# 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 SPI-interfaced LCD
|
||
|
|
* An USB cable for power supply and programming
|
||
|
|
|
||
|
|
### Hardware Connection
|
||
|
|
|
||
|
|
The connection between ESP Board and the LCD is as follows:

### 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-]``.)
