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 project. For change the Espressif's board, go to 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:

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 for full steps to configure and use ESP-IDF to build projects.
