This program uses an ATmega8535 microcontroller to light up LEDs connected to port A in sequence when button 0 on port B is pressed and turn them off in reverse order when button 1 is pressed. It initializes ports A, B, C and D, sets port A pins as outputs and lights up each pin on port A for 50ms when button 0 is pressed, then turns them all off when button 1 is pressed also with a 50ms delay between each pin.

DDAA FPGA - Multiplexor De Numeros en Display 7 Segmentos En Tiempo
This document describes the design of a 4-display multiplexing system to sequentially display the values of a 8-bit incrementing counter. The design includes:
1) An 8-bit incrementing counter module
2) A hexadecimal to 7-segment display decoder
3) A 4-input multiplexer to sequentially activate each display
The modules are instantiated and interconnected in a top level module to increment the counter value and sequentially multiplex the output to the four displays on the Nexys 2 board. Simulation waveforms verify the correct functionality of incrementing the counter value and sequentially multiplexing the displays.

Exception handling in C++ allows programs to handle runtime errors and unexpected situations called exceptions. Code that could cause exceptions is placed in a try block. If an exception occurs, it is thrown to a catch block that handles the exception. C++ supports multiple catch blocks to handle different exception types based on the parameters passed to throw. This allows catching specific exceptions while resuming normal execution when no exception occurs.
Programação completa e perfeira
This document contains code for an Arduino-based car alarm system that can be activated and deactivated remotely via a cell phone. It initializes an LCD display and defines pins to control a buzzer, relay, and input from a sensor. The main program loop displays status messages, sounds the buzzer in short bursts when the sensor is triggered to indicate activation is in progress, and enables the relay to lock the car after a 6 second countdown is displayed. It then shows a locked message and waits for further sensor input.
An introduction to PHP 5.4
This document introduces PHP 5.4 and provides an overview of new features and changes from previous versions. Some key additions in PHP 5.4 include improved performance, always available short echo tags, closure support for $this, class member access on instantiation, and a built-in development web server. The document also discusses how to switch to PHP 5.4 on Gentoo Linux and provides useful links for more information.

Php arduino
This document provides code to connect an Arduino board to PHP code running on a computer. The Arduino code receives serial input from the PHP code to control an LED, turning it on or off depending on whether a 0 or 1 is received. The PHP code uses a serial communication class to open the serial port, send the data to control the LED, then close the port.
Os Practical Assignment 1
The document describes the implementation of locks and conditions variables in an operating system project. It includes code for a Lock class that uses a semaphore to synchronize access with its Acquire and Release methods. It also includes code for a Condition class that allows threads to wait on and signal conditions, managing a wait queue of semaphores. The document concludes by briefly explaining the dining philosophers problem in concurrent programming and some potential solutions like using tokens to establish turns.

This code is used to detect sighs from a patient and send a signal to a mobile device. It reads analog sensor data to calculate a sliding average breath value and compare it to a threshold. When the average exceeds the threshold for a possible sigh, it monitors for the average to drop below a level to confirm the sigh. Upon detection, it sends a signal over a serial connection and lights an LED for one second.

Codigo
This code configures an ADC to read an analog signal from channel 0, converts it to a digital value, displays the value on an LCD, and sets the state of PORTB pins based on whether the value is below 25, between 20-25, or above 25. It initializes the ADC and LCD, sets an infinite loop to continuously read the ADC value and check/display the condition.

The document describes a mini 4x4 keypad calculator that connects an HC11-CPU microcontroller to a LCD display. It includes code for scanning the keypad, performing basic math operations, and displaying results on the LCD. Key functions include entering numbers, selecting operators, clearing values, and calculating results when the equals key is pressed.
R tist
The document describes several Arduino sketches. The first sketch uses an array of pin numbers to light up LEDs in sequence using a for loop. The second sketch uses an LM35 sensor to read temperature values from analog pin A0 and print them to the serial monitor. The third sketch stores the on/off patterns for the segments of a 7-segment display in an array and uses it to display counting from 10 to 0 on the display. The fourth sketch reads an analog temperature sensor value and writes it simultaneously to three PWM pins to control the brightness of three LEDs based on the temperature.
Отладка в GDB
The document describes debugging a C program with GDB that is causing a segmentation fault. The key steps are:
1. Running the program in GDB shows a segmentation fault occurring in the libc library function atoi().
2. Backtracing reveals the fault occurs when trying to assign an integer to a pointer variable in main().
3. Adding debugging symbols and setting a breakpoint allows inspecting that argv[1] is a null pointer.
4. Passing an argument fixes that fault but causes a new one in the print function when dereferencing the pointer.
5. Further debugging with breakpoints, examining variables and instructions reveals the pointer is being assigned an integer instead of a memory address.
Advanced QUnit - Front-End JavaScript Unit Testing
Code: https://github.com/larsthorup/qunit-demo-advanced
Unit testing front-end JavaScript presents its own unique set of challenges. In this session we will look at number of different techniques to tackle these challenges and make our JavaScript unit tests fast and robust. We plan to cover the following subjects:
* Mocking and spy techniques to avoid dependencies on
- Functions, methods and constructor functions
- Time (new Date())
- Timers (setTimeout, setInterval)
- Ajax requests
- The DOM
- Events
* Structuring tests for reuse and readability
* Testing browser-specific behaviour
* Leak testing
Controlling Arduino With PHP
This document discusses controlling Arduino boards with PHP using an event-driven asynchronous model. It introduces the Arduino board and Firmata protocol. It then describes how to build an event loop system in PHP using event emitters, promises, and non-blocking I/O. Finally, it presents the Carica projects which implement these concepts to interface with Arduino boards from PHP code.

The document discusses various cryptographic concepts and algorithms including:
- Confidentiality, authenticity, and non-repudiation as key security properties.
- Symmetric encryption using keys to encrypt and decrypt data.
- Common symmetric encryption algorithms like RC4 and Salsa20.
- Using pseudorandom number generators and multiple keys for encryption.
- Asymmetric encryption algorithms like RSA, ECC, and key exchange protocols.
- Digital signatures for authentication using hash functions like MD5, RIPEMD, and SHA1.
- The TLS handshake protocol for secure communication between a client and server.
Server
This document contains C code for creating a basic TCP server socket that listens for connections from clients and allows for bidirectional communication by reading from and writing to the client socket file descriptor. The code binds the server socket to port 4020 on IP address 10.180.5.196, accepts an incoming connection, and then enters a loop to continuously read messages from the client and write responses until the client sends the string "bye".
