In c, how is uint8_t structure_member[4] different than uint32_t structure_member in regards to structure padding? The same technique works with other variable types, you need to be aware of how many bytes in each type of variable and be aware that a union overlaps different variable into the same physical memory while a struct puts variables into contiguous locations in physical memory. Thanks for the code. Both of the values have to be passed into uint8_t array[4]; The array format uint8_t array[4] = { 0x00, 0x00, //value of a should come here (hex format) 0x00, 0x00} 0x00 represents the hex format.
