Hi all,

I'm using Broadcom's sample code almost exactly now, and before I was trying to run a linear resonant actuator (through a transistor) with my TAG dev board, now I'm just using a multimeter, and no matter what I do, I can't change the configuration of the pins and pull them high/low. I have gpio_configurePin(port,pin,GPIO_OUTPUT_ENABLE,GPIO_PIN_OUTPUT_HIGH/LOW) and gpio_setPinOutput(port,pin,GPIO_OUTPUT_HIGH/LOW), and nothing. Any ideas?

Hello Zoltan,

Let me start you off on a few Forum posts:

Can someone tutor me on GPIO usage?

GPIO Flag Magic Numbers in bleprofile.h

Let me try to find more examples

Thanks

Could you point to which GPIO's you are trying to  toggle ?

There is also an excellent new article here: GPIO usage in WICED Smart SDK written by one of our power users zhaohua

You may find this helpful, in addition toBCM2073XS GPIO Basics

Did you remember to set up the GPIO pin here?

const BLE_PROFILE_GPIO_CFG contact_exchg_gpio_cfg =

{

    /*.gpio_pin =*/

    {

        GPIO_PIN_WP,      // This need to be used to enable/disable NVRAM write protect

        GPIO_PIN_BUTTON,  // Button GPIO is configured to trigger either direction of interrupt

        GPIO_PIN_LED,     // LED GPIO, optional to provide visual effects

        GPIO_PIN_BATTERY, // Battery monitoring GPIO. When it is lower than particular level, it will give notification to the application

        GPIO_PIN_BUZZER,  // Buzzer GPIO, optional to provide audio effects

        -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1 // other GPIOs are not used

    },

    /*.gpio_flag =*/

    {

        GPIO_SETTINGS_WP,

        GPIO_SETTINGS_BUTTON | GPIO_BOTHEDGE_INT,

        GPIO_SETTINGS_LED,

        GPIO_SETTINGS_BATTERY,

        GPIO_SETTINGS_BUZZER,

        0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0

    }

};
