* This is a simple IoT photo frame sample
|
|
* Please find more details at instructables:

* https://www.instructables.com/id/Face-Aware-OSD-Photo-Frame/
|
|
*
|
|
* Dependent libraries:
|
|
* JPEGDEC: https://github.com/bitbank2/JPEGDEC.git
|
|
*
|
|
* Raspberry Pi Pico W dependent libraries:
|
|
* HttpClient: https://github.com/moononournation/HttpClient.git
|
|
*
|
|
* Setup steps:
|
|
* 1. Fill your own SSID_NAME, SSID_PASSWORD, HTTP_HOST, HTTP_PORT and HTTP_PATH_TEMPLATE
|
|
* 2. Change your LCD parameters in Arduino_GFX setting
