◆ gpio_port_config_lock()

void gpio_port_config_lock ( uint32_t  gpioport,
uint16_t  gpios 
)

Lock the Configuration of a Group of Pins.

The configuration of one or more pins of the given GPIO port is locked. There is no mechanism to unlock these via software. Unlocking occurs at the next reset.

Parameters
[in]gpioportUnsigned int32. Port identifier GPIO Port IDs
[in]gpiosUnsigned int16. Pin identifiers GPIO Pin Identifiers If multiple pins are to be locked, use bitwise OR '|' to separate them.

◆ gpio_port_read()

uint16_t gpio_port_read ( uint32_t  gpioport)

Read from a Port.

Read the current value of the given GPIO port. Only the lower 16 bits contain valid pin data.

Parameters
[in]gpioportUnsigned int32. Port identifier GPIO Port IDs
Returns
Unsigned int16. The value held in the specified GPIO port.

◆ gpio_port_write()

void gpio_port_write ( uint32_t  gpioport,
uint16_t  data

Write to a Port.

Write a value to the given GPIO port.

Parameters

Set a Group of Pins Atomic.

Set one or more pins of the given GPIO port to 1 in an atomic operation.

Parameters
[in]gpioportUnsigned int32. Port identifier GPIO Port IDs
[in]gpiosUnsigned int16. Pin identifiers GPIO Pin Identifiers If multiple pins are to be changed, use bitwise OR '|' to separate them.

◆ gpio_set_af()

void gpio_set_af ( uint32_t  gpioport,
uint8_t  alt_func_num,
uint16_t  gpios 
)

Set GPIO Alternate Function Selection.

Set the alternate function mapping number for each pin. Most pins have alternate functions associated with them. When set to AF mode, a pin may be used for one of its allocated alternate functions selected by the number given here. To determine the number to be used for the desired function refer to the individual datasheet for the particular device. A table is given under the Pin Selection chapter.

Note that a number of pins may be set but only with a single AF number. In practice this would rarely be useful as each pin is likely to require a different number.

Parameters
[in]gpioportUnsigned int32. Port identifier GPIO Port IDs
[in]alt_func_numUnsigned int8. Pin alternate function number Alternate Function Pin Selection
[in]gpiosUnsigned int16. Pin identifiers GPIO Pin Identifiers If multiple pins are to be set, use bitwise OR '|' to separate them.

void gpio_set_output_options ( uint32_t  gpioport,
uint8_t  otype,
uint8_t  speed,

Set GPIO Output Options.

When the pin is set to output mode, this sets the configuration (analog/digital and open drain/push pull) and speed, for a set of GPIO pins on a given GPIO port.

Parameters
[in]gpioportUnsigned int32. Port identifier GPIO Port IDs
[in]otypeUnsigned int8. Pin output type GPIO Output Pin Driver Type
[in]speedUnsigned int8. Pin speed GPIO Output Pin Speed

void gpio_toggle ( uint32_t  gpioport,
uint16_t  gpios

Toggle a Group of Pins.

Toggle one or more pins of the given GPIO port. The toggling is not atomic, but the non-toggled pins are not affected.

Parameters
