Everyone, How can I use cubeMX for SDcard ? I have generated for MDK but : this function doesn't work , from UM1721 User manual Developing Applications on STM32Cube with FatFs page 21. : uint32_t wbytes; /* File write counts */ uint8_t wtext[] = "text to write logical disk"; /* File write buffer */ if(FATFS_LinkDriver(&mynewdisk_Driver,… (Show more)

Hi , I'm trying to use external I2C devices in the Audio_playback_and_record project for STM32F769i-discovery.   I think the code is using the BSP to configure the GPIO's for I2C used for internal devices ( audio codec, screen etc )   I have looked at the I2C example but it sets up the GPIO's directly in main for external I2C.   I have tried to… (Show more)

I using STM32CubeMx generate code for STM32F412 USB CDC mode, but it's not work. However, I using STM32F072 MCU that it's work now. Could anyone tell me what happened?

Hi all! I'm trying to interface a STM32F7 with an 32 GB SDHC card, using the latest firmware libraries. I'm using a STM32f746G DISCO and I started from the project under STM32746G-Discovery/Appllications/FatFs/FatFs_uSD..  I wrote a simple function and I executed it in the main after linking the driver and mounting the disk, to test reliability.… (Show more)

Hi, Currently I am trying to implement muxed NOR FSMC on STM32F207ZG nucleo board, so as it is muxed data and address lines are common, I found some APIs in hal_driver( HAL_NOR_ProgramBuffer(), HAL_NOR_ReadBuffer()). these two functions are common for Muxed and demuxed configuration?? while using these APIs how controller will come to know… (Show more)

Why the big featured STM32F746 Discovery Lacks in External VBAT pins  This makes the board completely unusable for backup test and RTC time keep up   The designer had concentrated only on big features like LCD, SDRAM, FLASH and others but simply forgot about external VBAT for testing its Backup facility   Is there any other way to make the VBAT… (Show more)

In CubeMX 4.20.1 I have opened a project from a previous version. Then when I go to edit the Properties... no window comes up!  If I open another project or create a new one, the Properties... window appears as expected.   How do I fix this? I need to review and possibly change the properties!   thanks!

Hello,    I want to use DFU for update my program on the STM32L476RG. I use a personnal board. When I put BOOT0 to VCC, the Bootloader start and we can change the firmware but my system is on battery and I have no access to BOOT0 pin and RESET.    So I want to jump in bootloader directly from software for that I have search the start addresse of… (Show more)

Why does the Nucleo/Discovery onboard ST-Link clear flash memory (0x08000000 - 0x08000200) when I connect to the ST-Link USB?   I've had this happen on multiple boards, and can watch it do this from the ST-Link Utility program.

Hi community,   I'm using stm32f769i discovery, I communicate with Vacuum Transducer via the uart protocol. Once I receive the whole data send by  the vacuum Transducer  to the stm ( @253ACK9.00E+2FF ) and that I stocked in a reception buffer ,I use a variable pression to write just the bit(7,12,13) who refer to the pression value. and then… (Show more)
