Nice Video. But do u know how to use it with touch gfx? I want to put whole microcontroller to sleep while waiting for another sync signal triggered by interrupt.
Thanks in advance. One question: it makes sense that the two concepts of Sleep Mode and IWGT coexist? I explain that, in my While (1) I have written the next code: while (1) { HAL_IWDG_Refresh(&hiwdg); HAL_SuspendTick(); HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI); } What I want is for the MCU to go into SllepMode until it is woken up by an external interrupt, but at the same time to have the IWDG to watch if the program "hangs", ...does that make sense, is it correct?
IWDG do work in standby. But I guess you need to exit the standby mode, then refresh the watchdog and go back to standby. I am not sure about this, check the reference manual for more information.
If we are measuring a current of milliampere, it's probably wrong.The reason of this, in the state of the measurement ST_Link is connect our board. I think should use custom board to see low power modes current consumption.
I think the ST-Link is not affected by this current because it is first powered by the USB port. Thus, only the current for the Stm32 is measured via the IDD jumper JP5. And if you want to be sure, then you can use an external source, disable ST-Link and use JP5 for current measurement.
I want to be in lowest power mode but I want to see the values of variables at Live Expressions eve I entered that power mode as well what should I use ?
Best channel for stm32 videos. ❤
Kindly make videos on how to add CMSIS DSP Library (FFT or filters) support to stm32.
Thank you so much for saving my school project , video’s awesome!
you are best teacher to stm32 bro thks

Thank you for a great tutorial!
Thank you Controllers Tech

great job tahnk you. Could you also share a video about USB mass storage??
Thank you for your useful tutorial
I absolutely hate the speech synthesised voice but the video content was great, cheers.

thank you for the great video, how can I stop the sleep mode with a timer interrupt ? thank you very much for help!
I think any interrupt should wake the mcu from the sleep mode. So you can just use timer in the interrupt mode and it should do the job.
is it possible to wake from sleep mode when something is received on UART?
uart gets disabled during sleep
what is 1.8V domain clock means?
how much current can produce by a pin in stm32f4
Please check the datasheet for your mcu.
thanks for sharing
Start from there.
