Hi all,

I'm studying RS232. So I read many posts about serial connection. But it seems, I'm confused at the end. I have few questions about using max232. As I understood so far, max232 is converting the signals coming from pc. So in any case, I have to use it, right? Is there any reason why we do not use coding instead of max232. Does it have any relation with DTE-DTE Connection (handshaking signals) between two PCs?

I'm using pic18f4550, and trying to set up a unidirectional comunication.(pc talks with pic) I want to design my own board, and it is my first time with RS232. So can anyone recommend me a guide for hardware connections?


Best regards...
