Watchdog Timer Concept The Watchdog Timer is a timer connected to a completely separate RC oscillator within the microcontroller. If the watchdog timer is enabled, every time it counts up to the program end, the microcontroller reset occurs and program execution starts from the first instruction. The point is to …
Simple Programmer for ATMEGA8 >> ATMEGA 8 used a lot in arduino kits and in this post we will show you how to make a simple programmer for atmega8. Main components : 1) components for the programmer. 2) components for the board Schematic diagram : The board circuit diagram : …
Real Time Clock using ATMega16 Description The ATMega16 chip has a real-time counter that operates asynchronously when a 32,768hz watch crystal is connected to it, providing a real-time clock. The watch crystal needs to connect to pins TOSC1(pin 28) and TOSC2(pin 29). Hardware requirements ATMega16 32,768 KHz crystal LCD …
A somewhat oversimplified view of servlets is that they are Java programs with HTML embedded inside of them. A somewhat oversimplified view of JSP documents is that they are HTML pages with Java code embedded inside of them. For example, compare the sample servlet shown below: import java.io.*; import javax.servlet.*; import javax.servlet.http.*; public …
Testing UART of Atmega16 Here is a simple program to test the UART communication of the atmega 16 >> The UART in atmega 16 can send frames ranges from 5 bits to 9 bits>> In this program we use the assynchronous mode >> The frames used 8 and 9 bits. UART …
Java servlets are more efficient, easier to use, more powerful, more portable, safer, and cheaper than traditional CGI and many alternative CGI-like technologies. Efficient With traditional CGI, a new process is started for each HTTP request. If the CGI program itself is relatively short, the overhead of starting the process can dominate the …
As you traverse the vast frontier of the World Wide Web, you will come across documents that make you wonder, “How did they do this?” These documents could consist of, among other things, forms that ask for feedback or registration information, imagemaps that allow you to click on various parts …
Testing SPI communication Here is a simple code written in c to test the SPI communication using atmega16 the avr code vision compiler is used here. >> In SPI communication : one uc is programmed as a master (initiates communication) and the other uc is programmed as a slave. Here …
Speed and Direction Control of a DC motor >> The pulse width modulation (PWM) mode in timers of ATmega 16 have the main purpose of controlling the speed of a dc motor.>> This is a simple program where the PWM is used to gradually increase the speed of the dc motor …
STK 500 troubleshooting problems Problem A problem occured while executing the command. make sure that you are using the correct programming method.current mode is ISP ………….. SOLUTION ( 1 ) Step 1: >> Go to the tab HW settings in the connection dialog and set the clock generator to max …
When interviewing potential software engineers, most people care for technical competence, for some degree (as a proof of the ability to finish a project), and for a social fit with the current team. Further aspects worth looking for include: amount and kind of project experience; experience in different roles and …
Presuming that you are writing software for the benefit of others as well as yourself, it has to get into the hands of your “users” somehow. Whether you end up rolling a software installer shipped on a CD or deploying the software on a live web server, this is the …
