PxOUT all outputs at once?

[chibiace 46]

hi is it possible to set say BIT0-3 as on and 4-5 as off and 6-7 as on like: 11110011.

such as this for arduino:

DDRD = B11111110; // sets Arduino pins 1 to 7 as outputs, pin 0 as input from http://www.arduino.cc/en/Reference/PortManipulation

 

thanks in advance. :clap:

You can do that.

 

PxOUT = 11110011;

You can define binary type, see attached include file.

Then you could do P1OUT = b11110011;

 

binary.h.zip

you can also do PxOUT |= BIT1 | BIT2 | BIT3 | BIT4 | BIT5 | BIT6 | BIT7 | BIT8

or calculate the hexadecimal value out of your binary value and set it like PxOUT = 0xFF

 

i relly dont understand why the compiler doesnt understand binary-format out of stock :crazy: especially programming MCU's this format is often used

That question is best addressed to the ISO C Working Group .

 

GCC does understand binary literals, though.
