I entered STOP mode and returned to NOMAL mode, but ADC does not work.

Currently using STM32L496.

Pressing the button long key enters STOP mode as shown below.

HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);

Additionally, you can exit STOP mode by pressing the interrupt button.

For reference, after exiting normal mode, use SystemClock_Config(); You must enter to return the timer to its original state.

When you press the interrupt button, it exits STOP mode and returns to NOMAL mode (TIMER, UART, I2C, SPI, LCD, etc. all operate normally.)

However, only the ADC does not work.

Is there any additional code that needs to be added after exiting the interrupt?

Hello @JKim.15,

Try calling HAL_ADC_MspInit after waking up from stop mode
