Hi, I'm using STM32L0 MCU, My system uses MSI as the main system clock, but my USART is to use HSI to be able to wake up from stop mode. My system will enter stop mode for power saving. I am confused about the settings, before enter stop mode, we ha...
Hello, I'm working with a STM32G0B0CE part. I believe that the TRM definitions for RCC_CCIPR2->USBSEL are incorrect.I was having trouble with USB, seemingly related to clock selection. I noticed in the LL HAL headers the following:#define LL_RCC_US...
I am developing software on the Nucleo-L433RC-P board but have a strange situation when debugging.The first time I debug, the software does not run and I get the following error... Break at address "0x1fff2ce8" with no debug information available, or...
Dear,i used STM32F205RB MCU, could you tell me:1.why the MCU can not wakeup?2.how can i solve it? tin tai
I'm using the AWD (STM32G0B0CE) with the HAL_ADC_LevelOutOfWindowCallback(), which works fine.For not blocking the MCU completely, I'm disabeling the AWD-IT inside the Callback when fired for about 500ms:LL_ADC_DisableIT_AWD1 (ADC1);After the 500ms e...
I have received some STM32F405RGT6 microcontrollers that have two circular marks (holes) on the package, while the official datasheet only shows one mark indicating pin 1.Is there an official revision or packaging variant from STMicroelectronics that...
Peripheral: QSPIBug: Bit 4 of FTHRES[4:0] in the Control Register is not set when written with threshold values in the range0x10 - 0x1F. Works fine for threshold values in the range 0x00 - 0x0F. So, for example, if one writes 0x16 for athreshold leve...
Hi,I need to run my application in the external flash, as the size of the internal flash is very less for the stm32h7s78-dk board. I have turned on optimizations as well, but i need external flash configuration. probably XSPI1, XSPI2 what all the thi...
Hello,I'm working on a firmware which currently run in USB vendor interface (bInterfaceClass = 0xFF) and it's working.Now I want to add MassStorage. My Firmware is a bit older so I add all usb composite parte by my self (in usbd_core ...) . I defined...
I am facing a strange issue that looks like a possible microcontroller design/behavior problem.My setup:I need the DAC output pin to provide a stable voltage while the microcontroller is in STOP2 sleep mode with the RTC running.Power connections: Vb...
