Fields

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

@brief Reset LCD panel

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @return - ESP_OK on success

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

@brief Initialize LCD panel

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @return - ESP_OK on success

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

@brief Destory LCD panel

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @return - ESP_OK on success

draw_bitmap: Option<unsafe extern "C" fn(_: *mut esp_lcd_panel_t, _: i32, _: i32, _: i32, _: i32, _: *const c_void) -> i32>

@brief Draw bitmap on LCD panel

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @param[in] x_start Start index on x-axis (x_start included) @param[in] y_start Start index on y-axis (y_start included) @param[in] x_end End index on x-axis (x_end not included) @param[in] y_end End index on y-axis (y_end not included) @param[in] color_data RGB color data that will be dumped to the specific window range @return - ESP_OK on success

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

@brief Mirror the LCD panel on specific axis

@note Combine this function with swap_xy, one can realize screen rotatation

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @param[in] x_axis Whether the panel will be mirrored about the x_axis @param[in] y_axis Whether the panel will be mirrored about the y_axis @return - ESP_OK on success - ESP_ERR_NOT_SUPPORTED if this function is not supported by the panel

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

@brief Swap/Exchange x and y axis

@note Combine this function with mirror, one can realize screen rotatation

@param[in] panel LCD panel handle, which is created by other factory API like esp_lcd_new_panel_st7789() @param[in] swap_axes Whether to swap the x and y axis @return - ESP_OK on success - ESP_ERR_NOT_SUPPORTED if this function is not supported by the panel

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
