Honored ContributorCyclone III FPGA development kit USB communication
Hello,
Did any body used FTDI chip in Cyclone III dk (EP3C120F780C7N) for PC communication. Altera website claims USB2.0 communication in their link (http://www.altera.com/products/devkits/altera/kit-cyc3.html). But the kit did not shipped with any reference designs. Please provide any suggestions or help if you had worked on USB-PC communication for Cyclone III dk Thanks in advance, Trinath13 Replies
Altera_ForumYou have a list of third party IPs here:
http://www.altera.com/products/ip/ip-index.jsp There are a few USB cores. I expect that none of them are free, but you may be able to get an evaluation version.- Altera_Forum
Thank you very much!
I'm a newbie in FPGA usb communication. My application is using FPGA for high speed data acquisition, and the data will be transfered to a laptop by USB communication. Which one of the IP list is preferred? - Altera_Forum
I don't know these cores, but it seems that the main difference between them is the supported USB protocol version (1.1, 2.0 or 3.0) and whenever the core can act as a host or a device.
If you have the option to make your own extension board, something with an FTDI chip could be simpler. Or as an alternative in theory it should be possible to reconfigure the MAX II CPLD to use the existing USB port for something else, but I don't think it is documentet anywhere... and of course you would loose the embedded USB blaster function.
