> My current problem is that a simple math equation doesn't seem to work. I=
t is:
>         int16_t encper =3D (encval/255) * 100;
>=20

try:
int32 tmp =3D encval;
tmp =3D (tmp * 100) / 255;
encper =3D tmp;
When you make division first, you loose resolution, so any value <255 will
be 0. =20
if encval has range 0-655, then you do not need to use int32 temp variable.

Hope this helps,
