STM32G030: Is it possible to write a serial number or unique product information?
I know this could be done with an external chip, but I want to know if it's possible to do it directly in the micro. I will appreciate any suggestions.

Implementation of Flow Control in STM32F427VI
Hello everyone.I have an issue with the communication between STM32F427VI to Gemalto PLS-W.The uart that is configured as the following:void MX_USART3_UART_Init(void) { huart3.Instance = USART3; huart3.Init.BaudRate = 230400; huart3.Init.Word...
CAN-BUS normal mode is not working, but loopback mode works fine using CAN Isolator click module (ADM3053)
Hi,I am using two STM32F103 Nucleo boards and STM32CubeIDE.I can see in the oscilloscope the Tx sinal outputs some data when the mode is configured as loopback. But when I switch the mode to normal I can see in the oscilloscope only a short low level...
STM32H7 XiP poor performance with QSPI NOR Flash
I've been developing a solution around the STM32H750 that requires external flash to run relatively large firmware images, up to around 2Mb.The NOR Flash part used is the Cypress s25fl064l, in QSPI configuration. It has quad read rates of up to 54Mbp...
RTC alarmA and alarmB wake up
Hi,I am using nucleo-476Rg board.I have configured RTC AlarmA ad AlarmB for different timings, then I go in standby mode.The board wakes up from standby on any of the alarm occurrence.Can I know whether it is due to alarm A or alarm B. when it wakes ...
Are there any examples of the Bluetooth Advertising or Broadcasting mode of the B-L475E-IOT01A?
Hello,I am currently working with the B-L475E-IOT01A board. Through bluetooth I would like to use the mode in which I send data periodically and an external device, when it enters the transmission range, can read this data.So I was wondering which of...
Bad signal when using DAC'S full range and buffer
Hi,I've been trying to synthesize different waveforms with my F446 DAC. Three things have come to my attention here, which I can't explain. First, when I am using the full range of the DAC with values from 0 to 4095 the signal gets distorted like thi...
Strange temperature dependent "software" bug with QSPI transfer
Hello,I have a strange problem... We have a bunch of equal boards (STM32H743XIH6) from manufacturer and some have temperature dependent problems (3 of 20). The problem seems like a software problem, but many software changes couldn't reproduce this.I...
STM32H743 UART RX DOES NOT RECIEVE CORRECTLY
I have two stm32 on my board. I send serial data from stm32f407 to both max232 and stm32h743. The output data from the max232 is correct. but when I debug the stm32h743 input serial data, its data is incorrect. what is the problem?
