Xilinx is one of the largest FPGA/CPLDmanufacturers. Its design and development software is constantly upgraded and has developed from the Foundation series to the current ISE 5.x series. ISE ( Integr...
:Cry::Cry: I have been working on this for a few days. I want to realize the basic functions, lock the phase and frequency. I will be satisfied if the input is about 250HZ and it can be locked. Please...
Actual combat! In this section, we will explain the functions of the SCAN user driver subroutine for the EASY-M0806R PLC. Through the previous explanation, you should know that SCAN is a program calle...
I am now using FPGA to make an ICX274CCD driver with AD9949. The problem is the dual sampling SHP SHD in AD9949.By default, SHP = 0X24 SHD = 0X00, but I always feel that it is not right. I think SHP =...
