The DBATTEN setting in the UCPD_CR register claims the following But as far as I know, the dead battery functionality is always present. It would have to be to work unless this is stored in NVM.Maybe this DBATTEN is some other Rd value? Maybe the ANA...
What is the maximum current that the STM32 GPIO can withstand when set to open-drain mode and the NMOS is on without getting damaged?
Hi, Is there an option to program the STM32L412RB with DFU / Serial interface? I was programming the STM32F407 with DFU and Serial before and now I want to use the STM32L412RB and program it the same way. I can't find any information on the BOOT1 pin...
Greetings, I am having trouble in waking up from Stop mode in STM32U585RIT6 LQFP64 MCU. So I saw the following posts: https://community.st.com/t5/stm32-mcus/troubleshooting-waking-up-from-stop-mode-issues-with-lptim-in/ta-p/745343https://community.st...
Following this post describing how to disable speculative accesses on external memories range (0x6000 0000 to 0xDFFF FFFF) on Cortex®-M7 processors, I'm wondering if such mechanism should be done to:- memory regions marked as reserved:Source - DTCM /...
Hello, I am trying to implement an edge AI application on the B-U585I-IOT02A board alternating between active mode for inference and stop2 mode. I based the implementation on the PWR_LPMODE_RTC example for the U575 board, I have attached main.c below...
I am developing libraries for STM32G070RB and starting with DMAs TX and RX; the interrupts trigger for both modes. I am using STM32G070RB, Cube IDE (1.19.0)Description of task:I wish to make the library optional for the user.1. Option DMA (TX & RX) h...
My company is developing a system that needs to download thousands of images from a computer to an STM32 development board via a local area network. The total size of the images may reach tens of GB (if possible, the data should remain even in the ev...
Hi,I'm configuring the independent watchdog in the STM32F103xx medium-density using the registers.During the IWDG the PVU bit is not cleared by the hardware. The reference manual (page 498) says the following:"PVU: Watchdog prescaler value updateThi...
I am unable to start a PWM signal on my Nucleo board --> I was not able to observe a signal on an oscilloscope.Please see the following code and Cube configurations.1) Is the following code all that is necessary to start a PWM on a channel (given it ...
