However I'm worried the software will be a bigger hurdle than expected. I noticed the product page says it has been tested up 190 MBps. Is this project public so we can study it and use it as a foundation? Ideally something like bidirectional data transfer between the DDR and a desktop python program.</p>
Number 6 on DEV-17526 - Alchitry Ft Element BoardNumber 6urn:uuid:817352a4-5e1c-5e95-1f92-1b6c8a1b64b02021-01-08T06:57:15-07:00<p>Some of the "elements" of the descriptions/features were a "bit" confusing to me until I looked at the schematics and saw that the board used an FTDI FT600Q - USB 3.0 to FIFO Bridge: Description "a USB 3.0 200MB/s high speed interface"; Features, "a USB 3.0 200MB/s high speed interface" vs. "200 Mbps* ~ 191 Mbaud*"; Video, "USB 3.0 200MB/s (mega bytes per second) high speed interface". Were you talking about bytes per second or bits per second and what USB standard transfer rate (High Speed/SuperSpeed/etc.)?<p>The FT600Q:
Supports USB 3.0 Super Speed (5Gbps)/USB2.0 High Speed (480Mbps)/USB 2.0 Full Speed (12Mbps) Control/Bulk/Interrupt transfers with 16 kilobytes of buffer(s) and a 16-bit 100MHz parallel FIFO bus. (16-bit * 100MHz = 1600Mbps = 200MB/s) https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT600Q-FT601Q%20IC%20Datasheet.pdf</p></p>
