How do I implement EEPROM Emulation in STM32H725?
Hi, I want to store 1Kb of configuration data in an internal flash by emulating EEPROM in the stm32h7251gk6 controller. It has only one bank and 8 sectors each 128KB. Can someone guide me, please?

Read battery voltage for external RTC on STM32
I am using STM32F446RE for my application to just log the time accurately. I have an RTC module DS3231SN[1] connected to the STM32 on the I2C. The RTC is connected to a coin cell battery CR2032[2] for a long life on its VBAT terminal. The entire boar...
Resolved! Pin assignment BOOT_0 / 1 and USB_DM / DP
Hello everyone,I'm working on STM32F401RE and I'm in the middle of designing a circuit.I have 2 questions:1- Is it possible to use the USB_DP & USB_DM (PA_11 / PA_12) pins in serial TX & RX mode in addition to the USB_DFU mode? I mean, can I physical...
RSA Signature generated by X-Cube Crypto Library and Python script are not matching even though we used same key for both methods.
Hello All,I Integrated X-Cube-CRYPTOLIB V4.1.0 into my project. My application to generate SHA256 for the "xx_xx.hex " file and generate RSA signature . SHA256 value generated by X-Cube-CRYPTOLIB and python script both are same. But RSA signature is ...
