XAPP1042-利用GPIO實現(xiàn)以太網(wǎng)PHY寄存器訪問

The XPS Ethernetlite peripheral does not provide any mechanism to access the Ethernet PHYregisters. These registers are used to configure auto negotiation parameters and to obtain PHYstatus. This application note provides reference systems and associated software to accessPHY registers by connecting the serial management bus signals MDC and MDIO to GPIOswhich the software controls directly.

遠程配置Nios II處理器應(yīng)用筆記

通過以太網(wǎng)遠程配置Nios II 處理器應(yīng)用筆記 Firmware in embedded hardware systems is frequently updated over the Ethernet. For embedded systems that comprise a discrete microprocessor and the devices it controls, the firmware is the software image run by the microprocessor. When the embedded system includes an FPGA, firmware updates include updates of the hardware image on the FPGA. If the FPGA includes a Nios® II soft processor, you can upgrade both the Nios II processor—as part of the FPGA image—and the software that the Nios II processor runs, in a single remote configuration session.

XAPP806 -決定DDR反饋時鐘的最佳DCM相移

This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory is controlled by a controller that attaches to either the OPB or PLB and is used inan embedded microprocessor application. This reference system also uses a DCM that isconfigured so that the phase of its output clock can be changed while the system is running anda GPIO core that controls that phase shift. The GPIO output is controlled by a softwareapplication that can be run on a PowerPC® 405 or Microblaze™ microprocessor.

This article is a very simple introduction writing a Windows Form application for the Microsoft.NET

This article is a very simple introduction writing a Windows Form application for the Microsoft.NET framework using C#. The sample application demonstrates how to create and layout controls on a simple form and the handling of mouse click events. The application displays a form showing attributes of a file. This form is similar to the properties dialog box of a file (Right click on a file and Click on Properties menu item). Since attributes of a file will be shown, the sample will show how to use File IO operations in .NET framework.

Introduction to GPS ToolKit Pro 1.0 GPS ToolKit Pro is an ActiveX object that makes it easy to add

Introduction to GPS ToolKit Pro 1.0 GPS ToolKit Pro is an ActiveX object that makes it easy to add GPS support to any Visual Basic, Visual C++, Delphi, Excel, or scripting project that supports ActiveX controls. GPS data (including lat/lon, speed, course, altitude, and dozens of other datasets) can be accessed through GPS ToolKit s properties, and GPS ToolKit s multithreaded event-based architecture notifies your application when data has been updated, saving you from having to write messy polling routines.

Displaying large amounts of technical data in a chart can be a frustrating task. You can find tons of charting controls with fancy effects and useless features, but when it comes to displaying many curves at once, independently scaled on different axes, most of them fail.
