Hey guys, I'm delving into programming this chip, I am very new and I'm referencing the pwm_tones example, but im using the wiced device configurator. I 've connected my LED as per my illustration. here

GPIO_HEADERS_JAREDDLC.jpg

with the following code:

// TurquoiseBicuspid Constants

#define TURQUOISEBICUSPID_LED1_GPIO            (26)

// TurquoiseBicuspid Function Prototypes

static void turquoisebicuspid_blink_led1(void);

here is my function:

void turquoisebicuspid_interrupt_handler(UINT8 value)

{

    // On press.

    if(value & 1)

    {

        ble_trace0("turquoisebicuspid_interrupt_handler()");

        turquoisebicuspid_blink_led1();

    }

}

void turquoisebicuspid_blink_led1(void)

{

    ble_trace0("turquoisebicuspid_blink_led1()");

    gpio_configurePin((TURQUOISEBICUSPID_LED1_GPIO) / 16, (TURQUOISEBICUSPID_LED1_GPIO) % 16, GPIO_OUTPUT_ENABLE, 0);

    gpio_setPinOutput((TURQUOISEBICUSPID_LED1_GPIO) / 16, (TURQUOISEBICUSPID_LED1_GPIO) % 16, 1);

}

I see the trace:

23:29:12 - turquoisebicuspid_interrupt_handler()

23:29:12 - turquoisebicuspid_blink_led1()

However I wasn't sure If I am using the setPinOutput correctly as my LED does not turn on. I would like to set this pin to HIGH, similar to arduino's


digitalWrite(TURQUOISEBICUSPID_LED1_GPIO, HIGH)

analogWrite(TURQUOISEBICUSPID_LED1_GPIO, 255);


Thanks in advanced. I'm calling it a night for today. I'll check tomorrow.

Hello jareddlc,

Sorry for the late response, but I just noticed you had another question here.

The TAG003 LED was de-populated by default at our factory.

If you can solder one to the pins you should be able to use it.

Thanks.

JT

How do you want ot use the LED? Active high/low? gpio_setPinOutput is the right way to drive it high or low (none of the GPIOs can output an analog signal). If you are using the pwm_tones sample app, it configures P26 as a PWM channel. Did you remove all such code from the sample app? If you toggle the GPIO by setting output to 0 and 1 alternatively, say every 1s, can you see the GPIO toggling on an oscilloscope?

I don't own an oscilloscope, and I haven't got to delay timing yet. I'll look into it tonight. Do you know what timing I should be using to wait/delay every 1000ms? just for the sake of testing this really quick, if not, i'll look at some more examples to figure it out.

I generated code using the new wiced device configurator. Im just referencing pwm_tones to figure out how they used buttons and pwm. thanks

You don't want to wait for 1s. Use timers instead. The pwm_tones sample app already registers for a 1s timer callback. Just implement your toggle logic in tones_timeout()

Here is how i have setup my gpio, according to the picture above, which I made from the docs. At this point im starting to this I made it incorrectly. As my code is not working.

the function I am trying to get to work is on line: turq 372 of the gist. Does anyone have any experience with turning on an LED with the dev kit? I would really appreciate it, if you can show me some code, as I am not having any luck.
