An alternate way which I proposed was to do uint16_t my_int = unaligned_int[0] | unaligned_int[1] << 8 but Anton said it was likely to be slower than a memcpy. I don't know how these unaligned accesses are usually handled in ARM code. I found https://github.com/yura-pakhuchiy/snappy-c/commit/a33077391874b36fb4c430ff9ed5f6e437b65f6f doinng something similar, but that's about it. Christophe
