Resolved! Will STM32H743BIT6 support only OTG_HS mode?
Will STM32H743BIT6 support only OTG_HS mode? Will it support normal USB operations by disabling OTG option? If yes which pin will control that functionality?

Impedance value of the pins
Hi, 1. In order to calculate the values of pull up & pull down resistor, in which section can we find the impedance information?2. Should we use external crystal for OSC_IN & OSC_OUT pins?3. If we are using USB2.0 FS feature what is the reference?Tha...
Resolved! DFSDM decimated frequency
Hi I have a simple question about DFSDM configuration. I want to apply sinc5 with 32 samples length and therefore get 32 times decimation. Btw, I use internal ADC1/ADC2 in dual mode. STM32H725.Thus, for a given ADC frequency F I expect to get decimat...
STM32G051 - Current Control, Cycle by Cycle
Hello,I am new with STM32. We would like to do a current control exactly like on this document :https://www.st.com/resource/en/product_training/STM32G0-Analog-Comparators-COMP.pdfpage 13But we would like to use COMP1 for ZCD and COMP2 for overcurrent...
Resolved! Differences between F411RE and F767ZI SPI interfaces?
Hi,I am accessing a DRV8873s motor driver (SPI version) on two different NUCLEO boards. My usage is limited to reading data from 2 registries.I got it to work on a NUCLEO-STM32F411RE using SPI2, with the following settings:Motorola format, 8 bits, MS...
Resolved! Transaction error trying to use DMA to write to GPIO
I've been trying to set up a timer and DMA to run a synchronous parallel bus onto a GPIO. The timer works great but the DMA keeps failing with a transaction error interrupt and disables the stream. This is on an STM32F413 chip and using TIM2_CH1 as a...
STM32H7S7 XSPI Thermal Issues
Hi there, We are having some issues with our STM32H7 when the MCU is heated above approximately 55C. This leads to a fault of some form within the STM32 which prevents it from reading an external flash which the code is being run from. This memory is...
Resolved! The relationship between STM32743 SPI_DMA and D1 RAM
When using HAL_SPI_Transmit_DMA with STM32743, must the transmission data buffer and reception data buffer be placed in D1 RAM?Also, is there a way to dynamically allocate D1 RAM? Rather than declaring an array placed in section("D1"), I would like t...
STM32F101C8 Boot Loader reload?
Hello, New here. I am working with a piece of consumer electronics equipment that uses a STM32F101C8 processor. the customer was doing an update to this unit and in the middle of the update, pulled the USB plug out of his computer bricking the unit. ...
Resolved! How to unlock the Readout protection by STM32CubeProgramer through USART
I soldered a new STM32 on the board, it can enter bootloader, but it's under Readout protection(I guess I bought renovated chip), I don't know how to unlock Readout by STM32CubeProgramer, finally, I use STVP and ST-LINK V1 to connect through SWD, and...
