Hi, I am have got FT245 RL and i need to get the data tranmitted from an FPGA.The data is going to be an 8 bit data.I am doing the conversion using FPGA itself.I now want to read the data from the FPGA.I am new to FTDI and i am struck.Can some one please help me out?Aslo please tell me as to which 2 pins should i short to check the loopback .
I am not familiar with a FT245 RL can you please clarify what that is and an overview of how it works? It would also very very helpful if you can give me more details about your application and what you are trying to do
What is the communication protocol between the FPGA and the usb Controller, is it a USB standard? Please refer to www.ni.com/ipnet This is a collection of pre-made FPGA functions for different applications. You may be able to find some source code you could implemet there.
I have a little problem, maybe someone can help me.
I want to communicate between FPGA and USB using Labview 8.2.
I'm using ALTERA Cyclone II FPGA and
FT245BL USB from FTDI and I tried to test the write-read routine
(labview example) from FTDI website (see the link below): http://www.ftdichip.com/Projects/CodeExamples/LabVIEW.htm The
write function is working (the bytes are written in the paralel
port).The function FT_GetQueueStatus returns a parameter Bytes Waiting
which is zero, so this means there are no bytes to read from FTDI
device.My question is:
Is there any protocol already implemented in Labiew and a website from
where I can download it to do the communication between FPGA and USB? I have the VHDL code downloaded from ALTERA website and I installed all the
required drivers related to my FTDI device model. The drivers were downloaded from
website and also the D2XX _functions_7.0 for Labview.
Had the same problem.I checked the FTDI seperately like made a daughter card and used a FPGA starter kit.The communication was proper.So i concluded that the problem was on the bus.
What you can do first is download the virtual comm port driver.This will enable you to check the communication via hyper terminal and also you can use visa serial port communication readily available in labVIEW.Can you send me the VHDL code so that i can let you know If there is any need for modification
