LED Part Drivers GPIO API Documentation

This page documents the API of the LED Part Drivers GPIO.

An overview of the driver is also available here: main_doc .

Constants and macros

Defines

led_on ( inst ) HAL_GPIO_WritePin(inst##_GPIO_PORT, inst##_PIN, inst##_ACTIVE_STATE)

As opposed to other part drivers (including other LED drivers), there is no led_init() function. The reasoning is that the HAL GPIO initialization already covers all the required settings; cf. `init_state` in the `hal_gpio_config_t` structure.

led_off ( inst ) HAL_GPIO_WritePin(inst##_GPIO_PORT, inst##_PIN, inst##_INACTIVE_STATE)

led_toggle ( inst ) HAL_GPIO_TogglePin(inst##_GPIO_PORT, inst##_PIN)
