P2 LED CC2530DK Minikit Target Board

Hi Leonardo,
the code snippet YK sent out shows the right way and approach to control external devices through GPIO
In general, you can do the following

#define BIT0 0x01
#define BIT1 0x02
#define BIT2 0x04
#define BIT3 0x08
#define BIT4 0x10
#define BIT5 0x20
#define BIT6 0x40
#define BIT7 0x40

/* For instance, let's configure P2.0 and P2.3 as LED*/
/* Fir select the desired pins as GPIO*/
P2SEL &= ~(BIT0 | BIT3);
/* Then select the pins as output*/
P2DIR |= (BIT0 | BIT3);
/* Set the desired pins as high to turn LED on*/
P2OUT|= (BIT0 | BIT3);

/* Set the desired pins as low to turn LED off*/
P2OUT&= ~(BIT0 | BIT3);

Please also note that in P2 port P2.1 and P2.2 provide the debug interface to the debugger, and you should avoid modifying settings for those pins.
Please also understand we point people to documents as we want to provide tangible artifacts and through collateral resources to our statements. For the specific thing you would like to achieve, which is basically controlling an external LED through a GPIO, I would recommend you use as a reference the following:
www.ti.com/.../swru191f.pdf, chapter 7
Also, please note Z-Stack SDK contains LED driver for CC2530/SRF05 platform with example code you can look at: \Components\hal\target\CC2530EB\hal_board_cfg.h (for macros and definition
Components\hal\target\CC2530EB\hal_led.c for high level LED driver

This is a community forum and people are trying to help each other out by providing code examples, recommendations, suggestions, help with debugging and we are inspired by this sense of community, at the basis of which there is a sense of collaboration and respect for all members.
Though I can understand sometimes there can be things which don't go right from the first line of code dropped, the best way to continue to get help and making this forum useful is to keep a respectful and positive attitude that foster collaboration.

Thanks,

After much times... My problem is sorved.

on my file: msp430x22x4.h, in the standard bits have so much defines incluing BIT0, BIT1 ... BITF, ok.

On my example_basic_comms_router_application_afzdo.c in the main function I wrote the follows line codes:

P2SEL = 0x00;
P2DIR = 0xFF;
P2OUT = 0x00; // Start turn all off

delayMs(3000); //wait 3 seconds off

while(1){

// HIGH
P2OUT |= (BIT2 | BIT3 | BIT4);//if want put only BIT2 or (BIT2 | BIT4)

delayMs(1000);

// LOW
P2OUT &= ~(BIT2 | BIT3 | BIT4);
//P2OUT &= ~(BIT3 | BIT4);// 2nd pin ever high

delayMs(1000);

}

Thanks for all

It's not working only because of reason of not having delay after turning off the LED.

Try this it will work.

while(1){

P2OUT|=0x01; // output P2.0 as high

delayMs(1000);

P2OUT|=0x00; // output P2.0 as low <- dont works

delayMs(1000);
}
