Internal Timer of STM32F767
Hello All, I am using the Internal RTC of STM32F767 MCU. The VBAT pin is connected to an External 3.3V Coin Cell Battery At Power ON (Debug window on STM32 Cube IDE), before HAL_INIT when i see the value of RTC BKP1R Register it is 0x5432 as I intend...
STM32G431 SPI Strange Data
Hi Everbody,im trying to setup a SPI com with a DRV8301. im using de STM32G431CBU6. a have read the datasheets mutiple times not saying that i did everything correct but i dont see it anymore. i was hoping that its just a *** mistake and some can pin...
Resolved! STM32H750B-DK Debug issue with SCB_EnableDCache
Hi all. I am aware that this topic has been discussed before here: https://community.st.com/t5/stm32-mcus-products/debugger-hangs-at-scb-enabledcache/td-p/640648 and here: https://community.st.com/t5/stm32-mcus/dma-is-not-working-on-stm32h7-devices/...
Dual ADC mode single DMA configuration - How?
The STM32H7(4/5) documentation states that two of the ADCs on board can be used in dual ADC mode, so that their 16bit samples are read into the upper- and lower halfwords of a single 32bit register (ADCx_CDR), from where a single DMA can read them in...
Resolved! STM32F4 NUCLEO-F429ZI Unable to Communicate with HMI via RS232/RS485
I am facing an issue connecting the STM32F4 NUCLEO-F429ZI board to an HMI screen that uses RS232 and RS485 communication standards. The HMI can communicate successfully with my computer, but the STM32 board cannot communicate with the computer exce...
STM32H750I USART1 Baudrate differs under cold temperature
Hello ST Forum,We are using an STM32H750I in a current project. This STM communicates via the USART1 with another STM32H750V at a baud rate of 512kBaud. The clock of the STM32H7 runs via an 8MHz HSE (external quartz) at 480MHz. The clock of the USART...
stm32h503 how read multi channel value in interrupt mode
Hello evryone:at the first it is may firt project with STM32, and don't have any experince with this MCU.I have a problem, when I read (with HAL_ADC_GetValue(&hadc1)) the multi channel ADC value in interrupt mode the value is always the same. I have ...
STM32(G4) SPI, Hardware NSS with NSSP-Diabled does not work, only with NSSP-Enabled. What is the issue?
Hello,the SPI does work with NSSP(Negative Slave Select Pulse-Mode), but it does not work if I disable NSSP. As someone pointed out the SPI NSS(P) may only work if the Pulldown of that pin is enabled, but I’m not 100% sure on that one, but it seems t...
Upgrading OpenBootloader to v6.0.1 on a STM32G473CE for FDCAN usage
Hi,I am working on a project for a STM32G473CE, that is already working with the v1.0.0 of the OpenBootloader with FDCAN in order to flash the MCU.I want to upgrade the OpenBL to the latest version (v6.0.1 : https://github.com/STMicroelectronics/stm3...
