# LCD tjpgd example
This example shows how to decode a jpeg image and display it on an SPI-interfaced LCD, and rotates the image periodically.
Example using initialization of the LCD from [ESP-BSP](https://github.com/espressif/esp-bsp) project. For change the Espressif's board, go to [idf_component.yml](main/idf_component.yml) and change `esp-box` to another board from BSP.
## How to Use Example
### Hardware Required
* An ESP development board
* An SPI-interfaced LCD
* An USB cable for power supply and programming
### Hardware Connection
The connection between ESP Board and the LCD is as follows:
```text
ESP Board LCD Screen
+---------+ +---------------------------------+
| | | |
| 3V3 +--------------+ VCC +----------------------+ |
| | | | | |
| GND +--------------+ GND | | |
| | | | | |
| DATA0 +--------------+ MOSI | | |
| | | | | |
| PCLK +--------------+ SCK | | |
| | | | | |
| CS +--------------+ CS | | |
| | | | | |
| D/C +--------------+ D/C | | |
| | | | | |
| RST +--------------+ RST | | |
| | | | | |
|BK_LIGHT +--------------+ BCKL +----------------------+ |
| | | |
+---------+ +---------------------------------+
```
The GPIO numbers used by this example is taken from BSP.
### Build and Flash
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project. A flowing picture will be shown on the LCD screen.
(To exit the serial monitor, type ``Ctrl-]``.)
See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
