Re: problem in write PID program in C !!!

ok thans everybody.<p>but my problem now is i want to generate a PWM signal by using 8255 programmable peripheral interface card. i short out0 and Gate1 so that out1 can output PWM. but i use CRO to look at it. But just a constant voltage appears. my program is follows:<p>#include<stdio.h> #include<...

Re: problem in writing PID with C program

hi
thans everybody. Yes. i have a A/D converter that convert the sensors data into digital form. so the problem is how to write PID with C progam?

hi thank you Chris Foley but i am using 8255 I/O card that contains 8254,8255 mirco-controller.<p> ref PWM distance output sharpGP2D12 ------->+ >--PID -->car -->IR sensor | data | |----<----------------- | here is the flow chart<p>so how can i write PID with C program in the above chart. i am soso

Re: problem in write PID program in C !!!

hi my flow chart is like this: input is sensor data via PID controller and then via vechicles<p> PWM ref distance output --->------+ >----PID ----->car ---->IR sensor | | |----<-------------------| the above figure is my flow chart so how can i write it in C program?? i am soso

problem in writing PID with C program

hi, i am writing a PID program that can control the car to have lane keeping function.
i am using six Sharp GP2D12 IR sensors to collect the data then by using C program to write PID.
so my problem now is how to write this one??
