CPU Temperature Example

This is the simplest example and a good starting point for a new node. It reads the STM32's internal temperature sensor and ADC pins, then broadcasts a DroneCAN BatteryInfo message at 10Hz containing:

  • voltage — raw ADC reading from PA1
  • current — raw ADC reading from PA0
  • temperature — MCU core temperature in degrees Celsius

It also demonstrates reading and writing parameters via dronecan.getParameter() and dronecan.setParameter().

Dependencies

No extra libraries required. Uses the STM32 internal ADC (AVREF, ATEMP) which is available on all supported boards.
