Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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 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...
Hi,On a STM32 F7, I would like to lock access to the FLASH_CR by writing a wrong key to the FLASH_KEYR register. Writing a wrong key results in a bus fault (disabling the bus fault raises it to a hard fault).Could someone help me with a way to write ...
Hello,I am developing a USB PD sink application on custom board with STM32G0B1VETI am using periphery UCPD2. I followed AN5418 to set up eveyrthing in CubeMX and add the specified pieces of code.Hovewer, ithe USBPD stack doesn't seem to send or recie...
Starting from this video (https://www.youtube.com/watch?v=CGUC1wqSLCE) I'm trying to write my bootloader for DFU from an USB stick. The code works but I would like to tweak it such that:if at boot an USB stick is detected, than start the update, othe...
Hi everybody,Is there a commonly used or already-built system for platform/chip abstraction between multiple STM32 parts? I have encountered various PAL's over time, some better than others, but I was curious if there is one common one that people us...
