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...
Hello everyone, I am trying to establish a connection between my STM32H745I(Discovery kit) and my computer and the jumpers are set to STLK for programming, and I also have connected the board through LAN to my computer directly. I have set my compu...
Issue with FatFs and D-Cache on STM32 (CubeMX Library)I'm having issues using FatFs with D-Cache enabled on an STM32. After searching, I found several posts reporting similar problems, but I haven't seen a clear solution.I’m using the FatFs library t...
Hello, I am trying to record audio data from an ADC to a SD card with a nucleo STM32L552ZET6QU board. To write data into SD card using FatFs I initialised it : "// Open the file system - mount the drivefres = f_mount(&FatFs, "", 1); // 1 = mount now...
Hi, I would like to know how to disable address acknowledgment in I3C when operating as a target (with an already assigned address) to temporarily hold communication, similar to the OA1EN bit in I2C.Thanks,
Hello,I built and uploaded the BSP example from the H7 MCU package, version 1.12.1, on my STM32H747I-DISCO board. I tried the various demos included in the example and they work but it seems there is an issue with the codec configuration.(I didn't ch...
Hello, I am using STM32F407 Transmitting some data over UART and Receiving the same data with another in INT on the MCU.The problem is that the receiving side gets only the first byte even when switching sides the receiving side still receives only t...
Hi,I'm using the STM Cube IDE version 1.15.1 along with NucleoG474RE board. My C application requires the use of memcpy(). The memcpy() function should copy the values from an unsigned char source buffer to the unsigned char destination buffer. This ...
Hello,I'm trying to get an Ethernet ping with NUCLEO-H755ZI-Q to check if everything works. To eliminate any possible errors from my side, and since there are no ready projects for H755, I'm using this project that I've found in this post. I have:ope...
I've already contacted support, so this post is just for community.There's a bug in HAL_SetTickFreq function (stm32f4xx_hal.c)---8<---HAL_StatusTypeDef HAL_SetTickFreq(HAL_TickFreqTypeDef Freq){ HAL_StatusTypeDef status = HAL_OK; assert_param(IS_TICK...
Dear ST I have some question about i2c read functions Currently we use zephyr os (version 3.4.0) the stm32f412RGT used as the host and the host reads a 5-byte value from another mcu used as a slave throughi2c the following problem occurs once every ...
