I am currently using an STM32L011F4U6 to communicate with some other chips and it is failing to pull either I2C line down to GND fully when signalling, they are seemingly clamped to approximately 1.2V at a minimum as shown below making it impossible ...
I wonder if any one can help me.The rtc Cal freq produced by the init code below produces on 490Hz. The RTC clock is loosing about 55 sec in 20 minutes.Is there a way to increase this freq without replacing the crystal? static void MX_RTC_Init(void)...
Hello,I am currently reviewing a hardware design based on the STM32H563ZIT6 and have some questions regarding the internal and external behavior of the NRST pin.My main question is how the NRST pin operates specifically during an NVIC_SystemReset.Cur...
May I ask how the FDCAN Message RAM offset allocation, Tx and Rx BufferElementSize can be configured on G4 Series. As in cubeMX it doesnt give me the option to like the H7 series. Or is that done automatically by the core when generating the code?If...
Hi!In version 4 of the reference manual for STM32U0, it is suggested that BOR is enabled and on Level 3 from the factory.Is that correct?I'm currently working on an construction running @ 2V, so it would never start up, if so. And when I read out the...
We are using an STM32G070 with 64 Pins.The clock comes from an external 32,...kHz crystal. For clock calibration, we enable the RTC calibration output PC13.Whenever this is active, reading the state of the input PA4 always returns false, although we ...
Hi,I have a strange problem on an STM32L051C8 with the comparators enabled in window mode.If I put the system in stop about 20 seconds after powering the microcontroller, the current draw is about 250 uA. If I then exit the stop mode with a soft rese...
I need to create a UART driver that works reliably in all conditions.The driver must use DMA, and since the incoming messages are NOT fixed-length, I need to use idle line detection.My question is: how can I use a callback to store the received mess...
I am working on STM32h747 series. I am debugging both CM4 and CM7. After a while, CM4 stops responding and the debug messages shows:"Error in final launch sequence: Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK dev...
Could you please help me find out how much internal storage space this model STM32F427VIT6 has? Thanks a lot.
