@Joseph Ogbonna would like to hear your thoughts on this!!
So many part can affect power consumption, If the MCU is running at it highest clock speed it can increase power. If all peripherals are turned on it can also affect power. But it is dependent on the application and the things functionalities.
Considering the impact of clock speed and peripheral usage on power consumption is crucial. How do you typically balance these factors when designing or optimizing power efficiency in your MCU-based projects?
You can turn off some peripherals when not in use. And reduce clock speed when necessary
Thank you !! Absolutely, selectively disabling unused peripherals and adjusting clock speeds based on the operational requirements are key tactics for efficient power management in microcontroller applications.
How has this approach worked for you in terms of achieving a balance between performance and power efficiency?
Discussion around Power Consumption is a growing around the world mainly when the device is powered by a battery, I have worked of various project where in single charge of the battery system should work for 6 months(tracking solution)
