Enumeration Type Documentation

gpio_function_select_t

enum gpio_function_select_t

Possible function values for gpio_io_ctrl_t::function_select.

Enumerator
FUNCTION_SELECT_SPI	connect pin to the SPI peripheral (MISO/MOSI/SCK depends on pin)
FUNCTION_SELECT_UART	connect pin to the UART peripheral (TXD/RXD depends on pin)
FUNCTION_SELECT_I2C	connect pin to the I2C peripheral (SCL/SDA depends on pin)
FUNCTION_SELECT_PWM	connect pin to the timer for PWM (channel depends on pin)
FUNCTION_SELECT_SIO	use pin as vanilla GPIO
FUNCTION_SELECT_PIO0	connect pin to the first PIO peripheral
FUNCTION_SELECT_PIO1	connect pin to the second PIO peripheral
FUNCTION_SELECT_CLOCK	connect pin to the timer (depending on pin: external clock, clock output, or not supported)
FUNCTION_SELECT_USB	connect pin to the USB peripheral (function depends on pin)
FUNCTION_SELECT_NONE	Reset value, pin unconnected.

gpio_mode_t

enum gpio_mode_t

gpio_mode_t but with the addition of PIO pins

Enumerator
GPIO_IN	configure as input without pull resistor
GPIO_IN_PD	configure as input with pull-down resistor
GPIO_IN_PU	configure as input with pull-up resistor
GPIO_OUT	configure as output in push-pull mode
GPIO_OD	configure as output in open-drain mode without pull resistor
GPIO_OD_PU	configure as output in open-drain mode with pull resistor enabled
GPIO_PIO0	configure pin for PIO usage
