# ESP LCD ST7703 [![Component Registry](https://components.espressif.com/components/espressif/esp_lcd_st7703/badge.svg)](https://components.espressif.com/components/espressif/esp_lcd_st7703) Implementation of the ST7703 LCD controller with esp_lcd component. | LCD controller | Communication interface | Component name | Link to datasheet | | :------------: | :---------------------: | :------------: | :-----------------------------------------------------------------------------------: | | ST7703 | MIPI-DSI | esp_lcd_st7703 | [PDF](https://dl.espressif.com/AE/esp-iot-solution/ST7703DA-H3_DS_V0.01_20200819.pdf) | **Note**: MIPI-DSI interface only supports ESP-IDF v5.3 and above versions. For more information on LCD, please refer to the [LCD documentation](https://docs.espressif.com/projects/esp-iot-solution/en/latest/display/lcd/index.html). ## Add to project Packages from this repository are uploaded to [Espressif's component service](https://components.espressif.com/). You can add them to your project via `idf.py add-dependancy`, e.g. ``` idf.py add-dependency "espressif/esp_lcd_st7703" ``` Alternatively, you can create `idf_component.yml`. More is in [Espressif's documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html). ## Example use ```c /** * Uncomment these line if use custom initialization commands. * The array should be declared as static const and positioned outside the function. */ // static const st7703_lcd_init_cmd_t lcd_init_cmds[] = { // {cmd, { data }, data_size, delay_ms} // {0xE0, (uint8_t []){0x00}, 1, 0}, // {0xE1, (uint8_t []){0x93}, 1, 0}, // {0xE2, (uint8_t []){0x65}, 1, 0}, // {0xE3, (uint8_t []){0xF8}, 1, 0}, // ... // }; ESP_LOGI(TAG, "MIPI DSI PHY Powered on"); esp_ldo_channel_handle_t ldo_mipi_phy = NULL; esp_ldo_channel_config_t ldo_mipi_phy_config = { .chan_id = 3, .voltage_mv = 2500, }; ESP_ERROR_CHECK(esp_ldo_acquire_channel(&ldo_mipi_phy_config, &ldo_mipi_phy)); ESP_LOGI(TAG, "Initialize MIPI DSI bus"); esp_lcd_dsi_bus_handle_t mipi_dsi_bus = NULL; esp_lcd_dsi_bus_config_t bus_config = ST7703_PANEL_BUS_DSI_2CH_CONFIG(); ESP_ERROR_CHECK(esp_lcd_new_dsi_bus(&bus_config, &mipi_dsi_bus)); ESP_LOGI(TAG, "Install panel IO"); esp_lcd_panel_io_handle_t mipi_dbi_io = NULL; esp_lcd_dbi_io_config_t dbi_config = ST7703_PANEL_IO_DBI_CONFIG(); ESP_ERROR_CHECK(esp_lcd_new_panel_io_dbi(mipi_dsi_bus, &dbi_config, &mipi_dbi_io)); ESP_LOGI(TAG, "Install ST7703 panel driver"); esp_lcd_panel_handle_t panel_handle = NULL; const esp_lcd_dpi_panel_config_t dpi_config = ST7703_720_1280_PANEL_60HZ_DPI_CONFIG(EXAMPLE_MIPI_DPI_PX_FORMAT); st7703_vendor_config_t vendor_config = { .mipi_config = { .dsi_bus = mipi_dsi_bus, .dpi_config = &dpi_config, }, }; const esp_lcd_panel_dev_config_t panel_config = { .reset_gpio_num = EXAMPLE_LCD_IO_RST, // Set to -1 if not use .rgb_ele_order = LCD_RGB_ELEMENT_ORDER_RGB, // Implemented by LCD command `36h` .bits_per_pixel = EXAMPLE_LCD_BIT_PER_PIXEL, // Implemented by LCD command `3Ah` (16/18/24) .vendor_config = &vendor_config, }; ESP_ERROR_CHECK(esp_lcd_new_panel_st7703(mipi_dbi_io, &panel_config, &panel_handle)); ESP_ERROR_CHECK(esp_lcd_panel_reset(panel_handle)); ESP_ERROR_CHECK(esp_lcd_panel_init(panel_handle)); ESP_ERROR_CHECK(esp_lcd_panel_disp_on_off(panel_handle, true)); ```
