MikroC code for controlling motor

[NadaF]

hi, i need a help plz, i'm computer science and i don't know very well about electronics and my graduation project is about auto drive system , now i have in my car 2 motors and i need to control it using pic16F877A but i don't know how to control it !! plz anyone help me in coding it i don't have enough time

i have made a flow chart for my project i just need a C code for controlling motors

hii
i think problem is so easy to use pic16f--
make that for each motor View attachment circuits design.rar

thank you very much,
can you help me,, now i'm using HC-SR04 ping sensor,, when i write the code i couldn't know how to get the time from timer in pic 16f877a ,, i'm using MikroC language plzz help me if you can

thank you for help but i need code not the circuit for controlling DC motor using MikroC language

This is my code to control Motor by using SONY tv remote control. Since I am using two dc motors I can turn it left or right. Hope this might be useful for you.
Use pic 16f877a at 4MHZ frequency.
