Good evening to everyone,I'm trying to sample various signals, both low frequency and high frequency. For the low frequency, I'm using a timer, while for the high frequency, I'm using DMA. I would like to perform read scans with the ADC, selecting th...
i m 3rd year student and i need an idea for project that can use stm32 card only
Hello Community, I am working on a use case where I have 4 remote MCUs that ideally should be synced with a host MCU. I however have no way to even install an external precision Clock source on these remote MCU's (due to various environmental & budge...
Hi all, we've been developing some applications using STM32H743BG since 2020 and only now we realized that value of VECT_TAB_OFFSET has been changed according the package used in STM32Cube. So, these are the differences between different Cube version...
AN5290 discusses a workaround for the "When VDD exceeds 2.5V in LDO configuration a glitch on HSE may create a hard fault on M4/M0" issue identified in the errata. In the AN5290 section titled "1.2 LDO configuration for VDD > 2.5 V" recommends:The r...
Hi,I'm using a NUCLEO-L452RE and wanted to check out current in different low power modes.With only the basic pins configured, I can measure <7uA in Stop2. Not bad.using: HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI);Problem I have is if I configure th...
Dear all,I am using STM32U585CIT6Q in Stop3 mode. When one wakeup pin is active, everything works fine, and I can wake up my microcontroller.But when I want to use two wakeup pins (Two wakeup pins are selected in .ioc file and enabled in code), I can...
Dear friends, good evening.I am facing the following problem with my application using BLE with the MB1641 (STM32WB15CC):We had an app that worked with a device using another microcontroller (Nordic). We are adapting this device to an STM32 platform....
I am using stm32f334r8 for digital power control. I have configured ADC using cube mx Lower level. ADC reads 0 for 40mv input even though ADC is configured to 12bit and 181 sampling cycles. I also tried calibrating ADC before conversion is started. ...
While powering up all of my Microcontrollers were getting shorted, checked the voltages of all the capacitors and the MCU has a dedicated power line . And checked the ripple and initial power up data,everything is fine only. But still the MCU getting...
