# GPIO Control :id=gpio-control
# GPIO Control {#gpio-control}
QMK has a GPIO control abstraction layer which is microcontroller agnostic. This is done to allow easy access to pin control across different platforms.

The following functions provide basic control of GPIOs and are found in `platforms/<platform>/gpio.h`.

## Advanced Settings :id=advanced-settings
## Advanced Settings {#advanced-settings}
Each microcontroller can have multiple advanced settings regarding its GPIO. This abstraction layer does not limit the use of architecture-specific functions. Advanced users should consult the datasheet of their desired device and include any needed libraries. For AVR, the standard avr/io.h library is used; for STM32, the ChibiOS [PAL library](https://chibios.sourceforge.net/docs3/hal/group___p_a_l.html) is used.
