Also, ensure that you use the *Peripheral Clock Gating* feature to disable clocks to unused peripherals. - Action: Review your code to identify any unused peripherals and disable them using the RCCAPB1ENR and RCCAPB2ENR registers.
4. Improve Software Efficiency Problem: Inefficient software may keep the processor awake unnecessarily. Solution: Use interrupt-based programming rather than continuous polling loops. Polling keeps the MCU active and consumes more power, while interrupts allow the MCU to sleep until an event occurs. Action: Optimize the application to use low-power sleep modes with proper interrupt handling. For instance, use TIMERS, GPIO interrupts, or USART interrupts instead of polling for data. 5. Optimize GPIO Configuration Problem: Unused GPIO pins are not configured to low-power states. Solution: Configure all unused GPIO pins as inputs with no pull-up or pull-down resistors. This minimizes the power drain from these pins. Action: Review the GPIO settings and ensure that pins not in use are configured to a low-power state, typically input mode with no pull-up or pull-down resistors enabled. 6. Check Voltage Regulation Problem: Inefficient voltage regulation leads to unnecessary power consumption. Solution: Use low dropout regulators (LDO) for lower power loss and ensure that the voltage regulators are supplying the necessary voltage for the microcontroller and peripherals only. Action: Review the power supply circuitry to ensure the regulator’s output is correctly matched to the system’s needs. Check if there are unnecessary regulators supplying power to unused blocks. ConclusionThe power consumption of the STM32G473VCT6 can be optimized through careful configuration of power modes, clock settings, peripheral management, GPIO setup, software efficiency, and voltage regulation. By following these steps, you can minimize the power usage of the microcontroller and improve the overall efficiency of your embedded system. Always remember to perform rigorous testing and profiling to monitor power consumption under different operating conditions and make adjustments as needed.
