passing a sbit to a function

[SteveH]

Hi,

I have the following bit defined

sbit MY_BIT at GPIOA_ODR.B0

Is it possible to pass this to a function, possibly like this ? - ditto for an IDR bit

MyFunction(MY_BIT) ;

void MyFunction(unsigned long mySbit) { // probably unsigned long is wrong type ?
...
mySbit = 1 ;
...
}

Any help on this appreciated - it would save repeating a large code block six times that is only different by two sbits.

a bit has no adress
perhaps pass the port and the bit number

Thanks for the reply.

After much testing, head scratching and every syntax I could think of I've given up on a direct solution. I've ended up just passing an index to the function that I can use in a switch statement to get to the correct sbits in a short a space as possible.

Hi,

The sbit type cannot be used for argument lists, and function-return values.
