# ESP LCD GC9A01 [](https://components.espressif.com/components/espressif/esp_lcd_gc9a01) Implementation of the GC9A01 LCD controller with esp_lcd component. | LCD controller | Communication interface | Component name | Link to datasheet | | :------------: | :---------------------: | :------------: | :---------------: | | GC9A01 | SPI | esp_lcd_gc9a01 | [WIKI](https://www.waveshare.com/wiki/1.28inch_LCD_Module) | ## 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 esp_lcd_gc9a01==1.0.0 ``` 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 ESP_LOGI(TAG, "Initialize SPI bus"); const spi_bus_config_t bus_config = GC9A01_PANEL_BUS_SPI_CONFIG(EXAMPLE_PIN_NUM_LCD_PCLK, EXAMPLE_PIN_NUM_LCD_MOSI, EXAMPLE_LCD_H_RES * 80 * sizeof(uint16_t)); ESP_ERROR_CHECK(spi_bus_initialize(EXAMPLE_LCD_HOST, &bus_config, SPI_DMA_CH_AUTO)); ESP_LOGI(TAG, "Install panel IO"); esp_lcd_panel_io_handle_t io_handle = NULL; const esp_lcd_panel_io_spi_config_t io_config = GC9A01_PANEL_IO_SPI_CONFIG(EXAMPLE_PIN_NUM_LCD_CS, EXAMPLE_PIN_NUM_LCD_DC, example_callback, &example_callback_ctx); ESP_ERROR_CHECK(esp_lcd_new_panel_io_spi((esp_lcd_spi_bus_handle_t)EXAMPLE_LCD_HOST, &io_config, &io_handle)); /** * Uncomment these lines if use custom initialization commands. * The array should be declared as "static const" and positioned outside the function. */ // static const gc9a01_lcd_init_cmd_t lcd_init_cmds[] = { // // {cmd, { data }, data_size, delay_ms} // {0xfe, (uint8_t []){0x00}, 0, 0}, // {0xef, (uint8_t []){0x00}, 0, 0}, // {0xeb, (uint8_t []){0x14}, 1, 0}, // ... // }; ESP_LOGI(TAG, "Install GC9A01 panel driver"); esp_lcd_panel_handle_t panel_handle = NULL; // gc9a01_vendor_config_t vendor_config = { // Uncomment these lines if use custom initialization commands // .init_cmds = lcd_init_cmds, // .init_cmds_size = sizeof(lcd_init_cmds) / sizeof(gc9a01_lcd_init_cmd_t), // }; const esp_lcd_panel_dev_config_t panel_config = { .reset_gpio_num = EXAMPLE_PIN_NUM_LCD_RST, // Set to -1 if not use #if ESP_IDF_VERSION < ESP_IDF_VERSION_VAL(5, 0, 0) .color_space = ESP_LCD_COLOR_SPACE_RGB, #else .rgb_endian = LCD_RGB_ENDIAN_RGB, #endif .bits_per_pixel = 16, // Implemented by LCD command `3Ah` (16/18) // .vendor_config = &vendor_config, // Uncomment this line if use custom initialization commands }; ESP_ERROR_CHECK(esp_lcd_new_panel_gc9a01(io_handle, &panel_config, &panel_handle)); ESP_ERROR_CHECK(esp_lcd_panel_reset(panel_handle)); ESP_ERROR_CHECK(esp_lcd_panel_init(panel_handle)); #if ESP_IDF_VERSION < ESP_IDF_VERSION_VAL(5, 0, 0) ESP_ERROR_CHECK(esp_lcd_panel_disp_off(panel_handle, false)); #else ESP_ERROR_CHECK(esp_lcd_panel_disp_on_off(panel_handle, true)); #endif ``` There is an example in ESP-IDF with this LCD controller.
