Espressif ESP32-S3

Esp32-S3 is an MCU chip that integrates 2.4 GHz Wi-Fi and Bluetooth 5 (LE) and supports Long Range mode. The ESP32-S3 runs on an Xtensa® 32-bit LX7 dual-core processor with a high frequency of 240 MHz, 512 KB built-in SRAM (TCM), 45 programmable GPIO pins, and a rich communication interface. Esp32-s3 supports larger capacity of high-speed Octal SPI flash and off-chip RAM, and supports user-configured data caching and instruction caching.

What follows is a description of the most important features of ESP32-S3.

  • Wi-Fi + Bluetooth 5 (LE) Wireless Connectivity: ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmission speed and data throughput, with 2 Mbps PHY. Both Wi-Fi and BLE have superior RF performance that is maintained even at high temperatures.
  • AI Acceleration Support: ESP32-S3 has additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal processing workloads. The software libraries for the above-mentioned optimized functions will become available very soon, in the form of updates to ESP-DSP and ESP-NN.
  • Rich IO interfaces: ESP32-S3 has 45 programmable GPIOs and common peripheral interfaces such as SPI, I2S, I2C, PWM, RMT, ADC, UART, SD/MMC host controller and TWAITM controller. Fourteen of the GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition, ESP32-S3 is equipped with an ultra-low power coprocessor (ULP) and supports multiple low-power modes, making it widely applicable to various low-power application scenarios.
  • Security mechanism: ESP32-S3 provides comprehensive security mechanism and protection measures for iot devices to prevent all kinds of malicious attacks and threats. It supports Flash encryption based on AES-XTS algorithm, secure startup based on RSA algorithm, digital signature and HMAC. Esp32-s3 also includes a new "World Controller" module, which provides two non-interfering execution environments to implement a trusted execution environment or permission separation mechanism.

ESP-IDF

Esp-idf-logo.png

ESP-IDF is an IoT development framework officially launched by Espressif, supporting Windows, Linux and macOS operating systems.

It is recommended that developers install ESP-IDF via an integrated development environment (IDE):

Or select the corresponding manual installation process according to the operating system:

API:

In order to enable your BPI-Leaf-S3 development board to flash FLASH through USB-CDC, you need to set the development board to firmware download mode.

There are two methods of operation:

1. Connect to the computer via USB, press and hold the BOOT button, then press the RESET button and release it, and finally release the BOOT button.

2. Press and hold the BOOT button when the power supply is disconnected, then connect to the computer via USB, and finally release the BOOT button.

You need to confirm the interface in the device manager. The serial number of the interface in the firmware download mode and the normal mode may be different.

MicroPython

Mircopython.png

MicroPython implements most of the features and syntax of Python 3, which is easy to learn and use, and can be downloaded directly into the chip to run the verification program without compiling.

Regardless of whether you have a programming foundation or not, MicroPython is far less difficult to get started with than other programming languages. Its code is easy to read, and the open source community has accumulated rich resources over the years. Just like Python, it has strong vitality and application value.

Arduino
