One Pin Control Motor Stop, CW, CCW
Posted: Tue Feb 05, 2013 12:12 pm
This is concept how to control a motor to moving Clock wise, Counter Clock wise and Stop just using single pin from PIC.
Output High: CW
Output Low: CCW
High impedance / configure as input pin: Stop

the program: using hi-tech c compliler
void main()
{
TRISB=0b11100001;
PORTB=0b11100000;
OPTION_REG=0b01111111;
while(1)
{
if(!RB5)
{ TRISB0=0;
RB0=1; }
else if(!RB6)
{ TRISB0=0;
RB0=0; }
else if(!RB7)
{ TRISB0=1;
RB0=0; }
}
