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...
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...
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 ...
Hello All,I want to generate a different type of PWM along with its phase shift PWM as well. Below is the diagram for the output waveform. I am using the NUCLEO-F030R8 board as of now.(Sorry for the bad drawing)Where Fhz and Th are the same for all i...
I want to konw voltage stability of 3.3V, but there is no details in official docment. i need the voltage to power a sensor
Hello everyone,Since can I switched to STM32F401RE. Since impossible to compile with MODSERIAL.I’m compiling on MBED StudioMED OS 5.15.7Here is the errorMODSERIAL_NUCLEO_F401RE.cpp:5:17: error: 'struct serial_t' has no member named 'index' switch( _...
Dear ST,I am trying to configure a voltage follower usin intenal op-amp for external voltage monitoring. And we are going to read that value through ADC.Therefore, it is necessary to select the resistance value of the voltage divider.So I want to kno...
Why using:/* Fill EraseInit structure*/ EraseInitStruct.TypeErase = FLASH_TYPEERASE_PAGES; EraseInitStruct.Banks = FLASH_BANK_1; EraseInitStruct.Page = StartPage; EraseInitStruct.NbPages = ((EndPage - StartPage)/FLASH_PAGE_SIZE) +1; /* F...
