Resolved! STM32H743: changes in 480MHz version?
Can someone please point me at a document that identifies any changes in the STM32H743 between the original 400MHz capable version and the latest 480MHz versionThanks

Resolved! ADC Readings Effected by Capacitors?
Hello, I am new to ST boards, so please bear with me! I am trying to get a vibration reading from a beam using a piezoelectric sensor through an analog pin (ADC reading). I noticed in experiment that the timing of the piezoelectric sensor was not qu...
Bootloader code hard fault intermittently when jumping to application
I developed a bootloader firmware application last month that worked fine. I tested dozens, if not hundreds of times, on the Nucleo-F303RE board.This morning I tried using that same code with a custom STM32f301C8TX board and it hard faulted over and...
Resolved! STM32H7 Synchronous USART receiving problem with DMA
Hello, in my project I need to read an encoder that clocks out data with clock burst. For this I decided to use UART with clock generation and DMA. (I also mixed up RX from one UART to another , but this is not a problem if request happens at the sam...
NRST started to behave like an output, and it’s stuck in the high state.
Colleagues,I’ve made a custom board with STM32L082KZ. I was able to upload firmware and debug for several days. But today I can’t upload firmware, and the NRST pin is acting strangely.The setupI’m using ST-link V2 and STM32cubeIDE 1.13.0 .My entire b...
Resolved! ADC and pullup/pulldown
Hi, for a STM32F303RE I configured a pin as an ADC input. I want to use the pullup/pulldown resistors as a voltage divider for an offset voltage. I tried to switch on both in ADC mode, that did not work. Everything is fine with the pin configured as ...
Resolved! Internal temperature sensor maximum sample rate specification for the stm32l4 series?
The ADC counts returned by the internal temperature sensor appear to depend on the sampling frequency. In other words, it looks like the temperature sensor can be read too fast (with or without oversampling) to give incorrect temperature readings. ...
UART DMA and SPI DMA problems on STM32G0B0
Hi all,I have an system that reads data form an external ADC via SPI DMA, i send the StartConversion CMD and when it's done i get and IRQ so i can read the register. I also have an UART communication that polls every 2sec for the new data, I have the...
Pulses on PC13 pin of STM32F103C6T6
The LED connected to the Blue Pill board on PC13 pin blinks after power up. Just to check the pulses on that pin, probed and seeing the attached pulses. Why are these pulses generated? I haven't seen any data about this in any of the documents? I did...
Resolved! STM32G0B0 ROM Bootloader USB DFU
Hi,I have been able to use the option bytes to configure the Nucleo-G0B1RE to jump straight into the ROM bootloader on powerup and I can see the DFU on Cube Programmer, however on our target board with a G0B0 using the same user option bytes settings...
