New ContributorData transfer between Cyclone V GX Starter Kit and PC
Hello,
FPGA newbie here. I'm trying to create an interface between my PC and my Cyclone V GX Starter Kit (https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=165&No=830&PartNo=2). The dev kit has a USB UART 232 port and I was able to successfully build a UART interface using intel's RS232 IP (streaming Avalon type) just so I have an understanding of how basic interfaces are created. However, the baud rate max (115200 bauds) is too slow as I am looking for 1+ MB data transfer rate. I'd like to ask if anyone has any recommendation as to how I can accomplish this goal using the ports on my device?
What I'd like to ideally do is to be able to send a 16 bit data stream, such as a PC generated Sine wave using Labview software to the FPGA and to send 16 bit data back from the FPGA to the PC. It'd be best if I can do this as simply as possible (e.g. not have to use NIOSII etc.). Any advice would be appreciated. Thanks.
PI'm commonly using 920 kbaud UART interface between PC and FPGA for test and configuration tools because it's the fasted standard rate supported bei PCs or e.g Bluetooth adapters. Non-standard RX oversampling factors, e.g. 13 instead of 8 or 16 are helpful to operate the UART with usual clock frequencies like 24 or 48 MHz.
FrankP.S. Forgot to mention that FT232R supports up to 3M if you need higher speed, but it needs special programming on the PC side to set the non-standard rate. FTDI has suggestions how to achieve it.
