Pin 28 is PC6
Pin 29 is PC7
DDRC is already config'd as output

This is where you make your changes

#define FWD 0xAA
#define REV 0x55
#define R 0x22
#define L 0x88
#define CW 0x99
#define CCW 0x66
#define STOP 0x00
#define B 0xFF

For example:

in move()

PORTC = R;

writes a '1' to PC1 and PC5 (pins 23 & 27) since 0x22 is 0010 0010

Just remap according to you schematic (or modified schematic)

 

ok sir can you pls tell what change i should do to make the motor run for the pins 22 23 24 25 in port c...
pls help me...

 

You have defined all ports as inputs, thus there is not output.

yes sir can you pls tell wat changes should i make to get the output according to the schematic....

 

Write:

DDRC=0b00001111;

DDRD=0b00110000;

 

thanks for the reply sir... i hav a new problem... how should i configure the cksel and the sut fuses for the 16mhz crystal oscillator

 

Read the data sheet of your uC.

 

Do you have a screen in your CodeVisionAVR that looks like this? If so then check to make sure that the JTAGEN fuse is not selected.

You should be able to consult the User's Manual for your C compiler to answer your questions on what software features are available to manage the fuses on your microcontroller. All of the recent generation of microcontrollers have these internal fuses to permit the flexibility that makes them so useful.

can you please tell what changes i should do in the pgm to make the motor to run please help me sir.....

Have you confirmed that your JTAG fuse is set to disable the JTAG feature?
