How to Fix X-NEUCLEO LPM01A

I'm monitoring power using an X-NEUCLEO LPM01A and an STM32F767Zi target board. When I use them in standalone mode and connect to a desktop computer, the X-NEUCLEO LPM01A stops working. Can someone tell me how I can repair this?

Do I need ST-LINK/V2-ISOL for STEVAL-ETH001V1?

I bought the STEVAL-ETH001V1 and it is without the firmware loaded.I was previously working with the P-NUCLEO-IHM03 and the B-G431G-ESC1 so I don't have any programmer for the MCU.I think I have to buy the ST-LINK/V2-ISOL but I'm not sureBest regard

How to measure the time difference between master timer compare1 and an external signal which i connected to comp2 and made a zero cross detection of it?

Sampling frequency for STM32L476RG in dual regular simultaneous mode?

I have set the ADC clock frequency to 80 MHz and I am operating the ADC1 and ADC2 in dual regular simultaneous mode where sampling cycles I have set to 2.5cycles each, so what will be the sampling frequency for the signal?

NUCLEO-H723ZG web server with external memory

heyI work with NUCLEO-H723ZG,STM32 Nucleo-144 development board with STM32H723ZG MCU.I try to implement web-server on my board.I work with the example of LwIP_HTTP_Server_Netconn_RTOS.From my test, the size of the website will be larger than 600MB. T...

STM32 metrology driver, HAL returning negative values. QE is questioning why negative values, feels this must be HW or FW bug.

Some of the parameters which can return negative values (not all the time, sometimes positive) are: Power Factor, ReactivePowerReceived, ApparentPowerDelivered, and whatever these parameters are:Vmom = -162  AEload = -0.174030   Imom = -43   PF = -0....

Figure 27 in the STM32F446 data sheet wrong - Anyone knows what is correct?

Hi everybody,I want to compensate the internal RC oscillator drift in a STM32F446RCT6. My idea is to measure the internal temperature and the trim the RC oscillator according to this using the designated register for it. Unfortunately the diagram of ...

Problem with timer interrupt

I am using HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) to generate a sine wave based on DDS and I have also implemented ADC to get the value and perform some calculation. My sampling rate is 100KHz so my timer interrupt should trigger ever...
