The NUCLEO-G071RB development board used in this experiment is provided by https://www.stmcu.com.cn/index.p%20...%20/261/layout/product https://www.stmcu.com.cn/index.p ... /261/layout/product. For more information, please go to the search. This experiment uses the USER key on PC13 (System Wake-Up2 wake-up function pin) and demonstrates the working status of LD4. 1. Experimental resources 1. NUCLEO-G071RB development board; 2. Keil v5.25.2.0; 3. STM32CubeMX v5.0.1; 4. Logic analyzer; 2. Experimental process 1. Resource allocation. System Wake-Up has a total of 5 pins on the STM32G071RBT6 microcontroller as a system wake-up source, including System Wake-Up (1, 2) and System Wake-Up (4, 5, 6). Here, the System Wake-Up2 on the USER button is used. After the system is turned on, LD4 works for 3 seconds and then enters the shutdown mode to wait for the system to wake up. When the USER button is pressed, the system wakes up and enters the working state. 2. Program implementation. The code is relatively simple, which is the few sentences listed in the figure below. 3. Experimental Results Below are the test photos of working and stopping 4. Experimental Summary This experiment is relatively simple, and we are going to use the stop mode for actual application in a specific project.

Where does the code start executing after waking up from standby mode?

Waking up is equivalent to a cold start.
