Hi all!

I am using the lpcxpresso 11u14 and i'm trying to concatenet two uint8_t, in order to create an uint16_t.

I have these two variables in an array: (data[0] = uint8_t) (data[1] = uint8_t). Actually i want to convert "data" in an uint16_t.

Anyone knows how could i do it ?

thank you very much!

You mean something like that

First method:
<code>
uint16_t locsh_Val= *((uint16_t*)data);
</code>

Second method:
<code>
typedef union _t_MyUnion
{
uint16_t Data16;
uint8_t Data[2];
} t_MyUnion;

t_MyUnion loc_Union;
loc_Union.Data[0]=0xAA;
loc_Union.Data[1]=0x55;

uint16_t locsh_Val=loc_Union.Data16; //locsh_Val == 0x55AA
</code>
