   You can first modify the code according to #515, so that the code can fix the support for DSI driver, then compile, and then your screen will be ST7701. Find the corresponding driver and modify it according to the linked code.

   Parameters such as hsync _ back _ porch, hsync _ pulse _ width, hsync _ front _ porch, vsync _ back _ porch, vsync _ pulse _ width, vsync _ front _ porch, etc. are modified according to the following code (extracted from https://github.com/NickyDark1/esp32_p4_jc4880p433c_bsp):

           .dpi_clk_src = MIPI_DSI_DPI_CLK_SRC_DEFAULT,
           .dpi_clock_freq_mhz = CONFIG_BSP_JC4880P443C_DPI_CLOCK_MHZ,
           .virtual_channel = 0,
           .pixel_format = LCD_COLOR_PIXEL_FORMAT_RGB565,
           .num_fbs = CONFIG_BSP_JC4880P443C_NUM_FB,
           .video_timing = {
               .h_size = CONFIG_BSP_JC4880P443C_LCD_H_RES,
               .v_size = CONFIG_BSP_JC4880P443C_LCD_V_RES,
               .hsync_pulse_width = 12,
               .hsync_back_porch = 42,
               .hsync_front_porch = 42,
               .vsync_pulse_width = 2,
               .vsync_back_porch = 8,
               .vsync_front_porch = 166,
           },
           .flags = { .use_dma2d = true },
       };
           config BSP_JC4880P443C_LCD_H_RES
               int "Horizontal resolution"
               default 480
               help
                   Horizontal resolution of the LCD panel in pixels.
   
           config BSP_JC4880P443C_LCD_V_RES
               int "Vertical resolution"
               default 800
               help
                   Vertical resolution of the LCD panel in pixels.
   
           config BSP_JC4880P443C_DSI_LANE_BITRATE
               int "DSI lane bitrate (Mbps)"
               default 500
               range 200 1000
               help
                   MIPI DSI lane bitrate in Mbps. Higher values support faster refresh rates
                   but may cause signal integrity issues. 500 Mbps is recommended for this panel.
   
           config BSP_JC4880P443C_DPI_CLOCK_MHZ
               int "DPI clock frequency (MHz)"
               default 34
               range 20 100
               help
                   DPI (Display Pixel Interface) clock frequency in MHz.
                   This affects the refresh rate. 34 MHz gives ~60Hz refresh rate.
