The ST7701 class initializes the ST7701 LCD controller used by MIPI DSI panels.

Constructors

class display.ST7701

Creates a controller object. Pass it as the controller argument to DSIDisplay() which will invoke ST7701.init() automatically.

init(dc: display.DSIDisplay, dt: Any) → None

Initializes the display.

• dc is the display controller object that must provide bus_write() and bus_read() methods (typically a display.DSIDisplay instance).

• dt is the display timing/configuration argument forwarded by the display controller.

read_id() → bytes

Returns the 3-byte display id read from register 0x04.
