STM32L073/Unique device ID registers/unique ID bits [95:64]

I am confused by the naming "unique ID bits" which implies that these bits are really unique from device to device.Are these bits really unique from device to device, or are the other bits (WaferNr,LotNr [0:63]) also required to build a unique id?

I am having difficulty in getting a working clock configuration for an STM32H753 chip.

the STM32H753 chip is mounted on a board with an external 12Mhz HSE crystal and 32k LSE crystal. Using the CUBE config tool I have the attached SystemClock_Config function. The function gets stuck waiting for a valid RCC_FLAG_PLLRDY signal in line 42...

How to use HAL_SPI_Receive_DMA correctly?

Posted on June 18, 2018 at 15:00Hi,How to use HAL_SPI_Receive_DMA correctly? We need to receive an ongoing data stream via spi. For that we use spi receive with dma. But if we call HAL_SPI_Receive_DMA once before the main loop the HAL_SPI_RxCpltCall...

Timer DMA Burst mode (arbitrary waveform)

Posted on September 22, 2017 at 14:25Dear all,I'm having a problem creating a arbitrary waveform using timer 1, MCU STM32L476RG. I use STM32CubeMX (4.21.0) to generate all initialization code after which I try to start a DMA transfer from memory to ...

LWIP_HTTP_SERVER_Netcomm_RTOS program for STM32f207 microcontroller is not complied using MDK-Keil tools with limited code size . Is there any solution to compile this code?

Is there a way to view content of external flash?

Hi,I have an external flash connected to STM32F722 via SPI. Is there a way to view the content of the flash? Maybe with SEGGER J-Flash program?Thanks

Issue on Comparators inputs on STM32L031xx

Hello,On a low power application, using STM32L031x, I want to monitor a 3-level signal (24V, 5V, 0V) using COMP1 and COMP2.COMP1IN+ and COMP2IN+ connected to a voltage divider with two resistors (2M-220K)COMP1IN- connected to internal VREF, so COMP...
