---+ The st7789_lvgl display driver

The display driver for the t-watch is extremely simple. It provides a frame buffer for lvgl to draw into and it has a flush method to copy the frame buffer to the device. The driver is written in C and uses gen_mpy.py from lv_bindings to generate the !MicroPython binding automatically.

Its methods are:
   * init(): initializes the st7789 display controller
   * enable_backlight(on_off): enables of disable the LCD backlight
   * flush(): writes the frame buffer to the device
   * send_cmd(cmd): write a command to the st7789
   * send_data(data): send data to the st7789
   * set_orientation(orientation): where orientation can be:
      * PORTRAIT
      * PORTRAIT_INVERTED
      * LANDSCAPE
      * LANDSCAPE_INVERTED
