Dear libftdi community,
I'm using the libftdi library to communicate with a ftdi chip in ft245
synchronous fifo mode.
I have mostly tested the download (ftdi to host direction), and I have some
great bandwidth : 48.6 MB/s !
(48.6 MB/s comes from dd and dd probably uses 1MB = 10^6 bytes, not 1024*1024)
I would like to share with you my C/C++ and VDHL code.
* https://github.com/RandomReaper/ft2tcp
This sofware connects to a ftdi chip, configure it in synchronous fifo
mode
and make the (bidirectional) stream available on a TCP socket.
* https://github.com/RandomReaper/pim-vhdl
This is my VHDL library, including the ft245 synchronous interface
(hdl/rtl/ft245_sync_if/ft245_sync_if.vhd)
and some examples using it (board/mimas/projects/ft245_counter_to_host
for the bandwidth test).
The hardware has been tested on:
* Xilinx Spartan 6 (XC6SLX9) + ft2232h
* Actel igloo (I forget the model name) + ft2232h
The software has been tested on:
* Ubuntu 16.10 LTS AMD64 bits on a core-i7 (download speed : 48.6 MB/s).
* Windows 7 64 bits (download speed : 38.9 MB/s).
* raspbian on a raspberry pi 2b (download speed : 36.6 MB/s).
* Ubilinux on an intel edison (download speed around 15 MB/s).
Thank you for your great work!
Best regards
Marc
