I want to create a generic display driver based on a 7219 IC using an 80C32. Suppose I need to prime the library code with the port locations that will serve as clock and data. I wnat this to be generic to promote reuse.

Basically what I want to do is something like this.

APPLICATION 1:
void main(void){
Init7219(P1^3, P1^4);
DispData(0x03);
}

APPLICATION 2:
void main(void){
Init7219(P1^6, P1^2);
DispData(0x03);
}

LIBRARY:
static serclk;
static serdata;
Init7219(clk, data){
//assing clk & data to use
serclk = clk;
serdata = data;
}
DispData(uchar dat){
//clock out data...assembler
mov a, dat
rlc a
mov serdata, c
setb clk
clrb clk
etc....
}

Any ideas would be much appreciated.

Thanks,
Rich
