Data mismatch with structure pointer Posted on May 18, 2017 at 16:09Hello, I recently migrated from 8 bit processors and something that has always worked for me is showing some unexpected behavior. Clearly I am missing something very obvious to you 32 bit guys // define a structure somewhere in header filetypedef struct{ char first[2]; char second[2]; char third; char fourth; uint8_t fifth; uint16_t sixth; uint8_t seventh; char eight;} my_struct;// create a fielduint8_t my_field[11]={0x2D, 0x43, 0x30, 0x30, 0x52, 0x75, 0x01, 0x0D, 0x00, 0x01, 0x21}; my_struct *p_to_mystruct=(void *)my_field;now if I look into contents of p_to_mystruct i get this:p_to_mystruct->first[0] = 0x2Dp_to_mystruct->first[1] = 0x43p_to_mystruct->second[0] = 0x30p_to_mystruct->second[1] = 0x30p_to_mystruct->third = 0x52p_to_mystruct->fourth = 0x75p_to_mystruct->fifth = 0x01p_to_mystruct->sixth = 0x0100 // NOTICE A PROBLEM HEREp_to_mystruct->seventh = 0x21 // ALSO WRONGp_to_mystruct->eight = 0xb5 /
