How to access Port Pin in C.

[tectona]

portpin code in c

Hi ,all

I use MSP430F449 Controller & IAR C compiler.

I want to access IO port as bit operator.
i.g
P4OUT.0 (access Pin- 0 of Port 4)
P4OUT.1 (access Pin - 1 of Port 4)

What is good way to do this in IAR?

Regards

sorrry i dont use IAR but all other C compiler like this:

PORTB.1=0; //Pin1 now 0 o off.i think you must try PORT4.0=1.

i suppose that the information you want in compiler's manual

 

[yogi]

_BV(a) = 1<<a;
#define sbi(port,a) port=port|_BV(a)
#define cbi(port,a) port=port&~_BV(a)

sbi for setting a bit in a port and cbi for clearing a bit in a port
