◆ 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.
