Demo Applications

This page catalogs the available demo applications for the ESP32-P4-WIFI6-DEV-KIT. Demos are organized by framework.

Arduino demos

These demos use the Arduino framework with the Arduino-ESP32 core. They require the dependencies listed in each row.

Demo	Description	Dependencies
HelloWorld	Basic graphics rendering test. Draws shapes, text, and color fills on the connected MIPI-DSI display. Useful as a first validation that the display pipeline is working.	GFX_Library_for_Arduino, compatible DSI display
Drawing_board	Touch-based drawing application. Tests both the MIPI-DSI display output and the touch input on supported panels. Draw with your finger and verify display + touch calibration.	GFX_Library_for_Arduino, compatible DSI display with touch
AsciiTable	Renders a grid of ASCII characters on the display. Demonstrates font rendering and character spacing with the GFX library.	GFX_Library_for_Arduino, compatible DSI display
GFX_ESPWiFiAnalyzer	WiFi spectrum analyzer that scans available networks and displays signal strengths in a graphical bar chart. Tests both the ESP32-C6 WiFi subsystem and the display output simultaneously.	GFX_Library_for_Arduino, compatible DSI display
LVGLV9_Arduino	Runs the LVGL v9 built-in demos (widgets, stress test, benchmark, music player) on the MIPI-DSI display. Demonstrates LVGL integration with the ESP32-P4 hardware acceleration.	LVGL (v9), GFX_Library_for_Arduino, compatible DSI display

Note

All Arduino display demos require a compatible MIPI-DSI display panel connected to the DSI FPC port (component 14). The supported panels are 5”, 7”, 8”, and 10.1” DSI screens listed in the Waveshare wiki. Check that your panel’s resolution and driver IC match the demo configuration.

Arduino library dependencies

Library	Source	Purpose
GFX_Library_for_Arduino	Arduino Library Manager / GitHub	Graphics abstraction layer for display rendering
LVGL	Arduino Library Manager / GitHub	GUI framework (v9 required for P4 support)

ESP-IDF demos

These demos use the Espressif IoT Development Framework (ESP-IDF) and provide access to the full hardware feature set.

Demo	Description	Hardware Used
SDMMC	SD/MMC card read/write test. Validates the SDIO 3.0 TF card slot (component 24) with file creation, write speed, and read verification.	TF card slot
WiFi	WiFi connectivity demo. Tests station mode (connect to AP), scan, and basic data transfer through the ESP32-C6 co-processor over SDIO.	ESP32-C6 (WiFi)
I2S Audio	Audio playback and recording test. Plays a tone through the speaker/headphone outputs and records from the onboard microphone using the ES8311 codec.	ES8311, NS4150B, microphone, speaker/headphone
I2C	I2C bus scan and device communication test. Scans the default I2C bus (SCL/GPIO8, SDA/GPIO7) and reports detected device addresses.	I2C bus
MIPI-DSI Display	MIPI-DSI display initialization and rendering test. Configures the D-PHY, initializes the display panel, and renders test patterns.	MIPI-DSI display
Camera (MIPI-CSI)	Camera capture test. Initializes the MIPI-CSI interface and ISP, captures frames from a connected camera module, and optionally displays them on the MIPI-DSI output.	MIPI-CSI camera module
ESP-Phone (Brookesia)	Full-featured phone-like application using the Brookesia UI framework. Demonstrates the integrated use of display, touch, audio, WiFi, and Bluetooth in a cohesive application.	Display (touch), audio, WiFi, Bluetooth

Tip

The ESP-Phone / Brookesia demo is the most comprehensive example of the board’s capabilities. It exercises nearly every subsystem simultaneously and serves as a good reference architecture for complex applications.

Framework comparison for demos

Capability	Arduino	ESP-IDF
Display (MIPI-DSI)	Via GFX library	Direct hardware access
Camera (MIPI-CSI)	Limited	Full ISP + H.264 support
Audio (I2S)	Basic	Full codec control
WiFi 6	Yes (via ESP32-C6)	Yes (via ESP32-C6)
Bluetooth 5 LE	Yes	Yes
USB OTG	Limited	Full HOST/DEVICE support
SD Card (SDIO 3.0)	Yes	Yes
Ethernet	Yes	Yes

Note

ESP-IDF provides the most complete access to all hardware features, particularly the MIPI-CSI camera with ISP, H.264 encoding, and advanced USB OTG capabilities. Arduino is suitable for display-centric applications and rapid prototyping.

Running the demos

Demos are available from the Waveshare ESP32-P4-WIFI6-DEV-KIT Wiki downloads section and from the Espressif example repositories. See the Getting Started section for environment setup instructions.
