need C code of using PID in microcontroller

[ala]

i'm student and i have a project about implementation of PID for DC TO DC convertor using microcontroller and i wwill use PWM as out of the microcontroller to control the DC TO DC convertor .... ineed any one has C code for this case or he can help me in my project will send to me full documentation about this program
thanks and regards

If you plan to use this method you will need to run your pic's clock very fast and use componants with large time constant.

I posted some code yesterday to control a heater but the code could also work for any other process that has feedback. Just change the variables to fit your aplication. You should also know what a PID controler really is before you try to use one.

Hi!

I tried to click the link to access the codes, but it has been removed.
