本文详细介绍了如何使用nrf_gpio_pin_write函数来控制GPIO引脚的状态，包括设置引脚为输出模式和写入具体值的方法。同时，提供了配置引脚作为输出的具体函数nrf_gpio_cfg_output的用法说明。

/**
* @brief Function for writing a value to a GPIO pin.
*
* Note that the pin must be configured as an output for this
* function to have any effect.
*
* @param pin_number Specifies the pin number to write.
*
* @param value Specifies the value to be written to the pin.
* @arg 0 Clears the pin.
* @arg >=1 Sets the pin.
*/
__STATIC_INLINE void nrf_gpio_pin_write(uint32_t pin_number, uint32_t value);

实例：

nrf_gpio_pin_write(m_board_led_list[led_idx], LEDS_ACTIVE_STATE ? 0 : 1);

/**
* @brief Function for configuring the given GPIO pin number as output, hiding inner details.
* This function can be used to configure a pin as simple output with gate driving GPIO_PIN_CNF_DRIVE_S0S1 (normal cases).
*
* @param pin_number Specifies the pin number.
*
* @note Sense capability on the pin is disabled and input is disconnected from the

buffer as the pins are configured as output.
*/
__STATIC_INLINE void nrf_gpio_cfg_output(uint32_t pin_number);

实例

nrf_gpio_cfg_output(m_board_led_list[i]);
