I am trying to write my own I2C driver but I have been having an issue that after sending the start condition both SCL and SDA lines go low and stay that way. After some painful debugging I realize that the I2C event interrupt handler is not being ca...
Hello,I am trying to use this code to save a 332 byte (83 double word) long data to the STM32L496 flash memory. For some unknown reason, every second time I call the function, I encounter a PGAERR. The third time it works fine, but the fourth time it...
Hello Forum Members,I need a project for a HTTP Client functionality for STM32F767ZI Nucleo board using NetX Duo or a reference. Please guide me on the same.I could make the default example for TCP client from ST Microelectronics. But not sure how ca...
These's a very strange bug in current verion of STM32G4 HAL library(STM32Cube_FW_G4_V1.6.1) and it took me 2 days to find a workaround.The problem is:When normal power on, everything is fine.When compiler optimization set to -o1, everything is fine.B...
I want to transfer a buffer and receive a buffer of data using a full duplex SPI port with DMA on a STM32H7S3L8H (on the NUCLEO-H7S3L8). My problem is I am not able to modify the transfer buffer and have the modified version sent. I only need to modi...
I am trying to implement an IWDG in my program, which will save the value of the specified register to EEPROM before resetting. The STM32 I'm using is STM32H563. But I found that my program is not working (cannot save data to EEPROM before resetting)...
I have a NUCLEO-C092RC board. When I connect to a terminal and start the board I get: Demo mode launchtest sw version SW V-0.2.0- Loopback L1(L) -> L3 ==> FAILEDI have looked around and haven't found what the 'failure' is. I would also like to see ...
Hi,Context : STM32F777, FreeRTOS, Cmsis V2, LWIP, Sockets, TCP, UDPOnly one task is used to open, listen, poll, accept, send, receive, and close sockets. Since STM32CubeIDE 1.7.0 and the new version of ethernetif.c, modifying "low_level_output", we h...
Hi, I had to recently work on an application that makes use of the UART, and encountered some issues in the HAL (most recent version provided by CubeMX):1) Hal bug?Drivers/STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_uart.c, Line 3825:3831if (!(IS_LPUART_I...
Hi,I'm having an issue implementing USB device composite functionality on my Nucleo-H753ZI board. I've been following the tutorial series at https://community.st.com/t5/stm32-mcus/how-to-implement-the-usb-device-composite-class-in-stm32-using/ta-p/64...
