If the internal oscillator clock is switched off during a low-power mode, the maximum baudrate to correctly wake up an STM32 MCU from a low-power mode depends on the following criteria: • the wake-up time parameter (t. To guarantee that the device does in fact sleep code should check the wake-up flag (defined as PWR_FLAG_WU in the ST libraries). I managed to write and run a program that demonstrates using timed-based sleep and external-interrupt-based sleep in the same program. Also consider the iwatchdog timer implications if you are designing a system which puts the CPU in sleep mode. However, it only works if Serial/hardwareSerial is not used in the program. Then I have to find out other solutions Mar 13, 2020 · Most software I've seen written doesn't take into account the fact that entry into sleep mode could have actually failed, resulting in inconsistent behavior when using a debugger or lots of interrupts. 5. See script below. 0. When it goes into low-power sleep mode though, the watchdog timer remains activated and will reset the entire MCU after the timer goes to 0, making it seemingly impossible to use both the watchdog and low-power sleep mode at the same time.
