3. FUNCTIONAL DESCRIPTION This chapter describes the ESP32-S3 various modules and functions. 3.1. CPU AND MEMORY Xtensa® dual-core 32-bit LX7 microprocessor,up to 240 MHz 384 KB ROM 512 KB SRAM 16 KB SRAM in RTC SPI, Dual SPI, Quad SPI, Octal SPI, QPI and OPI interfaces that allow connection to multiple flash and external RAM Flash controller with cache is supported Flash in-Circuit Programming (ICP) is supported 3.2. STORAGE DESCRIPTION 3.2.1.
• External main crystal clock • Internal fast RC oscillator (typically about 17.5 MHz, and adjustable) • PLL clock The application can select the clock source from the three clocks above. The selected clock source drives the CPU clock directly, or after division, depending on the application. Once the CPU is reset, the default clock source would be the external main crystal clock divided by 2. 3.4.

1. QUICK START 1.1.ARDUINO IDE Visit Arduino's official website(https://www.arduino.cc/en/Main/Software),Select the installation package for your own operating system to download. >1.Open up Arduino IDE, navigate to `File`->`Peferences`->`Settings` >2.Copy the following M5Stack Boards Manager url to `Additional Boards Manager URLs:` https://raw.githubusercontent.com/espressif/arduino-esp32/ghpages/package_esp32_dev_index.json >3.Navigate to `Tools`->`Board:`->`Boards Manager...` >4.
Open the Arduino IDE and open the example program `File`->`Examples`->`BluetoothSerial`->`SerialToSerialBT`. Connect the device to the computer and select the corresponding port to burn. After completion, the device will automatically run Bluetooth, and the device name is `ESP32test`. At this time, use the Bluetooth serial port sending tool on the PC to realize the transparent transmission of Bluetooth serial data. #include "BluetoothSerial.
BluetoothSerial SerialBT; void setup() { Serial.begin(115200); SerialBT.begin("ESP32test"); //Bluetooth device name Serial.println("The device started, now you can pair it with bluetoot h!"); } void loop() { if (Serial.available()) { SerialBT.write(Serial.read()); } if (SerialBT.available()) { Serial.write(SerialBT.read()); } delay(20); } 1.3.WIFI SCANNING Open the Arduino IDE and open the example program `File`->`Examples`->`WiFi`->`WiFiScan`.
#include "WiFi.h" void setup() { Serial.begin(115200); // Set WiFi to station mode and disconnect from an AP if it was pre viously connected WiFi.mode(WIFI_STA); WiFi.disconnect(); delay(100); Serial.println("Setup done"); } void loop() { Serial.println("scan start"); // WiFi.scanNetworks will return the number of networks found int n = WiFi.scanNetworks(); Serial.println("scan done"); if (n == 0) { Serial.println("no networks found"); } else { Serial.print(n); Serial.
