STM32 MCUs Products

STM32F103C8T6 Sometimes it's good and sometimes it's bad

After normal power-on, the MCU does not run, but as long as something is used to shield it, it will return to normal. Help to see what is the reaso

STM32H735G-DK: Is unaligned HyperRAM memory access possible in memory mapped mode?

Hallo,we are using STM32H735G-DK boards and wondering whether unaligned access of memory mapped HyperRAM should be generally possible or not.In the errate sheet for the STM32H735https://www.st.com/resource/en/errata_sheet/es0491-stm32h72xx73xx-device...

STM32H745 DISCO line in audio

I have wrote software for recording audio from line in to wav file for STM32H745 discovery board.But output file is distortion (original file and output file is in attachment) Input file and output file is the same sample rate (32khz, 16 bit, 2 chann...

STM32H743 does not set EOT-Bit when SCK is to high

Hello STM community,I am currently trying to get my Nucleo STM32H743ZI2 to send data via SPI to a different chip.Im using CubeMX to generate a lot of the setup code as I´m pretty new to this chip. For the same reason, I use the HAL.The basic configur...

Example of OpenAMP send message from core M4 to M7 (Nucleo H745ZI)

Hello everyone,I am using Nucleo H745ZI dual core and I want to communicate intercore by OpenAMP.The ST only giving example send message from core M7 to M4. But I want to send message from core M4 to M7, I tried follow the OpenAMP flowchart but not w...

Resolved! STM32G030F6P6 TSSOP20 crystal oscillator?

As I understand, the TSSOP20 version needs an external oscillator instead of a 8MHz crystal connected directly to the MCU pins. Is that correct?I'm asking because I have seen a board on AliExpress using this same processor with a 8MHz crystal.

USB_OTG_HS and USBX (host only, MSC) doesn't detect connection.

I have a U599 embedded display board, that has a dedicated software pack for TouchGFX.I was able to configure most peripherals on the board, including SD card and FILEX that required THREADX.So far so good, so I activated USB_OTG_HS and USBX. I have ...
