enum nrf_gpiote_outinit_t |
|
static |
Function for configuring GPIOTE channel as input, automatically clearing an event that appears in some cases under configuration.
Note that when configuring the channel as input an event might be triggered. Care of disabling interrupts for that channel is left to the user.
channel_number | specifies the GPIOTE channel [0:3] to configure as an input channel. |
pin_number | specifies the pin number [0:30] to use in the GPIOTE channel. |
polarity | specifies the desired polarity in the output GPIOTE channel. |
|
static |
Function for configuring GPIOTE channel as output, setting the properly desired output level.
channel_number | specifies the GPIOTE channel [0:3] to configure as an output channel. |
pin_number | specifies the pin number [0:30] to use in the GPIOTE channel. |
polarity | specifies the desired polarity in the output GPIOTE channel. |
initial_value | specifies the initial value of the GPIOTE channel input after the channel configuration. |
|
static |
Function for unconfiguring GPIOTE channel.
Note that when unconfiguring the channel, the pin is configured as GPIO PIN_CNF configuration.
channel_number | specifies the GPIOTE channel [0:3] to unconfigure. |
