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.
