Hello I'm developing RTOS environment of dual-core in STM32H757.I could refer to the examples provided by STM32, and I read the application note AN5617. I checked that the error is a exception "err1" under the function "rproc_virtio_create_vdev" in ...
I am currently trying to figure out at what byte the slave sends a NACK during an I2C master write transfer.When the slave sends the NACK after X bytes the error callback is called. Inside the error callback I am having trouble finding out at what by...
HiI am am trying to use the X-CUBE-EEPROM package in my application.I found this very helpful post which I am using as a guide to setup the code.https://community.st.com/t5/stm32-mcus/porting-and-using-x-cube-eeprom-with-any-stm32/ta-p/570539I think ...
Hi,I am creating a project using the STM32H523 microcontroller. One of the planned functionalities is USB CDC communication with a computer (as a virtual COM port device). Since I do not plan to use RTOS, I would like to use the classic USB library.I...
Posted on January 20, 2015 at 02:55 Hi I have the camera demo for STM32F4Discovery working which can display the image from camera (OV9655) to the LCD (DM-LCD35RT). I also have fatfs for SDIO working. I am writing the image data to a .bmp file o...
Hi community,like the title says, I need your suggestions regarding firmware update via UART on an STM32F446RET6.So I developed a product with the STM32F446RET6 chip. The only accessible protocol to my users is UART1, on which I implemented Modbus RT...
Hello,I am currently working with the STM32H7S78-DK board, using STM32CubeIDE for programming. My goal is to configure the Ethernet peripheral and send/receive data via UDP. As a reference, I am following the example project provided at the following...
Hii, I have been trying to interface Nucleo-H503 with SD card adapter which has SPI pins to interface, in stm32cubeide i selected SPI1 and FileX in the middleware. But unable to get how to write code for it for creating file and saving Helloworld in ...
Hi All,I've been having issues with unreliable SPI transmission on an NUCLEO-H753ZI using ST H7 HAL HAL_SPI_TransmitReceive() talking to an ICM-42688-P IMU over SPI1 at 1 to 12 MHz clocks, with H753ZI RCC set up at 400MHz CPU clock and a 25 MHz SPI1,...
Hi, I am building a custom board with stm32h7r3z8t6. Have a problem with EXTI function: I use 2 EXTIs - EXTI8 in PD8 and EXTI9 on PC8. Both are defined as rising edge interrupt sources. Both pulled down and without any signal. Both are toggling LEDs...
