Detailed Description

Function Documentation

◆ gpio_hal_arch_no_port_pin_cfg_get()

gpio_hal_pin_cfg_t gpio_hal_arch_no_port_pin_cfg_get ( gpio_hal_pin_t  pin)

Read the configuration of a GPIO pin.

Parameters
pinThe GPIO pin number (0...GPIO_HAL_PIN_COUNT - 1)
Returns
An OR mask of GPIO_HAL_PIN_CFG_xyz

It is the platform developer's responsibility to provide an implementation.

The implementation can be provided as a global symbol, an inline function or a function-like macro, as described above.

Note
Code should not call this function directly. Use GPIO manipulation macros instead.

◆ gpio_hal_arch_no_port_pin_cfg_set()

void gpio_hal_arch_no_port_pin_cfg_set ( gpio_hal_pin_t  pin,
gpio_hal_pin_cfg_t  cfg 
)

Configure a gpio pin.

Parameters
pinThe GPIO pin number (0...GPIO_HAL_PIN_COUNT - 1)
cfgThe configuration

cfg is an OR mask of GPIO_HAL_PIN_CFG_xyz

The implementation of this function also has to make sure that pin is configured as software-controlled GPIO.

It is the platform developer's responsibility to provide an implementation.

The implementation can be provided as a global symbol, an inline function or a function-like macro, as described above.

Note
Code should not call this function directly. Use GPIO manipulation macros instead.

◆ gpio_hal_arch_no_port_read_pin()

uint8_t gpio_hal_arch_no_port_read_pin ( gpio_hal_pin_t  pin)

Read a GPIO pin.

Parameters
pinThe GPIO pin number (0...GPIO_HAL_PIN_COUNT - 1)
Return values
0The pin is logical low
1The pin is logical high

It is the platform developer's responsibility to provide an implementation.

The implementation can be provided as a global symbol, an inline function or a function-like macro, as described above.

Note
Code should not call this function directly. Use GPIO manipulation macros instead.

◆ gpio_hal_arch_no_port_read_pins()

gpio_hal_pin_mask_t gpio_hal_arch_no_port_read_pins ( gpio_hal_pin_mask_t  pins)

Read multiple pins.

Parameters
pinsAn ORd pin mask of the pins to read
Return values
AnORd mask of the pins that are high

If the position of the pin in pins is set and the pin is logical high then the position of the pin in the return value will be set. For example, if you pass 0x09 as the value of pins and the return value is 0x08 then pin 3 is logical high and pin 0 is logical low.

It is the platform developer's responsibility to provide an implementation.

The implementation can be provided as a global symbol, an inline function or a function-like macro, as described above.
