Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
On the STM32F042G6U6 the USB DP and DM lines have to be MUXed onto pins 19 and 20 by way of the PA11_ PA12_ RMP bit in the SYSCFG_CFGR1 register.I would like to use the USB DFU mode of the device. So will the USB DFU work (i.e MUX the DP and DM lines...
The CubeMX HAL library is considered and claimed to be "thread safe". One can select FreeRTOS on the CubeMX and generate a code.I am questioning whether the HAL is indeed 100% safe for using with RTOS. The HAL allows read/write to specific bits in th...
Hy,as described and discussed earlier (https://community.st.com/s/question/0D50X00009sWdDqSAK/stm32f042-bootloader-activation) I want to use bootloader mode of STM32F042 to update STM32 firmware in a multi CPU system. I still see this way as very ele...
I'm very new to the STM32, so sorry if this sounds stupid. As far as I could understand looking at the datasheets, the STM32F407XX has 2 DACs, but when embedded in the discovery board an external DAC (CS43L22) is used. Why is that?
I'm using a STM32F429ZI Nucleo-144, and need a counter/delay function with 1 microsecond resolution, but want to keep the HAL_Delay function at 1 millisecond resolution for other uses.I'm looking at potentially reconfiguring the SysTick interrupt to ...
Posted on June 02, 2017 at 21:28I have a STM32F746NG Discovery board on which I have implemented a USB Composite device with MSC and custom HID classes. I also want to run Elm-Chan's FATFS to read and write files locally on the micro-SD card whilst ...

Hlello. I want to use single wire and half-duplex mode for spi master.Init works, and HAL_SPI_Transmit function works .But it will go to timeout when call HAL_SPI_Receive function from HALL. it still can't get RXNE FLAG . I measured it , it didn't g...
Posted on June 01, 2017 at 17:34Hello, I have some problems to implement a bootloader in a STM32F4. I searched on internet and I found coherent informations and examples, but I 'm not able to make simple test work.Here my simple code:bootloader (wri...
Hi,in order to reset my I2C sensor TLE493D-W2B6 A0 I need to send 4 bytes which consist of 0xFF->0xFF->0x00->0x00 . So no address or anything else, only the 4 bytes transmitted with 4 consecutive I2C accesses.Now I am using a slightly modified versio...
