Driver capabilities trait template. More...

Detailed Description

template<typename Driver>
struct epaper::driver_traits< Driver >

Driver capabilities trait template.

Provides compile-time information about driver capabilities. Must be specialized for each driver implementation.

Required Fields (all must be present in specialization):

max_mode: Highest DisplayMode supported
supports_grayscale: true if Grayscale4 mode available
supports_partial_refresh: true if partial updates supported
supports_power_control: true if sleep()/wake() implemented
supports_wake_from_sleep: true if wake() restores state
max_width: Physical display width in pixels
max_height: Physical display height in pixels

Specialization Example:

// For EPD 2.7" BWR display
template <>
struct driver_traits<EPD27> {
  static constexpr DisplayMode max_mode = DisplayMode::BWR;
  static constexpr bool supports_grayscale = false;
  static constexpr bool supports_partial_refresh = false;
  static constexpr bool supports_power_control = true;
  static constexpr bool supports_wake_from_sleep = true;
  static constexpr std::size_t max_width = 264;
  static constexpr std::size_t max_height = 176;
};

Template Parameters

Driver The driver type to query capabilities for

Note: Base template is intentionally incomplete to force specialization. Attempting to use driver_traits<T> without specialization will fail DriverTraits concept check.
