-
• Audio Drivers: Supporting various audio codecs such as I2S, PDM, etc.
-
• Camera Drivers: Supporting various cameras such as OV2640, OV7725, etc.
-
• Sensor Drivers: Supporting various sensors such as temperature, humidity, pressure sensors, accelerometers, gyroscopes, etc.
-
• Storage Drivers: Supporting storage devices like SD cards, SPI Flash, etc.
-
• Communication Drivers: Supporting various communication protocols such as SPI, I2C, UART, USB, etc.
3. Example Code
ESP-BSP provides various example codes to help developers quickly get started with using different hardware components. For instance, examples for controlling LCD displays, processing touch screen inputs, audio playback, camera image capture, sensor data reading, and more.
4. Component Library
The ESP-BSP software package has been uploaded to the IDF component library, and developers can add it to their projects using idf.py add-dependency.
