    Best Way to Read UART String

    ben.satkiewicz

      I am trying to figure out the best way to read a string character by character with the UART. Since it does not have a read string method, I want to write my own.

         

      The method has to return a C string terminated by a null character (the C standard) not delivered by the UART. The number of characters needs to be indefinite. The easiest way to pull this off is to declare a buffer (char array) of a fixed size but this is wasteful. Plus the number of chars may exceed the fixed size.

         

      My knowledge of pointers and dynamic memory allocation in C is not very sound.
