Function Documentation

void gpio_clear ( uint32_t  port,
uint16_t  pin 
)

Clear a gpio output to low level.

Definition at line 37 of file gpio_arch.c.

uint16_t gpio_get ( uint32_t  gpioport,
uint16_t  gpios 
)

Read a gpio value.

Definition at line 39 of file gpio_arch.c.

void gpio_set ( uint32_t  port,
uint16_t  pin 
)

Set a gpio output to high level.

Definition at line 35 of file gpio_arch.c.

void gpio_setup_input ( uint32_t  port,
uint16_t  gpios 
)

Setup one or more pins of the given GPIO port as inputs.

Parameters
[in]port
[in]gpiosIf multiple pins are to be changed, use logical OR '|' to separate them.

Definition at line 33 of file gpio_arch.c.

void gpio_setup_output ( uint32_t  port,
uint16_t  gpios 
)

Setup one or more pins of the given GPIO port as outputs.

Parameters
[in]port
[in]gpiosIf multiple pins are to be changed, use logical OR '|' to separate them.
