Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I'm relatively new to STM32 and it's my first time working with DMA so this will probably be a very basic question.I'm using STM32G474 and I want to have 3 channels of advanced timer TIM8 working in "PWM generation CHx CHxN" mode. At a later stage I'...
I want to use the standalone CRC module to offload calculations AND transfers from CPU - using purely DMA memory transfers - is this possible on the STM32G474RE?
Hello @Community, I am working on the STM32F746NG board. In my application, I want to communicate with a PLC using the EtherNet/IP communication protocol to exchange real-time data. The problem I am facing is that my board does not respond to ping wh...
Hello,I need to communicate with a component whose configuration register expects a 9-bit value. However, my current SPI setup sends data in 8-bit chunks.In this case, what would be the correct approach? Should I send two bytes back-to-back? Or would...
Hi，I would like to in-live upgrade firmware of STM32F407 through USART1, that means in-application program(IAP) . If I remember right, there need a trigger signal from key meanwhile NRST is low.My question is that the Key signal could be connected t...
Hi everyone!I'm having trouble in measuring the VBAT through ADC. I'm using 3.3V on aNUCLEO_476 board to connect to VBAT and when I measure VBAT through ADC,I cannot obtain the value of the VBATHere's my code:void MX_ADC1_Init(void) { /* USER CODE...
Hello,I can run older TCP/IP examples on my F767 Nucleo but I want to start fresh and understand what is going on.Basic project started with CubeIDE/CubeMX code generation. FreeRTOS, LWIP, fixed IP => Does not answer to ping. Turns out MX_LWIP_Init()...
Hi,I’m working on an STM32F767 custom bootloader with two application slots:Main Application Slot → starts at 0x08040000Backup (Factory) Slot → starts at 0x08100000I have written a bootloader that checks both slots and jumps to the valid application...
I'm working on a STM32C071RB, which I've managed to generate PWM pulses as desired. However, I try to more than once while the chip is running, it stops working.My main.c file:#include "main.h" #define PWM_HI (12) #define PWM_LO (6) TIM_HandleType...
Hey all,For reference I am enabling the https server using NetxDuo Stack for firmware update in my device.Initially we were using Internal Flash but now we are interested in External Flash particularly SDRAM. I was able to boot the application code f...
