HelloWhat will happen with the IOs when MCU is put to Sleep mode (one of power modes in PWR) and register bits in RCC_AHB2LPENR for each GPIO-block are reset? When bits are reset, the peripheral clock is disabled during Sleep mode.Can the IOs still b...
HiIn the reference manual, RM0481 rev1, for analog watchdog window it mentions SQRi and JSQRi registers. I can not find any descriptions about these registers.Can someone help me clarifying this?BrImre
Hi STI am using STM32CubeMX v6.10.0 with selected MCU STM32H563ZITx.When configuring FDCAN1 I may have found a bug in the tool. The below two Nominal Time Seg1 and Seg2 say that the lowest value is "2" and the tool is limiting setting it to "1" which...
Is it possible for STM32H5 to monitor the CAN bus when MCU is in sleep mode? Upon CAN bus activity detection, MCU automatically performing the wakeup sequence to be back in normal run mode.
Yes, the application should disable everything that is not needed in the sake of saving power. When EXTI detects activity, the application can reconfigure itself to handle the activity.
With all respect, you did not answer the question related to sleep mode. You mentioned stop mode which is another mode. There are sleep, stop and standby modes.Let me rephrase my question:In sleep mode and when GPIO peripheral clocks are disabled by ...
Yes, more details come.STM32L4:It has a low power mode that is able to detect activity on CAN bus.STM32H5:It does not have a low power mode, but only a power down mode and in that mode it can not detect activity on the CAN bus.
Hi IssamosThank you for the answer, I understand it and it answers the question. I am used to STM32L4 where bxCAN could be set to sleep along with the MCU and upon CAN bus activity woken up and also the MCU.For STM32H5 it seems that FDCAN can not be ...
