### Usage
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
typedef <GPIOA, 9> somePin; //Define pin PA9 as somePin
|
|
|
|
```
|
|
|
|
After that you can
|
|
|
|
```cpp
|
|
|
|
//Read from that pin
|
|
|
|
somePin::mode(Mode::INPUT);
|
|
|
|
int value = somePin::value();
|
|
|
|
|
|
|
|
//Set the pin's value
|
|
|
|
somePin::mode(Mode::OUTPUT);
|
|
|
|
somePin::high();
|
|
|
|
somePin::low();
|
|
|
|
```
|
|
|
|
|
|
|
|
All the possible pin modes and speeds can be found in the
|
|
|
|
gpio_impl.h inside `libs/miosix-kernel/miosix/arch/<your_arch>/common/interfaces-impl`.
