hello, I am new to this mailing list and haven't used lwIP before. I
hope you can get me some advice for my project.
I ran the httpserver_raw demo for lwIP on my Zynq SoC. I'd like to
transfer video data from my FPGA to the PC @ 1GbE, point-2-point,
single client, bare metal. I'd also like to send some simple
control commands from PC to SoC on this link.
I am planning on scripting a server-client transmission entirely
on PC with python to develop my client software. There are many
examples available.
httpserver_raw uses simple instructions in the format POST +
"cmd" + "<instruction_name>". I researched and found out
that I can do the same using my frame buffer instead of a file
system.
One thing I could not find out is if I need to take care about
packet sizes or not. Can I send any size in one tcp_send() or do I
need to split it to fit MTU? Are there existing applications I should use or should I make my own software? Also any tipps or advice would be appreciated.
thank you,
Markus |
