UART WaveformFig 2. Continued fig 1. WaveformMethod Two: Use the middle modeThe code is as follows, using the Nios II HAL mode to read and write the information.This mode uses the ISR

Software developmentReferring to experiment two (LED), this experiment and experiment two (LED) difference is that the system clock from 50M to become 100M. Run the result, output hello from Nios ii! in the Debug window, and the four LED lights on the board flow display, indicating the test was successful! This experiment confirmed that the board support Operation frequency is high enough to reach 100M.Experiment Code /** "Hell

More and more people are using Nios II. After all, NIOS II is the most versatile soft core processor in the world.NIOS eds are usually loaded together when the Quartus is loaded. Usually we use the template to build the project when we are using it.In many cases, after installing quartus, we were able to run Nios EDS, Eclipse, but when the project was established

Previously thought to learn FPGA will be very useful, beginning to contact with FPGA, try to use Verliog to write peripheral IP, because of their own skill is still shallow, write out mostly not too stable, dare not use. Later think why not Nios II directly run soft core, the realization of peripheral communication will be very convenient, safe and reliable, so take the development Board to learn the operation of the water lamp. LED lamp program runni

Symbol ' xx_base ' COULD not being resolved resolved in NIOS II EcliplseIn Nios II, system.h defines the # define Xxx_base 0x00000010, but when you write a program, call Iord (xxx_base) or IOWR (xxx_base), always prompt for type ' xxxx_base ' Could not be resolved error, recompile no, re-generate BSP also not.In the Nios II development, added a PIO after, also re

You use Altera's megafunction to generate the "divider" Wizard, now you will see like that follows: // Megafunction Wizard: % lpm_divide %// Generation: Standard// Version: wm1.0// Module: lpm_divide // ================================================ ======================================// File name: div31.v// Megafunction name (s ):// Lpm_divide//// Simulation library files (s ):// LPM// ================================================ ======================================//*************

Solution:First, you need to convert the. BDF schematic file to a standard description file supported by third-party EDA tools such as OpenGL. In Quartus, keep *. BDF is in the active window status. Run the [file]/[Create/update]/[Create HDL design file for current file] command. In the pop-up window, select the file type as "maid, output *. V top-level file. Below is a specific solution from: http://www.wlu.ca/science/physcomp/nznotinas/altera_reference/Quartus_ModelSim_schematic.shtml query:Qua

, its configuration data is stored in SRAM and must be re-downloaded when power is added. In an experimental system, a computer or a controller is usually used for debugging, so PS can be used. In the practical system, in most cases the FPGA must be actively guided to configure the operation process, when the FPGA will actively from the peripheral dedicated storage chip to obtain configuration data, and this chip in the FPGA configuration information is designed by the ordinary programmer to the

Recently, the great god of end China, a faint bean, published the blog fpga r D path (25)-pin, I just got a new book titled deep understanding of Altera FPGA application design. Here we will organize the knowledge of the two. I/O feature notes for the cyclone IV device will be added later. In the previous article, the pin introduction in Altera FPGA has provided a brief and comprehensive description of the

Tribute to the originalHttp://blog.sina.com.cn/s/blog_6276db0e0101ary8.htmlTo compare Xilinx and Altera FPGAs, it is necessary to understand the structure of two giant FPGA, because of their respective interests, the two FPGA structure is different, the parameters are different, but can be unified to the LUT (look-up-table) lookup table.Take the example of Altera's Cyclone II series Ep2c35, as well as the xc3s500e of the Xilinx spartan-3e series.
