Honored ContributorHi Dave
To answer your questions: We will be adding a few more interfaces to this code and it just made sense to minimize the HW if possible. We do have one of those little usb spi cables and ive used that in the past to talk to another dut. not sure of the maker, but i do remember downloading the FTDI drivers. it worked well, but again, we are just looking to do much more. this is me getting my feet wet with fpga. this should be "easy," but being so new, it adds to the learning curve. Ok, on to the last 24 hours: I realize that what is instantiated in my qsys is the jtag_uart. Ive read that i cant use putty etc to talk to this jtag_uart. I can only use nios2-terminal (which is corrupt on my 14.1 install...14.0 works ok) or Altera Monitor (which doesnt work on 14.1) or i can actually use the "nios2 console" window inside the Eclipse IDE (didnt realize that when i was trying to use system console. so i closed the console and nios2 console tabs in eclipse and went back to sys console and was able to use bytesteam to send some chars, but its not full duplex...cant see the response from nios printfs) So the big questions i have: After further reading, i see the jtag_uart is not the same thing as the usb-uart you use. I see a uart (rs232) in qsys. I see that you configure the baud rate inside qsys to 115k bits. Not exactly the 1MBps speed. How would i create and use the usb-uart interface? What tools do you use to interface with usb-uart? Putty? How do i use this to move massive amounts of data through the usb-uart? one character at a time or is code to take entire files or big chunks and push it through? Again, Dave, thank you for all your help!
