help pls!!!!

[josak]

i am doing project in robotics ....i am new to embedded field as well as hardware.
i need to know how to use the mother board for storing sensor data and camera output???
whether we need to install an operating system in the mother board for controlling these functions.....:roll:

Depending on wha you use. Microcontroller or microprocessor? Microcontroller is like PIC and AVR, ranges from 8 bit to 32 bit. Microprocessor is like Atom or higher range of AVR families.

k john ....thanks for replying.....
i am using pic controller in this same project for motor control......
i need to store the sensor outputs for a while so i need mother board for that.......
now i need to know how can i use the mother board...
do u have any materials regarding this!!!!!!!!1

 

[john blue]

You need to be more specific.

 

[josak]

dude can i control both clockwise and anticlockwise rotation of a dc motor (not stepper) using pic ......

 

[john blue]

yes. You just need additional one h bridge

Simple Hbridge code for pic16F877A:


#include <pic.h>
#include <htc.h>


#define sw1 RE0
#define sw2 RE1


void int_io(void);

void init_io(){

__CONFIG(0x3F3A);

TRISB = 0b00000000;
TRISE = 0b00000011;

PCFG3 = 0;
PCFG2 = 1;
PCFG1 = 1;
PCFG0 = 1;

PORTB = 0xff;


}

void main(){

init_io();

if (!sw1 && !sw2){
RB0 = 1;
RB1 = 1;
RB2 = 1;
RB3 = 1;
}
else if (!sw1){
RB0 = 1;
RB1 = 1;
RB2 = 0;
RB3 = 0;
}
else if (!sw2){
RB0 = 0;
RB1 = 0;
RB2 = 1;
RB3 = 1;

}
