Enumeration Type Documentation

PinLevel

enum class sbl::core::hal::gpio::PinLevel

strong

Digital logic levels.

Standard digital logic levels for GPIO operations.

Enumerator
Low	Logic low (0V, GND)
High	Logic high (Vdd, 3.3V typically)

PinMode

enum class sbl::core::hal::gpio::PinMode

strong

GPIO pin modes.

Standard pin configuration modes supported across ARM Cortex-M platforms. Platform implementations map these to hardware-specific configurations.

Enumerator
Input	Digital input (high impedance)
Output	Digital output (push-pull)
InputPullup	Digital input with internal pull-up resistor.
InputPulldown	Digital input with internal pull-down resistor.
OpenDrain	Open-drain output (requires external pull-up)
Analog	Analog input (for ADC)
