Maybe it is not supposed to be used like this:Regular receive interrupt handler and using LL_USART_TransmitData8 function.Then sending a larger configuration file using HAL_UART_Transmit_DMA on demand.This leads to these flaws:1. HAL_UART_Transmit_DM...
Hello.. can anyone advise where to download the F767 Nucleo BOM list?
Does HAL_RTC_AlarmAEventCallback work if the the MCU is in shutdown ?I am using RTC wake-up timer for wake/shutdown cyclingRTC alarm for shutdown trigger via HAL_RTC_AlarmAEventCallbackBut:RTC Alarm A interrupt never fires if the MCU is in Shutdown m...
In my STM32G431CBU6 implementation, COMP1, COMP2 and COMP3 are configured for back-EMF zero-crossing detection with TIM1 CH5 serving as the blanking source. Both rising and falling edge interrupts are enabled on the comparators. TIM1 channels 1...
According to AN5054, to prepare SFI (secure internal firmware install) or SFIx (secure external firmware install) "STM32 Trusted Package Creator" is required. Were do I find it? Searching ST website I find no such software product. Was it maybe recen...
Hi,I originally planned to program my STM32G030K6T6 via USB using the DFU bootloader, but the datasheet doesn’t mention USB_DM/USB_DP, and STM32CubeIDE’s .ioc file shows no USB option under Connectivity, so I believe USB DFU isn’t supported. What’s t...
Hi,I'm using the Zephyr platform with the STM32U5G9ZJ-DK2 board. I want to put the device into a low-power mode when it's not working. After modifying the DTS file and enabling power management, the device can enter and wake up from Stop3 mode normal...
There is an inconsistency in the Reference Manual.The Reference Manual specifies on page 917 that:"Option 2) has the advantage of using the system without additional PLL. In addition, whenadc_sclk is twice faster than the adc_hclk clock, the latency ...
Hi there Is there any stm32 MCU versions that has can run both CAN and USB simultaneously without conflicting with the PB8 boot pin? Also the USB will only be recognized if the PB8 pin is pulled high can i just directly connect it to 3.3v and always ...
Hi, I am new to the field of ST Microcontrollers and am currently working on developing firmware for a product that utilizes the STM32 Microcontroller, specifically the NUCLEO-H7A3ZI board. We are using the design implemented on this board as a refer...
