STM32L4R5 FMC Micron 8-bit MT29F4G08 interfacing problem

Hi , Our project is includes one of STMicroelectronics MCU in our product .We are R&D team which includes HW and Embedded SW Developers.The main component of one of our product includes MCU STM32L4R5 and NAND flash memory MT29F4G08ABAFAWP (Memory). T...

is there an extension board for the stm32f429I discovery? I t seems to me that the nucleo extension board are not compatible with such board. Thanks!!

High noise level in the analog domain on nucleo-H743zi

I discovered that Ethernet module on the nucleo-H743zi generates a lot of interference for analog domain. I thought, that if peripheral devise was not configured in the software and was not given explicit permition to run, it should stay in power do...

A Challenge for ST

https://community.st.com/s/feed/0D50X0000BiD5izThe true challenge for ST of course is to stop experimenting with "communities" and get a decent forum software.(In case ST would not get it, this post does not show up in the posts list, even if it's ta...

With STM32H745 I want to share information between the cores. For this I defined a structure in each core and linked to shared SRAM4 region. I can successfully get data with same core write-read and M4write-M7read. But face problem for M7write-M4read.

Always get '0' for M7write-M4read.

DO NOT enable SPI when SCK is high with STM32F303

I was trapped when switching chip code to STM32F303, my SPI always send more unexpected 6 zero bits before my data. diagram below shows the detail.​The problem occurs when you enable SPI while SCK is high. My SPI works in CHPA and slave mode, I haven...

On a stm32f429I discovery board, which are the voltage of the SDA and SCL pin in I2C communication? May I connect it to a I2C device with 3.3 V. Thanks.
