Hello sir,

I'm currently using with F28335. and i have problem about floating value storege in memory.

I have variable, float a = 68.123,

and i want to use it's hex value(0x42883EF9) which is stored at some memory location.

anyone help me for this?

I have try this code:

asm(" MMOVIZ MR0,#68.123 ");

asm(" MMOVXI MR0,#68.123 ");

I'm getting error that [E0000] CLA instructions cannot apper with non-CLA instructions in the same location.

What can i do for getting Hex value of float value?

It sounds like you have mixed CLA code within C28x code which is not allowed. They have to be in separate sections.

Thanks for help.

I just want to use Hex value of float which is stored in memory address. Is it possible to get that hex value and stored that hex in two 16bit int without using CLA?

If not than how this is possible using CLA instruction?

You can use a union

typedef{

float32 f;

int32 i;

}float32_t;

float32_t some_value = 68.3;

Then you can access the hex element through "some_value.i"
