quad-spi over an octal-spi on an STM32H723XX
Is there a working sample code that interface quad-spi over an octal-spi on an STM32H723XX mcu?Has anyone tested such a scenario?

Default struct fields alignment
Hello,which is the default struct fields alignment policy of GCC, on STM32 MCU? I have the following structure: typedef struct{ uint32_t param1; float param2; uint16_t param3;} PARAM_T; I expected a size of 10 bytes, but it is 12 instead...
OSPI in QSPI mode, issue with sending address
I'm importing some QSPI code we've been using a few years from an SMT32F7xx project to a new project using an STM32L4xx. Both projects use the same target device. I'm having an issue where the majority of messages don't seem to be sent. After debuggi...
Resolved! I can't connect my Nucleo to my STM32L0 board
Well, I'm new to the STM32. I'm developing vibration and temperature sensors, which used to be equipped with an atmega.With the new demand for processing I decided to upgrade by putting an STM32L0 in place of the old controller.The problem is that no...

Hi ST-CommunityI am working on CAN Communication in F103When I am de-initializing properly , But when , I am reinitializing it is not workingPlease tell me how to reinitialize CAN Communication if (0 == HAL_GPIO_ReadPin(BRAKE_GPIO_Port, BRAKE_Pin)) {...
Resolved! Zephyr: how DAC on STM32H723ZG ?
Dear all,does anyone have experience with setting analog output signals via Zephyr RTOS? I managed to get the D/A conversion on the Nucleo H723ZG to run via STM32CubeIDE, but I’m running intro trouble when using Zephyr. Apparently a "DAC" driver is r...
Update firmware from W25Qxx flash
I use a board with STM32F405 + W25Qxx. At the moment, I have implemented downloading the firmware file to an external flash memory (via CAN). The process of downloading and verification is implemented in the main firmware. It is necessary to implemen...
Correction Request: Internal RC Oscillator accuracy specs For STM32F4 (possibly others)
Please see this thread from 2018 https://community.st.com/t5/stm32-mcus-products/stm32f4-hsi-accuracy-drift/td-p/360021 The poster complains that the datasheet claims 1% accuracy for the RC oscillator over full temperature range, but other sources (s...
