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. The source code of Elektor usb daq card in C language for usb communication MUST ALSO CONTAIN this PID CODE but how , has anyone implemented this before?
Any help will be greatly appreciated.
Regards
Simon

Hallo
I am also trying to build a interface of the ELEKTOR USB DAQ card on LABVIEW. I think I’m using the same VI’s for communication as you all do. I downloaded the VI’s I attach whit this post. The problem is that I don’t know what I have to sent to the pic and what I get back. I suspect that I have to sent hexadecimal codes to the controller using theUSBWrite and have to read with the USBRead. But which codes? An on which inputs. I never used USB communication and I don’t know what the inputs and outputs of this vi’s mean. Can someone explain it to me? Or is there someone who can make a loop back test or something like that for me.
