Enumeration Type Documentation

◆ gpio_flank_t

enum gpio_flank_t

Enumerator

GPIO_RISING	emit interrupt on rising flank
GPIO_BOTH	emit interrupt on both flanks

Definition at line 92 of file periph_cpu.h.

◆ gpio_mode_t

enum gpio_mode_t

Available pin modes.

Generally, a pin can be configured to be input or output. In output mode, a pin can further be put into push-pull or open drain configuration. Though this is supported by most platforms, this is not always the case, so driver implementations may return an error code if a mode is not supported.
