- Установка TF-карты: If using a TF card, insert it into the TF card slot.
5. Инструкция по эксплуатации
- Программирование платы:
- Open your chosen development environment (e.g., ESP-IDF, PlatformIO).
- Select the correct board target (ESP32-P4).
- Write or load your application code.
- To upload code, press and hold the БОТИНОК кнопку, затем нажмите кнопку РСТ button, and release both. This puts the board into download mode.
- Initiate the upload process from your development environment.
- Отладка: Utilize the USB Type-C port for serial communication and debugging output. Most IDEs provide a serial monitor feature.
- Peripheral Usage: Refer to the ESP-IDF documentation and specific library examples for programming the MIPI-CSI, MIPI-DSI, USB OTG, and other integrated peripherals.
6. Техническое обслуживание
- Умение обращаться: Handle the board by its edges to avoid touching components, especially when powered. Electrostatic discharge can damage sensitive components.
- Уборка: При необходимости аккуратно очистите доску мягкой сухой щёткой или сжатым воздухом. Избегайте использования жидкостей и абразивных материалов.
