    Setting up the Linksys EA9300 Max-Stream AC4000 Tri-Band Wi-Fi Router Setting up the Linksys EA9300 Max-Stream AC4000 Tri-Band Wi-Fi Router is made easy using the Smart Setup wizard which is embedded in the router's firmware and is available even if the router does not have an internet connection or the router is on factory default settings. Before you begin: Make sure you have a working internet connection. Power on your modem and connect an ethernet cable from the modem to the internet port of the router. NOTE: If you are replacing an existing router, make sure to disconnect and remove the old one. Connect the power adapter to the router and turn it ON. Wait until the Linksys logo light is solid. Step 1: Connect a wireless computer, tablet or smartphone to the default Wi-Fi network of your router. The wireless credentials are located on a label at the bottom of the device. NOTE: If you need to set up the router using a hardwired computer, connect your computer to one of the ethernet ports at the back of the router. Step 2: Launch a supported web browser and enter “linksyssmartwifi.com” in the Address bar then press [Enter]. NOTE: You can also enter “http://192.168.1.1” or “myrouter.local”. Step 3: Check the box beside I have read and accepted the License Terms for using this software. Then click Next to proceed. NOTE: Open the link to know the license terms and other information.

  • Converting a Microcontroller Lab from the Freescale S12 to the Atmel Atmega32 Processor
    ASEE-NMWSC2013-0025 Converting a Microcontroller Lab From The Freescale S12 to the Atmel ATmega32 Processor Christopher R. Carroll University of Minnesota Duluth [email protected] Abstract During the summer of 2013, the laboratory supporting the microcontroller course at the University of Minnesota Duluth was completely re-implemented. For the last several years, the processor that has been used was the Freescale S12, a popular 16-bit microcontroller with a long ancestral history 1. The recent popularity of the Atmel AVR series of microcontrollers, as used in the Arduino microcomputers, for example, has prompted a change in the lab to use Atmel’s ATmega32 microcontroller, an 8-bit member of the AVR family of microcontrollers 2,3 . The new processor has a fundamentally different architecture than that used in the past, but the input/output resources available are much the same. This paper addresses issues that will be faced in the conversion when the course is taught with the new lab hardware for the first time in the Fall. At the very fundamental level, the S12 and ATmega32 differ in architecture. The S12 is a Princeton architecture computer (single memory for both program and data), while the ATmega32 is a Harvard architecture computer (separate program and data memories). The S12 is clearly a CISC machine (Complex Instruction Set Computer) while the ATmega32 is clearly a RISC machine (Reduced Instruction Set Computer). These differences will affect how the microcontroller course is taught when it is offered in the Fall using this new lab. Fortunately, however, the collection of input/output devices in the AVR microcontrollers mimics closely what is found in the S12, so that many of the existing lab exercises will be used again with only minor tweaking.

    Network speed between a given system adapter and the network Router is determined by the slowest network device. If the Router is an N Router, then your adapter mode is set for G. The problem is likely your Intel AGN Adapter settings - it's Wireless Mode is likely set to G, B/G, or A/B/G, but the N Mode setting probably isn't Enabled, which overrides the other Wireless Modes. Prior to the procedures below, go to Linksys Support, look up your Router, then download the latest firmware update. If it's the same as what you have, then download that. Linksys Support Standard Procedure for any Linksys Router problem with speed or signal begins with flashing the firmware prior to adjusting any other settings. I've added settings for your Router to match your adapter since I have the same hardware. You can look for your Router's firmware update at Linksys Support Enter your Model # and go from there to get the firmware update. The following assumes you have a Linksys Single Band N Router; though these settings are from my Linksys WRT600N Dual-Band, the Admin Panel is the same, except for the extra 5ghz Band setup on mine. Just in case, I've also added the 5ghz settings. With these settings and the AGN or my Linksys WUSB600N DBN Adapter, I average better than 200mbps+, usually around 240 or 260mbps. The settings for the AGN adapter after these settings are matched for the Router settings. On your Router: Access the Router Admin Panel & Wireless Settings from your Browser - http://192.168.1.1/BasicWirelessSettings.htm 1.

Abstract: Nowadays, microcontrollers are commonly used in many fields of industrial applications previously dominated by other devices. Their strengths such as: processing power, low cost, and small sizes enable them to become substitutes for industrial PLC controllers, analog electronic circuits, and many more. In first part of this article an overview of the Atmel AVR microprocessor family can be found, alongside with many scientific and industrial applications. Second part of this article contains a detailed description of two implementations of ATmega644PA microprocessor. First one is a controller with PID regulation that supports a DC motor driver. Second one is a differential equation solver with 4-th order Runge-Kutta method implemented. It is used for solving a torsion pendulum dynamics. Finally, some general conclusions regarding the two presented implementations are made. Keywords: Atmel, AVR, ATmega, microcontroller, torsion pendulum, PID control, DC motor, PWM control 1.
