PID code in C++ language

Hi every1

Can someone please send me the code in C++ for PID control? The code should be like that when it is run , the window should ask for Kp, Ki , Kd and sample time? and then generates the pwm output. I will use a USB daq card for to control the motor speed.

Any help will be greatly appreciated.

Regards
Simon

People are not going to do your work for you. And there is no generic code that fits all.

I am not asking anyone to write code for me but if anyone has previouly done this task then it can be a source of guidance for me?
