ESP-DSP ESP32-Azure IoT kit 3d graphics demo application

The demo is developed for ESP32-Azure IoT kit development board and is demonstrating the usage of matrices with ESP-DSP Mat class, Kalman filter and basic 3D graphics.

The 3D Graphics demo displays a 2D graphics, converted to 3D as a 3D rotating object, on the development board's display. Button press changes the rotation direction of the 3D object. Run the menuconfig using the following command:

idf.py mencuonfig

In the menuconfig's menu item Demo user configuration select which 3D object to display. It's either a 3D cube, or ESP logo, or a user-defined graphics. Getting the user-defined graphics is described in an example

Running the demo

To start the demo, run the following command:

idf.py build flash monitor

The expected output is the following:

I (570) 3D image demo: Selected 3D image - ESP Logo I (570) 3D image demo: Showing ESP text I (6730) 3D image demo: Showing 3D image

Note, that the first line Selected 3D image from the expected output depends on the user's Kconfing menu selection
