Member Data Documentation

◆ busy_gpio

gpio idfxx::epaper::uc8179::config::busy_gpio = gpio::nc()

GPIO wired to the panel's BUSY output (required).

The UC8179 drives BUSY low while an operation is in progress.

Definition at line 87 of file uc8179.hpp.

◆ busy_timeout

std::chrono::milliseconds idfxx::epaper::uc8179::config::busy_timeout {30'000}

Maximum time to wait for the BUSY line to release.

Full refreshes of large panels take several seconds on some glasses and temperatures.

Definition at line 91 of file uc8179.hpp.

◆ height

size_t idfxx::epaper::uc8179::config::height = 480

Panel height in pixels (gates). The controller drives up to 600.

Definition at line 78 of file uc8179.hpp.

◆ reset_gpio

gpio idfxx::epaper::uc8179::config::reset_gpio = gpio::nc()

GPIO wired to the panel's reset line, or gpio::nc() if not wired.

Required for wake, and strongly recommended in general: the driver hardware-resets the controller when switching between refresh waveforms so each mode starts from a known register state.

Definition at line 84 of file uc8179.hpp.

◆ width

size_t idfxx::epaper::uc8179::config::width = 800

Panel width in pixels (sources).

Must be a multiple of 8; the controller drives up to 800. Defaults match the 7.5" 800x480 GDEY075T7 glass.
