Hi to all.
I'm an Arduino newbie, so forgive the eventual stupidity of my question, very important for my project, about Ethernet Shield and TCP sockets...
I've been not able to find docs about this subject.
I need to load "bit-oriented" data from my PC to put in serial-to-parallel shift registers, then read parallel-to-serial shift registers in bytes and resend them back to the pc.
I already have all the electronics and logic to move data from/to shifts but,
"there exist a possibility to send/receive RAW data (SOCK_RAW) instead of ASCII chars with Ethernet Library - and/or in general with ethernet shield?"
In other words, since I need to receive and send raw bytes instead of strings of ASCII chars, how to do this? With which libraries and commands?
And, if not, how to convert ASCII values from/to BYTE values?
Example: "FF"=>B11111111 ?
Thanks in advance to all
Federico (il papa buono)
