Hi, I'm beginner in coding, I'm using STM32F407G Discovery with HAL library and I want to implement PI controller.

I tried the code mentioned in

http://stm32f4-discovery.net/2014/11/project-03-stm32f4xx-pid-controller/

 but it works only for proportional regulator for ki=0.

Maybe it's problem of setting time, I don't know how to fix it.

I need help please

The relevant

page is quite thorough.  There's some pseudocode near the bottom that will give you a starting point, and there is no shortage of references, links & tutorials.

The

used to contain such control algorithm implementations, amongst others. Both integer and single-precision floating point.
