I am Currently working on STM32 Low Power Mode and For an Application, I have to Wake Up the Controller from CAN Receive Interrupt. Although In the Datasheet it is mentioned that wakeup is possible using External Interrupt and RTC but I would love to understand, is there any method to Implement Stop Mode and Wakeup using CAN Receive Interrupt. Currently I am using HAL Libraries for the Development.
There is no option to wake up from stop mode from CAN on the STM32F4.
Look in the reference manual for a better description of how the low-power modes work. In particular, look at "5.3 Low-power modes".
