Dc motor with l293d using pic 16f877a

[adam_adi]

Hi...i'm new with pic16f877a.i need to design the code by using MPLAB IDE v8.70.my schematic will put 2 push button switch.first switch if we press dc motor will run anticlockwise about 360 deg or depend on delay..then when we press switch 2 it will run anticlockwise about 720 deg or depend on delay.i'm beginner in this world.any body can help me.here is my schematic........for lcd it not have problem for me and i already declared lcd using portD...TQ!!

DC motor RPM is high. How will you get exactly 360 deg rotation? How will you know when to stop the motor? You can have angle control with stepper motor.

can dc motor stop by delay?means we put the delay to set how long it rotate...for additional information i'm using hi tech c..hope you can help me.tq!

Do you mean motor runs for 5 seconds at full speed and then stops? I don't know whether dc motor stops instantly or take some time like 10ms, 100ms etc... before stops. But you can use delay to start and stop motor.

yes..but how can i write the code..i'm not have idea to create the code..may u help me please..tq!

i'm try to run in my mplab but it show the error...i'm try to modify ur code it ok but when i put in Proteus look does not any function.motor not rotate..

The dalay function in C18 or Hi Tech C is different. You have to include delay.h file and cally the delay routine that the compiler supports.
