The latter gives a warning with gcc "-Wconversion" as well. Although I
was long opposing that warning, it's hard to argue your head out of it
if your company's software already had a few incidents with it. For
control code, it is definitively possible to get "-Wconversion"-free;
for computational code, it's some more work but possible (e.g. make a
'sample_add' inline function that does the casting, and use that).

What I find more annoying is that MISRA finds this

     uint32_t MASK = UINT32_C(1) << 17;

objectionable. '1', no matter how spelled, has type 'char' for MISRA,
and cannot be shifted by 17 bits.
