Hardware Version Info

This board is the standard version. It does not include an onboard Ethernet PHY (can be expanded via SPI/RMII). The audio circuit uses MSM261D (Mic) and NS4168 (Amp).

3. Software

We provide a comprehensive collection of code examples based on ESP-IDF.

3.1 Getting Started

3.1.1 Preparation

  • Hardware: ESP32-P4-SmartDisplay Board, USB-C Cable.

  • Software: ESP-IDF v5.2 or later (Required).

3.1.2 Build & Flash Steps

  1. Clone the Repository 

    git clone https://github.com/VIEWESMART/ESP32-P4-SmartDisplay.git

  2. Set Target 

    idf.py set-target esp32p4

  3. Wi-Fi Configuration (Important) Since P4 uses C6 for Wi-Fi via SDIO, you must add these dependencies: 

    idf.py add-dependency "espressif/esp_wifi_remote"
idf.py add-dependency "espressif/esp_hosted"

  4. Build & Flash 

    idf.py build flash monitor
