Use of bit fields

[Akutabi]

Hi,

Is it possible to use bit fields with CCS ?

In C ANSI, bit fields are used like this :

struct {
short x:5, y:4, z:7;
}data;

struct data my_data;

my_data.x = ....
my_data.y = ....
my_data.z = ....

So, is it possible to to do the same with CCS ?

Thanks,

Yes. Bit fields are part of standard C (not just ANSI C), and CCS follows the 'norm' with this. However there is a restriction. Since the default data type is an 8 bit integer, the field 'boundaries' have to fit inside this. As shown, it'll fail, since a 5 bit field, plus a 4 bit field, and a 7 bit field will not fit into an 8 bit field.
