Hi, I have a development board with an STM32H745XIH6 microcontroller, which has dual cores. I am trying to debug using the SWDIO and SWCLK pins. Debugging works fine on the M7 core, but it does not work properly on the M4 core. This is what the issue...
Hi,I have developed an application using the STM32F103C8T6 MCU to function as a USB keyboard. The application uses the USB communication protocol to send keystrokes. One of the requirements is an emergency button that, when pressed, disables all othe...
I am a beginner. Please help me figure out why the interrupt is not happening. I want to measure the duty cycle, but the interrupt is not enabled. I am losing hope that this is possible.#include <stdint.h> #include <stm32f0xx.h> #include <stdbool.h> ...
Hello everyone,I'm using Netconn snmp over freertos on my project and I found an issue when using 2 netif interfaces. The problem is that when I receive udp messages, the response is always routed to the default netif despite having the LWIP_HOOK_IP4...
i am looking for the equivalent function ofextern frac16_t GFLIB_Atan_F16_FAsm(frac16_t f16Val, const GFLIB_ATAN_T_F32 *psParam); from nxp mlib.h in a stm32 library
When starting uC (or performing a reset) with the cable connected to the router, ping.exe receives a response normally. If the cable is removed, ping.exe does not receive a response, but after reconnecting, ping.exe receives a response.The problem is...
Hi, I am currently working on a project for the STM32H523 microcontroller. In the project I want to use AZURE RTOS to support a pendrive connected to the USB port. I know that I have to use the THREADX, USBX (host mode) and FILEX packages. Unfortunat...
Hello, everyone,I'm using a STM32L431CC and I'm having a hard time making an OTA firmware upgrade while my device has the RDP level set to 1.I've configured my Option Bytes on my bootloader and it appears to work correctly: the application code runs ...
Subject: SD Card Communication Issue in 4-bit Mode Iam using STM32F756ZG micro-controller.I am currently working on interfacing an SD card and have noticed an issue when switching between communication modes. The code executes as expected in 1-bit mo...
GreetingsI am trying to use 2 UART interfaces on the STM32L4xx series and echo what's received on 1 interface. I am receiving strings of unknown length on UART1 using the DMA and echo-ing it with the virtual com port (UART2). I intend on using receiv...
