STM32H723 - Qspi
Hello Support, I am not able to find the QSPI config in the STMCube 1.18.1version. I have attached the snapshot. According to the EvalBord it supports QSPI. CAN you guide me here for the setup. Best Reagrds, Manikanta

STM32F103: Failed to wake up with RTC alarm from Standby mode
Hi,We have a customized board with STM32F103, it measures water level and sends the data to a server, and then enters into Standby mode for 1 minute after setting up a RTC alarm for wakeup. Occasionally, we see wakeup failures. This happens randomly,...
Resolved! STM32 Reset pin duration
Hi,We are working with the STM32G491 board and intend to drive the NRST pin using an external device. Could you please confirm the minimum low-level pulse duration on the NRST pin for it to be recognized as a valid reset by the MCU?
Resolved! STM32G0 internal temperature invalid readout
Hello,For some reason I'm unable to get valid readout of internal MCU temperature. Maybe someone have an ide why this might be happening? System is running on STM32G0B0 MCU. I init ADC over HAL generated code and enable only internal inputs (`ADC_CHA...
STM32H7 reading FLASH causes Hardfault
The chip is H743. After performing a erase operation on a page and resetting it, when I read the page again, the debug page shows that the erased page is 0xAA. As long as I read it, I will enter hardfault. Have you ever encountered a big shot,
Resolved! MCU power consumption issues
I would like to ask about the current load. I expect to use three sets of SDADC, SPI, and USART, all of which will use DMA for transfer and operate at a frequency of 11000HZ. The clock will use an external 12M crystal oscillator. I estimate from offi...
Resolved! STM32G0B1CE schematic review needed
Hi everyone,I’ve designed a schematic based on the STM32G0B1CE microcontroller. Since there’s no official development board available for this specific MCU, I used the schematic of the STM32G0B1RE Nucleo board as a reference, along with the STM32G0B1...
Resolved! STM32N6 Internal SMPS Reference Design
I've been trying to find examples of the STM32N6 using the internal SMPS however, other than trying to reverse engineer the Nucleo or Discovery boards, there doesn't seem to be much literature available showing this.Ideally (for cost and board layout...
SPI communication using DMA on the STM32H743.
SPI communication using DMA on the STM32H743.We have created a program for SPI communication using DMA, The first send/receive with HAL_SPI_TransmitReceive_DMA is successful.However, when the exact same process is executed afterwards, all received va...
STM32U031R8 Current consumption is too high
Greetings,I have acquired Nucleo-U031R8 as I was searching for ULP controllers and specification of this one was good. I am currently trying to lower current consumption as low as possible. Previously, I have used Nucleo-L073RZ where I was able to ac...
