Help with a seemingly constant RxHeader.
I am working with a CAN bus over a STM32 Board. I don't think the hardware is important in my question. I have tried to use the HAL_FDCAN_GetRxMessage function to get a message from a device explorer where you can easily send a message via CAN.I run ...
STM32H745 Pinging
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...
FatFS and D-Cache not working together
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...
FATFS f_write error (9) when SAI/DMA is running
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...
How config I3C Target to send NACK
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,
STM32H747I-DISCO, codec outputs noise in BSP example.
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...
UART not receiving while transmitting with another
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...
memcpy() function not working
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 ...
Resolved! Problem with Ethernet ping on NUCLEO-H755ZI-Q
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...
