I'm using a STM32F070CBT and putting it to stop mode with low power regulator on and waking it up with GPIO events.In our project, we're using every single pin from the MCU, most of those are timers and GPIOs, NFC tag reader, etcAfter waking it up, w...
Hey,If a power off occurs, I would like that the RTC function will keep alive, until Power on.As I understand, i should connect a coin battery 3.0 to VBAT pin.My questions are:when power is on, does the VBAT PIN supplies from VDD (P3V3) or from the V...
Hello all,I am unable to save time or restore proper time after I remove Vdd from my MCU when connected to a external 3V li ion battery (DL2032). After every power cycle my time gets reset to its initial default value.When I supply 3V from a regulate...
Hi,I'm trying to port my project over to Keil uVision, but I'm having hard time flashing the device. It seems that my target values are incorrect.I'm looking for help to get me at least some basic settings done in the scatter file and what settings t...
Hi,I am trying to recieve unknown number of bytes using DMA in circular mode. My buffer size is 2048.After reaching this size, CNDTR becomes 0 and never reinitialized again. It stays 0 always. The bytes coming after are getting lost.Has anyone faced ...
Hi everyone,I'm working on a project that used STM32F407VE microprocessor. I'm dealing a memory problem. I have a very big struct that has all systems variable. I create a veraible with this struct and this veraible is larger than 112 kb. When I use...

Hi, we are using STM32H743VIT6 IC for past 3 to 4 years. but from January, none of the newly bought IC is getting programmed via DFUSE. the IC gets connected, erase cycle starts reaches upto 49% and then nothing happens. only the timer is incremented...
The __SIZEOF_FLOAT__ and __SIZEOF_DOUBLE__ macros give the same result in both cases.
Hello ST community,I am using STM32L476RG nucleo board and I am interested in reading the boards pin states while running , especially I would like to debug the serial protocols like SPI, I2C, ...I tried with Cube Monitor but it seems, it is only use...
