Hello Mahmut,
What is the board VCC voltage you are using and are you using the internal linear regulator?
Also what is your controller output signal high/low level voltage?
If the VCC voltage is more than 6V using the internal linear regulator, the controll output range should be
0V to 3.3V because VREG voltage in the application is 3.3V.
