How to Use Nucleo WB55RG: Examples, Pinouts, and Specs

The Nucleo WB55RG is a development board featuring the STM32WB55 microcontroller, which supports Bluetooth Low Energy (BLE) and IEEE 802.15.4 wireless communication. Manufactured by STMicroelectronics, this board is designed for prototyping and development of IoT applications. It provides a versatile platform for developers to create and test wireless communication projects, making it ideal for smart home devices, wearable technology, and industrial automation.

1. Power Supply: Connect the VDD pin to a power source within the range of 1.7V to 3.6V and connect the GND pin to the ground.
2. GPIO Configuration: Configure the GPIO pins as needed for your application. For example, if you need to use PA0 as an analog input, configure it accordingly in your code.
3. Communication Interfaces: Utilize the I2C, SPI, UART, USB, or CAN interfaces for communication with other devices. Ensure proper configuration of the respective pins.
4. Wireless Communication: Use the BLE and IEEE 802.15.4 capabilities for wireless communication. Ensure proper initialization and configuration in your firmware.

• Power Management: Ensure that the power supply is stable and within the specified range to avoid damage to the board.
• Pin Configuration: Double-check the pin configuration in your code to avoid conflicts and ensure proper functionality.
• Firmware Updates: Keep the firmware updated to the latest version to benefit from bug fixes and new features.
• Debugging: Use the SWD interface for debugging and troubleshooting your code.

#include <Wire.h>

// Define the I2C address for the STM32WB55RG
#define STM32WB55RG_I2C_ADDRESS 0x68

void setup() {
  // Initialize I2C communication
  Wire.begin();
  
  // Initialize Serial communication for debugging
  Serial.begin(9600);
  
  // Wait for Serial to initialize
  while (!Serial) {
    ; // Wait for Serial to initialize
  }
  
  Serial.println("STM32WB55RG I2C Communication Test");
}

void loop() {
  // Request data from the STM32WB55RG
  Wire.beginTransmission(STM32WB55RG_I2C_ADDRESS);
  Wire.write(0x00); // Register address to read from
  Wire.endTransmission();
  
  Wire.requestFrom(STM32WB55RG_I2C_ADDRESS, 1);
  
  if (Wire.available()) {
    int data = Wire.read();
    Serial.print("Data received: ");
    Serial.println(data);
  } else {
    Serial.println("No data received");
  }
  
  delay(1000); // Wait for 1 second before next request
}

1. Power Issues: The board does not power on or resets frequently.
2. Communication Failures: Unable to establish communication via I2C, SPI, UART, etc.
