| # ESP LCD EK79007 | ||
|
|
||
| [](https://components.espressif.com/components/espressif/esp_lcd_ek79007) | ||
|
|
||
| Implementation of the EK79007 LCD controller with esp_lcd component. | ||
|
|
||
| | LCD controller | Communication interface | Component name | Link to datasheet | | ||
| | :------------: | :---------------------: | :------------: | :-----------------------------------------------------------------------------------: | | ||
| | EK79007 | MIPI-DSI | esp_lcd_ek79007 | [PDF](https://dl.espressif.com/AE/esp-iot-solution/EK79007DA-H3_DS_V0.01_20200819.pdf) | | ||
|
|
||
| **Note**: MIPI-DSI interface only supports ESP-IDF v5.3 and above versions. | ||
|
|
||
| ## 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_ek79007" | ||
| ``` | ||
|
|
||
| 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 ek79007_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}, | ||
| // ... | ||
| // }; | ||
