STM32 MCUs Products

Hello, I am trying to measure the power consumption of the STM32U575ZI microcontroller on the Nucleo-144 board but the results are much higher than expected.

 I am using an ammeter connected instead of the JP5 jumper, as indicated in the manual (UM2861) and tried several examples.For example: in PWR_EnterStopMode example I see around 568uA on the ammeter.From the datasheet I expected to measure around 100...

I am developing a STM32L431 based system. I have developed two bin files, one starting from 0x08000000 and the second starts from 0x0802f800. I can jump fom first program to the second in dubug mode. But in normal running mode, it doesn't jump to the 2nd.

Two leds based on one interrupt line

Dear sir,I am using STM32F769NI microcontroller. I want to glow to different Leds on one external interrupt line i.e. Led1 on rising edge and Led2 on falling edge. Can you please suggest me the solution.Regards,Manoj

LL_TIM counter seems not actually counting.

I have this code: //SystemCoreClock=64 MHZ LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM6);  LL_TIM_SetPrescaler(TIM6, __LL_TIM_CALC_PSC(SystemCoreClock, 1000)); /* 1 tick /1 ms */LL_TIM_EnableCounter(TIM6);time0 = LL_TIM_GetCounter(TIM6);LL_mDela...

STM32l4 doesn't quit STOP2 mode if not debugging

Hello STM32-Community,right before finishing work and everything working arguably fine, I was trying to measure the power consumption of my periphery, where I could see that the program stopped working. I've pinned down the problem to not reentering ...

Is it normal to have to manually press the reset button on the development boards to connect to the development boards?

Hi! I am grad student that is a newcomer to the STM32 MCU platform. I want to ask a question about the problems I have been experiencing with my development boards. Is it normal to have to manually press the reset button on the development boards to ...
