Maximum rate of ARTY USB-UART

[dcc]

Hi,

Does anyone know ARTY's maximum data rate using the USB-UART?

Thanks.

@dcc,

While I run my Arty UART at 1MBaud, I've run the UART for the Basys-3 up to 4MBaud without problems.  The two share the same circuitry, so 4MBaud should be easily doable without problems.

This may not be the highest speed of the UART.  If you look at the data sheet for the FTDI FT2232H, it suggests that the maximum data rate is 12MBaud (about 1.2MBytes per second).  I've just never tried anything that fast.

@D@nThanks a lot. ~1MB is what I am looking for ... I need to send a long stream of data to ARTY, on FPGA side I guess I just need to fix the clk, on PC side though, I am using tera term VT, do I just increase the Baud?

Thanks again

@dcc,

You will need to up the baud rate within tera term, yes.  You'll also need up adjust the baud rate within your design.  You are probably also going to want something that can collect that data--since most applications that require lots of data to be transferred quickly aren't necessarily transmitting human readable data.

Just some things to think through,

@D@n ... thanks again ... the data is going to a DAC PMOD board ... longer the better, and UART seems the easiest way,  if the rate can be achieved.

@dcc,

Well, okay, but ... you might quickly find that tera term isn't the right tool for the task.

This looks like it describes how to start building serial port comms with Windows, although I haven't read all of it.  It might be a start for your work.

Thanks @D@n ... very helpful.
