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...
Hello,We would like to program new STM32H7 chips (running the default bootloader) from another STM32H7 over UART. Looking at AN3156 and AN2606 this seems to be possible but is there any sample projects or drivers (by ST or open source) that implement...
Hi guys,I'm currently trying to figure out how to flash a new software update on a Discovery kit STM32 B-L4S5I-IOT01A (dual flash bank) via Azure IoT Device Update. I've followed Microsoft's example on Github (link) and it works. What I have trouble ...
Hello,I made with cubemx an ethernet project for the stm32f439 (custom Board), but it doesn't works. When i just use the stm32f407 Discovery Board with the same project, it works without any change. The custom board has the same DP83848 Phy. I read t...
Hello,I am using STM32H7 dual core series. My STM32CubeIDE works fine when I am using HSI. But whenever I set the configuration to HSE, I am getting Break at address "0xa05f0000" with no debug information available, or outside of program code error. ...
I want to share my related code and photo here. The program runs on an STM32F746 Nucleo Board. It uses timer 2 to trigger DMA1 stream 0 causing fixed-length transmission of data via SPI 1 to an external ADC without interrupts on the transmission sid...
Hi All,I'm facing a strange issue on UART, I generate the code by CubeMx for UART functionality, UART is working fine but when ever i remove the TTL (Serial to USB) and keep Rx pin float, UART interrupt occurred continuously and main application stop...
Hi all,I am trying to generate a PWM signal with both variable pulse width and period. I think the HAL_TIM_Base_Start_DMA function can only generate it with variable pulse width but not variable period. I have checked the timer cookbook and found the...
Bonjour, J'essaie de faire communiquer ma carte Nucleo-723ZG avec un périphérique LIN.Apriori, ma carte est adapter au protocole LIN et j'arrive à configurer mon périphérique USART1 en LIN. J'utilise avec ma carte un transceiver LIN. Quand j'envoi un...
MCU is STM32L4R9 with 1MB. I'm having trouble getting the device to erase the upper half of the flash programmatically. Apparently the device ships with opt bytes set for dual bank.I connected the device to the STM32 programmer through USB and turn...
Hello,I am working on stm32u585 (B-U585I-IOT02A) board with BG95 M3 as cellular modem, I have intergrated x-cube-cellular package with freeRTOS for cellular modem.Now I am creating task that connect with Azure IoT hub for that I have integrated azure...
