First tutorial of all. Or it is better to say tutorial summary, since I will only give links of useful tutorials in this post. The first topic to be posted is Serial Communication. Serial Communication has been used widely in embedded system. A lot of sensors or modules used serial as their main communication to exchange data. Serials only used a few wire to communicate, which is the advantage of these communication. The drawback it had is the serial com is slower compared to parallel communication. But in the embedded application where I/O limitation sometimes could become a problem, serial communication is definitely one of the option.
Well, cut to the chase. As I surf the Internet for good tutorial about Serial Communication, I stumbled upon tutorial from Sparkfun which is very easy to read and explain enough basic about serials. It explain about the difference about parallel and serial, wiring between two serial devices, the basic data packet used in serials, etc. Next, after understanding the basics, advanced user can go to explanation from tldp.org for further details about serials and serial ports used in PC. And for *nix implementation, advanced user can go to explanation and example code at digilander.libero.it about Serial Programming Guide for POSIX Operating Systems.
Thats all. The all the three links are given below.
