Question, if during stop mode it can wake up from any EXTI line, but EXTI lines are just GPIO's and GPIO's need a clock to function just like all other peripherals, how does the EXTI interrupt trigger if stop mode disables the HSI/HSE and PLL clock? To me it seems like there is no clock available for the GPIO peripheral and therefore the interrupt shouldn't work, but in the video it does.
you're a godsend. Thank you so much ! I was wondering if you knew of a way to do this WITHOUTusing HAL library,just register manipulation.Mainly how to wake up the mcu from sleep mode using an interrupt caused by one of the USART channels?
Hi! Thanks for your video it really helped me to understand sleep mode for my STM32 Nucleo L073RZ, however I have some questions, hope you can help me with this: 1. I am using an external power supply to power up the microcontroller, but I am noticing that if I measure the current only with the external supply I am getting 50mA but If I connect the microcontroller to the computer the current goes down to 10mA, is this Beauvoir normal? 2. For me the sleep mode is not working and I don't know why, I am doing the exact thing that you are doing in your video, but the current doesn't drop at all, I am not sure what is happening, I am opening a clean project using the stm32cudeIDE and put the lines, but the current remain the same, I am not sure what is happening, any idea? Thanks! greeting from Mexico (:
I have just discovered your channel, great video series thank you
You're welcome! :)
I hope you get 1k plus subs soon.
good luck with your work. Thank you so much
Thank you. Now it’s not difficult for me to make the transition to low-power modes for my project. Very intelligible!
