Hi, I am trying to send an integer from the PC (using Putty serial program) to the Nucleo board via USART interrupt but the board doesn't acquire the number correctly. In the code written here this happens: if I send any kind of number to the board l...
Is there any update on this issue? I have similar problem with being not able to initialize SD Card using SDMMC1 + FileX + ThreadX. Getting SDMMC_FLAG_CTIMEOUT while initialization (SD_PowerON() function). Does someone have maybe a working example of...
Hello everyone.I configured stm32H733VGT6 to support the usb2514 hub device. To do this I used Azure RTOS and the USBX library with STM32CubeIDE Version: 1.17.0. Everything works fine, the USB2514 device is always recognized at power-on with the corr...
Hello.I am using USBX pima_mtp device class.The project uses the example from @example with some changes:Storage type was changed to ierarchical.Added support for image type associations.MTP functions were implemented in ux_device_pima_mtp.c Each obj...
Good dayI am using a NUCLEO-STMG0B1RE board and i am trying to handle a 4x3 matrix keypad inputs using interrupts to switch menus on an OLED screen. The keypad inputs worked when I used continuous polling for keypad inputs. The OLED needs to continuo...
i need to develop a custom HID device, where I can be able to control the LEDS using HID. the user can control using PYTHON OR GUI please provide me the code i am using NUCLEO-H723ZG
I want to connect my STM32H573I-DK to Azure IoT Hub via MQTT over websocket to avoid firewall complications.For that I am using STM32CubeExpansion_Cloud_AZURE_H5_V1.1.0 project (https://www.st.com/en/embedded-software/x-cube-azure-h5.html). I added N...
Hi, I am curious one thing when using the HAL libraries. Just as an basic exapmle i assign LED1 to PB12 pin of STM32F070CBT6 as an GPIO_output. And i want to use HAL_GPIO_WritePin(GPIOB, LED1, LED1_SET); instead of HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1...
Hi everyone,I'm new to embedded programming and trying to understand how SVC (Supervisor Call) works on ARM Cortex-M.I wrote a small program that triggers an SVC call, and in the SVC handler, I try to extract the SVC number by accessing the PC that w...
We are experiencing issues when using system bootloader on STM32H7 MCUs. Enter to the bootloader is correct - when BOOT0 pin is held high and reset is performed, MCU enters system bootloader. We use USB DFU for communication with bootloader and PC ca...
