Hi! Everyone,

In Project Zero example code i had called GPIO_write( GPIOCC26XX_DIO_01 , 1 ); in project_zero.c but this function is not setting the pin high after configuring the GPIO in CC2640R2_LAUNCHXL.c

please tell me where i went wrong.

Regards,

Vijay Rakesh.

Hello,

It looks like you added 3 more GPIOS to the table. Go to the CC2640R2_LAUNCHXL.h and find the:

typedef enum CC2640R2_LAUNCHXL_GPIOName {
    CC2640R2_LAUNCHXL_GPIO_S1 = 0,
    CC2640R2_LAUNCHXL_GPIO_S2,
    CC2640R2_LAUNCHXL_GPIO_LED_GREEN,
    CC2640R2_LAUNCHXL_GPIO_LED_RED,
    CC2640R2_LAUNCHXL_GPIO_SPI_FLASH_CS,

    CC2640R2_LAUNCHXL_GPIOCOUNT
} CC2640R2_LAUNCHXL_GPIOName;

and add three new GPIO Defs, like so:

typedef enum CC2640R2_LAUNCHXL_GPIOName {
    CC2640R2_LAUNCHXL_GPIO_S1 = 0,
    CC2640R2_LAUNCHXL_GPIO_S2,
    CC2640R2_LAUNCHXL_GPIO_LED_GREEN,
    CC2640R2_LAUNCHXL_GPIO_LED_RED,
    CC2640R2_LAUNCHXL_DIO_0,
    CC2640R2_LAUNCHXL_DIO_12,
    CC2640R2_LAUNCHXL_DIO_15,
    CC2640R2_LAUNCHXL_GPIO_SPI_FLASH_CS,

    CC2640R2_LAUNCHXL_GPIOCOUNT
} CC2640R2_LAUNCHXL_GPIOName;

and when you use the GPIO_Write Function use this:

GPIO_write(CC2640R2_LAUNCHXL_DIO_0, 1);
