From uint16 to Q_format

Dario Detomaso

Hi ,

I have a variable declared as uint16.

To use this variable in a control algorithm, I have to convert this in format Q17 .

This format in simulink matches fixdt (1,32,17).

HowI should do?

I'm using simulink and code coposer studio

Hi Dario,

Is this control algorithm a library meant for simulink or CCS ?

You can simply use this instruction _IQ(your value). This will convert the variable from u16 to _iq.

But you need to look that your u16 value does not get beyond the maximum value IQ17 can posses. The maximum value is (+/- 16384).

If it is in range you can simply the use the instruction.
