Module 10
Power Management and Optimization
1
Understanding Low-Power Modes from Device Datasheets
Identify the different low-power modes (Sleep, Stop, Standby) from the device datasheet.
2
Interrupts for Low-Power Operation
Implement interrupt-driven logic to replace polling and enable low-power modes.
3
MCU Sleep and Stop Modes with EXTI Wake-up
Place the MCU into Sleep and Stop modes and wake it using an external interrupt (EXTI).
4
Optimizing Power with RCC Peripheral Clock Control
Disable unused peripheral clocks in the RCC to minimize power consumption.
RTC Wake-Up Configuration
Configure the Real-Time Clock (RTC) to wake the system from a low-power mode.
6
Measuring MCU Current Consumption with a Multimeter
Measure the MCU's current consumption in different operating and low-power modes using a multimeter.
Compiler Optimization for Size and Speed
Optimize C code for size and speed using compiler flags and analyze the impact on the memory map.
