STM32H7 LPTIM5 not waking from stop mode
Hi Forum,
I am using the stm32H743 and trying to keep the power consumption as low as possible by entering sleep or stop mode. I am then using a lptimer to wake the device. Eventually, I will also use the timer to determine how long the device is asleep for.
When I use LPTIM1 this all works fine and the device is woken from sleep or stop mode.
However, I have tried to move across to LPTIM5 and the device will wake from sleep mode, but will not wake from stop mode.
From what I can see in the RM all the LPTIMERS can wake the device from stop mode, but just want to check that I haven’t missed something.
Any ideas are more than welcome!
