Hi Mostafa!

Refer please to this document 0143.TI_3.3V DSP for Digital Motor Control_spra550.pdf. You can find solution there. Also this thread will be useful http://e2e.ti.com/support/microcontrollers/c2000/f/171/t/284365.aspx.

C2000 controllers support 3.3V logic high and not 5V. So if you need to turn/work with 5V logic devices then you'll have to use a 3.3v to 5v converter as follows:
