struct syntax

[future]

Hello,

I am planning to use a struct to take care of portb status.

The reason is that I can set all pins at the same time.

like:

#byte portb = 0xf81

struct {
int1 pin0;
int1 pin1;
int1 pin2;
int1 pin3;
int1 pin4;
int1 pin5;
int1 pin6;
int1 pin7;
} port;

port.pin0 = 1;
port.pin3 = 1;

portb = port; // bits 0 and 3 goes high

Is this construct correct and/or is there a better way?

Thank you.

How about this:

Basicaly they are the same thing, your suggestion won't work how I need...

In main(), sensors are read and data processed.. depending on the results it sets bits.

In the end of all processing, the byte is copied to portb setting all bits at the same time.

What I asked was ideas on how to write this in C... using structs the code looks nice.
