What mode can I put my mcu in to consume the least amount of power but still have the ability to "wake up" after an event has been triggered?
I have a stm32 mcu. I want to put it in a very low power mode until an event triggers it to wake up. What mode can give me the lowest power consumption? whilst still being able to accept an event to wake up? and what sort of power would that draw?
Resolved! power consumption in stop modes,standby and shutdown mode
i am trying to measure the power consumption of the MCU in my custom board with different sleep modes, while measuring the stop2 mode i am getting consumption of 110 uA in the datasheet its showing of 2 uA ,even for shutdown and standby mode also its...
STM32WB55 custom board configured as Gatt Slave, after wateup from STOP2 mode UTIL_SEQ_SetTask and HW_TS_Start not working.
Case 1: without STOP2 mode UTIL_SEQ_SetTask or HW_TS_Start working fine.Case 2: without UTIL_SEQ_SetTask or HW_TS_Start calling, the device can go to sleep and wake up without any problem.case 3: when the device wakes up and after the device wakeup,...
How to put the STM32WB55 in STOP2 mode
Hello,The STM32WB55 on our custom board doesn't ever go into stop2 mode. Our application needs to activate BLE and advertise for a fixed time at startup, so that the system can be configured and started. After this period BLE is no longer needed, so ...
wake up CPU1 from CPU2
Hi,in my application on STM32WL55, when the CPU1 (CM4) is on STANDBY mode, and the CPU2 (CM0PLUS) is in Run mode,how can i ask the CPU2 to wakeup the CPU1 ?Thank you.
STM32WLE5 Wake up from stop mode on EXTI for Rx
Hello,I'm trying to create a test application based on the SubGHz_Phy_Per RX example that will go into stop mode after initialization and wake up on EXTI line for an Rx window and then go back to stop mode.I want to base my test application on the Se...
How to wakeup B-L072Z-LRWAN1 by detecting motion and fifo interrupts from ie LIS2DW12?
How can I wake up the B-L072Z-LRWAN1 STM32L072CZ PA0 pin when I want to measure the begin and end of a movement plus gathering measurements from the FIFO after one or several FIFO watermark interrupts?Ideally I want to let the STM32 go back into low ...
