stm32 adxl345 olediic

The STM32 is a microcontroller developed by STMicroelectronics. The ADXL345 is an accelerometer sensor developed by Analog Devices, which measures acceleration in three axes. The OLED (Organic Light Emitting Diode) is a display technology that uses organic compounds to produce light.

The I2C (Inter-Integrated Circuit) protocol is used to communicate between the STM32 and the ADXL345 and OLED. The STM32 sends commands and receives data from the ADXL345 and OLED through the I2C bus.

To interface the ADXL345 with the STM32, the following steps are needed:

1. Configure the I2C peripherals of the STM32.
2. Initialize the ADXL345 by writing to its control registers.
3. Read the acceleration data from the ADXL345 and process it as needed.
4. Display the data on the OLED display.

The following code snippet shows an example of reading the acceleration data from the ADXL345 and displaying it on the OLED:

// Initialize I2C peripherals
// ...

// Initialize ADXL345
writeToRegister(ADXL345_ADDRESS, ADXL345_POWER_CTL, 0x08); // Put ADXL345 into measurement mode

while(1) {
  // Read acceleration data from ADXL345
  uint8_t data[6];
  readFromRegisters(ADXL345_ADDRESS, ADXL345_DATAX0, data, 6);

  // Process acceleration data
  int16_t x = (data[1] << 8) | data[0];
  int16_t y = (data[3] << 8) | data[2];
  int16_t z = (data[5] << 8) | data[4];

  // Display data on OLED
  oled.setCursor(0,0);
  oled.print("X: ");
  oled.print(x);
  oled.setCursor(0,1);
  oled.print("Y: ");
  oled.print(y);
  oled.setCursor(0,2);
  oled.print("Z: ");
  oled.print(z);
}
