How to use ports in a loop

[osmanandac]

I want to make like a following code
// the port definitons
RA3=my_ports(0)
RB2=my_ports(1)
RA1=my_ports(2)
RB7=my_ports(3)
RB0=my_ports(4)
Rxx=my_ports(x)
...

//then use in loop
....
for(i=0;i<10;i++)
{
my_ports(i)=1;
.....
my_ports(i)=0;
.....
}

I don't understand what you are trying to do. If you post a reply please include which chip and compiler you are using.

I think he's trying to ask for a dynamic way of bit setting

 

[Pommie]

If that is what he is asking then, in BoostC, you can do,

volatile int Ports @PORTA;
int PortBits[16]={
    0x8000,0x4000,0x2000,0x1000,
    0x0800,0x0400,0x0200,0x0100,
    0x0080,0x0040,0x0020,0x0010,
    0x0008,0x0004,0x0002,0x0001
};

void SetPort(char index){
    Ports=PortBits[index];
}

With the above, SetPort(0) will set bit 7 of PortB. Swapping the values in the table will change the order.

Yes this is my solution

If that is what he is asking then, in BoostC, you can do,

volatile int Ports @PORTA;
int PortBits[16]={
    0x8000,0x4000,0x2000,0x1000,
    0x0800,0x0400,0x0200,0x0100,
    0x0080,0x0040,0x0020,0x0010,
    0x0008,0x0004,0x0002,0x0001
};

void SetPort(char index){
    Ports=PortBits[index];
}

With the above, SetPort(0) will set bit 7 of PortB. Swapping the values in the table will change the order.

Thank you Mike for reply, i am using 16F877 and 16F628.
You replied solution for only one port. Can i define PORTA, PORTB, PORTC ports are together in ports structure?
