pal_gpio_set_high()

LIBRARY_EXPORTS void pal_gpio_set_high

(

const pal_gpio_t *

p_gpio_context

)

Function to transmit and receive a packet.

Function to transmit and receive a packet.

• The API sets the pin high, only if the pin is assigned to a valid GPIO context
  Otherwise the API returns without any failure status

pal_gpio_set_low()

LIBRARY_EXPORTS void pal_gpio_set_low

(

const pal_gpio_t *

p_gpio_context

)

Sets the GPIO pin to Low state.

Sets the GPIO pin to Low state.

• The API set the pin low, only if the pin is assigned to a valid GPIO context.
  Otherwise the API returns without any failure status.
  

Precondition

• None

Note

• None

Parameters

[in]

p_gpio_context

Valid pointer to PAL layer GPIO context
