  • Hi prabhudurai,

    still havent gone through your code, but had a quick look. I saw this below code in your init_gpio() function

    NRF_GPIO->PIN_CNF[6] = (GPIO_PIN_CNF_DRIVE_H0D1 << GPIO_PIN_CNF_DRIVE_Pos);

    This is wrong as you are setting every other bits to '0' and only setting the drive strength. With this the pin will be configured as input. To do this correctly, you need to do this below

    NRF_GPIO->PIN_CNF[6] &= ~(GPIO_PIN_CNF_DRIVE_Msk); // reset drive setting
    NRF_GPIO->PIN_CNF[6] |= (GPIO_PIN_CNF_DRIVE_H0D1 << GPIO_PIN_CNF_DRIVE_Pos); // set to high drive
    

    you need to do this for pin settings 7 also.
