Hi
I want to communicate with the 16F877 over RS232 port.
Most of the users suggest MAX232 . I ve found some other people who is facing the MC and GSM use different ICs such as ST3237EB or SP232EEN level converters.
what differences are there between them ? one more question.
I see many 5 input and 3 output ports for ST3237EB and SP232EEN .
why is that for input and outputs more than 1 ?
Thanks.
