Example Code

This example shows how to read the ‘application version number’ value of the bootloader settings.

void setup()
{  
  Serial.begin();
  while (!Serial) 
  {
    yield(); // wait for PC CAN2SER-monitor to open 
  }
  
  Serial.println("appl. version: V"+ String(BOOTLOADER_SETTING.u32_get_app_version()));
}

void loop () 
{
}

Notes and Warnings

This method returns the RAM copy value of the bootloader settings which are copied into the BOOTLOADER_SETTING object during its instantiation at system start (variant.cpp).

The application version can be any number (uint32-range) give by the developer. It will be taken from the .hex/.bin file name. The tool chain automatically creates a version number each time the sketch is compiled and uploaded to the target.
