I'm using the stm23F103C8 and I would use the RTC internal cloak/calendar. The program is working fine and I have used the LSE osc (32KHz..) as clock source. I have connected a 3V battery to the VBAT pin. My problem is that the switching off the main...
Hello folks!The STM32H743VC Processor has two pins, that have a "_C" at the end of the name:Pin 17: "PC2_C" and Pin 18: "PC3_C" When I want to know what the C means, the Datasheet says: refer to the reference manual.DS12110 Rev 10 - page 67 - Pin De...

Can someone tell me if I’m understanding this correctly?In the documentation for the STM32F030R8T6 chip, specifically the "RM0360 Reference Manual", there’s a diagram showing how to connect an external crystal oscillator ("Figure 12. HSE/LSE clock so...
Hello,I am working with the STM32H503CBT6 and using the I3C Transmit_IT in Controller mode for communication.However, I encountered a problem, when I sent more than 260+ bytes, the data sent by the logic analyzer to capture, found that the captured d...
I am designing an STM32N657X0 based custom PCB which has a USB Type C port. The USB device would be self- powered, i.e, it will not be powered from VBUS. The intended use of this port is to plug the PCB to a host PC, similar to USB flash drive for da...
Hi,The recent webinar with your partner Edge Impulse on 26th March was useful to taste the capabilities of STM32N6. Until now in my previous STM32 MCU projects are built with ST official tools like STM32CubeMX. But there is no much information availa...
Hi, I'm following the steps on the reference manual to perform in-application programming by first writing the new firmware to bank 2 and then swapping the banks after doing some checks. After completing the steps and performing a software reset, the...
hello. I was using PA9 pin as an interrupt in a project made with Stm32F072CBT6. I am working as Stm32F072CBTx in cubeide. The card I am working on accidentally installed Stm32F072C8T6. only difference is that it is visible in flash but PA9 pin can b...
This is a long and weird one.My boss gave me a board with an STM32L433 that wouldn't communicate or do anything after power-on. After a lot of debugging and code tracing, I discovered that the function HAL_RTC_WaitForSynchro returns a HAL_TIMEOUT err...
