Detailed Description

GPIO driver requirements validator.

Validates that GPIO drivers provide required functionality using the method detection system. This is the core GPIO contract enforcement for Sound Byte Libs drivers.

GPIO Driver Contract

Every Sound Byte Libs GPIO driver MUST implement these methods:

• set_mode(const GpioHandle&, PinMode) - Configure pin mode
• write(const GpioHandle&, bool) - Write logical value (handles active_low)
• read(const GpioHandle&) -> bool - Read logical value (handles active_low)
• toggle(const GpioHandle&) - Toggle pin output

Validation Usage

Add validation at the bottom of driver gpio.hpp:

#include <sbl/validation/gpio_requirements.hpp>
static_assert(sbl::validation::gpio_driver_valid<sbl::driver::Gpio>,
              "GPIO driver missing required methods");
