what your customer has told you and is experiencing at his...
The atmega has a few different PWM modes, the frequency and duty ratio depend on the mode and values used, this is a description of the way to calculate them.
In fast PWM top=ICR1, the output PWM frequency=timer clock/(ICR1+1) and the duty=OCR1A(B)/ICR1
In fast PWM top=0h00ff, the output...
