Rotation not supported

[FxIII]

I'm using this library with the DSTIKE ESP32 Watch DevKit TFT here. It works like a charm (put python into a watch was my secret dream). Alas the screen is rotated 90° cw, I added a function to set rotation :

STATIC mp_obj_t st7789_ST7789_set_rotation(mp_obj_t self_in, mp_obj_t value) {
    st7789_ST7789_obj_t *self = MP_OBJ_TO_PTR(self_in);
    mp_int_t m = mp_obj_get_int(value);
    uint8_t madctl[] = {ST7789_MADCTL_RGB};
    switch (m) {
    case 0:
      madctl[0] =  ST7789_MADCTL_MX | ST7789_MADCTL_MY | ST7789_MADCTL_RGB ;
      write_cmd(self, ST7789_MADCTL, madctl, 1);
      break;
    case 1:
      madctl[0] =  ST7789_MADCTL_MY | ST7789_MADCTL_MV | ST7789_MADCTL_RGB ;
      write_cmd(self, ST7789_MADCTL, madctl, 1);
      break;
    case 2:
      madctl[0] =  ST7789_MADCTL_RGB ;
      write_cmd(self, ST7789_MADCTL, madctl, 1);
      break;
    case 3:
      madctl[0] =  ST7789_MADCTL_MX | ST7789_MADCTL_MV | ST7789_MADCTL_RGB ;
      write_cmd(self, ST7789_MADCTL, madctl, 1);
      break;
    default:
      break;
    }
    return mp_const_none;
}
MP_DEFINE_CONST_FUN_OBJ_2(st7789_ST7789_set_rotation_obj, st7789_ST7789_set_rotation);

But when setting in mode 1 there is like an offset of 80 pixels (the fill function leaves a vertical band on the right)

No clues of what next (I'm remapping everything in sw right now). Any Idea?

Look at this fork https://github.com/russhughes/st7789_mpy

rotation argument and method ST7789.rotation(r)
