Single-byte alignment of arrays of triple-byte structs?

Hi,



I need to store a set of triple-byte structs in a contiguous RAM space. E.g.:





struct triplebyte

{

   uint8_t a;

   uint8_t b;

   uint8_t c;

};



struct triplebyte data[ 50 ];





I need data[ 1 ].a to be located in the byte after data[ 0 ].c. I've tried various combinations of #pragmas and attribute((aligned(1))) but although I can get a,b and c to be next to each other, I can't get each triple next to each other.



How can this be done with this compiler?



Thanks!
