§set_gap: Option<unsafe extern "C" fn(_: *mut esp_lcd_panel_t, _: i32, _: i32) -> i32>

@brief Set extra gap in x and y axis

@note The gap is only used for calculating the real coordinates.

§invert_color: Option<unsafe extern "C" fn(_: *mut esp_lcd_panel_t, _: bool) -> i32>

@brief Invert the color (bit 1 -> 0 for color data line, and vice versa)

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @param[in] invert_color_data Whether to invert the color data @return - ESP_OK on success

§disp_on_off: Option<unsafe extern "C" fn(_: *mut esp_lcd_panel_t, _: bool) -> i32>

@brief Turn on or off the display

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @param[in] on_off True to turns on display, False to turns off display @return - ESP_OK on success - ESP_ERR_NOT_SUPPORTED if this function is not supported by the panel
