Resolved! Initializing RTC with battery backup on STM32H7747I-DISCO board
My very smart technicians say they can cut SB16 from +3V3 and they can solder a 3V CR2032 battery socket onto the STM32H747I-DISCO board safely. It is not an easy job they say. I agree.Unfortunately, STM does not provide a battery backup socket for u...

Split from Black Pill: Debugging STM32F103RCT6 in Keil Fails to Enter main()Hi @mƎALLEm , just about your "not genuine" statement:>- No "ARM " markingSame here on a F103 by STM , should be genuine, because its st-link on a F3-discovery board !>- The...
[solved]STM32G RTC sets to some value afterr reset
Hello,I have an application which I would like to build on to of cubeMX generated HAL driver, but I came across strange issue that I am unable to keep RTC value on reset. Drivers part is as generated with cube using freeRTOS. system reset is triggere...
Resolved! DBANK Option Byte default STM32G4
What is the default value of the DBANK bit in STM32G4 MCUs. According to the reference manual, flash memory address 0x1FFF 7800 has that option bit, and the ST production value is 0xFFEF F8AA, which would make DBANK default to 1. Does this mean STM32...

Hi,I am using STM32C071CBT6 chip on my custom board. From datasheet, i could see that there are two versions available - GP and N version. Part number section of datasheet mention about 3 more characters after this part no. to identify if it is N ver...
Resolved! Implementing STM32L4S5ZIT6 Bootloader with a Memory Marker
Hello, I am working on the development of a bootloader for the STM32L4S5ZIT6, and I need help to implement a feature where the bootloader is triggered after receiving a user request in the main application (the main app saves a marker in memory). Her...
SPI slave on STM32U535
Hi,I'm trying to implement SPI slave on STM32U535 ( I have also NUCLEO-U575I). I need the SPI slave to have 4 bytes communication, 1st byte is a command byte, that has 2 options of command, the next 3 bytes the slave sends the content of one of 2 arr...
Help with Ethernet on STM32 H723ZG
Hi all! I have been using a F446RE board to communicate with an encoder using SPI. I get back a 16-bit value every ms (the process runs at 1kHz). However, I now need to transfer the acquired data over ethernet (it has to be ethernet, not UART or anot...
