Hi,

I am trying to toggle GPIO25 (PIN_21) on cc3200 but it doing nothing. I wrote program

unsigned char g_ucPIN21gpio;
unsigned int ulPort = 3;

#define PIN21gpio 25

GPIO_IF_GetPortNPin(PIN21gpio, &ulPort, &g_ucPIN21gpio);

GPIO_IF_Set(PIN21gpio, ulPort, g_ucPIN21gpio, 0);
MAP_UtilsDelay(8000000);

GPIO_IF_Set(PIN21gpio, ulPort, g_ucPIN21gpio, 1);
MAP_UtilsDelay(8000000);

I have used Pin Mux tool to create mux.h and .c file

void PinMuxConfig(void)
{
//
// Enable Peripheral Clocks
//
PRCMPeripheralClkEnable(PRCM_GPIOA3, PRCM_RUN_MODE_CLK);

//
// Configure PIN_21 for GPIO Output
//
PinTypeGPIO(PIN_21, PIN_MODE_0, false);
GPIODirModeSet(GPIOA3_BASE, 0x2, GPIO_DIR_MODE_OUT);
}

can anyone of you suggest me what is wrong here. Thank You in advance.

I'm using this code to switch pin 15 on anf off. Maybe it helps:

pinmux_config.c

...

/* GPIO */
	//
    // Configure PIN_15 for GPIO Output
    //
	MAP_PinTypeGPIO(PIN_15, PIN_MODE_0, false);
	MAP_GPIODirModeSet(GPIOA2_BASE, 0x40, GPIO_DIR_MODE_OUT);

...


main.c

...

MAP_GPIOPinWrite(GPIOA2_BASE,GPIO_PIN_6,GPIO_PIN_6); //Set  Pin 15 to 1

MAP_GPIOPinWrite(GPIOA2_BASE,GPIO_PIN_6,0); //Set Pin 15 to 0


...

Greetings

Why do you use GPIO_PIN_6 when you are trying to toggle PIN_15?

Hi James,

Please see www.ti.com/.../swru367 at chapter 5.

This GPIO_PIN_6 defines mask for pin. From gpio.h:

#define GPIO_PIN_0 0x00000001 // GPIO pin 0
#define GPIO_PIN_1 0x00000002 // GPIO pin 1
#define GPIO_PIN_2 0x00000004 // GPIO pin 2
#define GPIO_PIN_3 0x00000008 // GPIO pin 3
#define GPIO_PIN_4 0x00000010 // GPIO pin 4
#define GPIO_PIN_5 0x00000020 // GPIO pin 5
#define GPIO_PIN_6 0x00000040 // GPIO pin 6
#define GPIO_PIN_7 0x00000080 // GPIO pin 7

GPIO_PIN_6 = 0x40 = bit mask for GPIOA2 peripheral.
