Hi,i know the gotcha about the late clearing. My interrupt (yes it currently useless) is so short, that clearing in the beginning would not work either, so i tried to implement a check for the interrupt flag. But with no success: It is fired twice.Is...
In order to mute the COMP for some time, I deactivated the interrupt with HAL_NVIC_DisableInterrupt(COMP_IRQn) and re-activated after a certain time respectively.In between I am in STOP2, some uA normal consumption.Now, while the interrupt is disable...
I'm trying to understand the following excerpts from the STM32L476 datasheet, which seem to contradict:In Table 20 - the absolute maximum voltage on the VREF+ pin is given as 4.0V (VREF+ I assume falls under the "other" category). Table 76 seems to i...
Hello,This is the first time I've designed a PCB with a stm32. I found a PDF on the internet that gives me an example of a Nucleo connection but I'm not sure if my schematic is correct.I don't need all the headerts or the usb connection (I'll be usin...
Hi all, I am running into an issue related to writing backup registers on the STM32U535xx MCU. When I compile my code with -Oz, the write fails, whereas with -Os, it succeeds. The relevant C code is pretty straightforward:LL_PWR_EnableBkUpAccess();LL...
Hello everyoneIs it possible to program my STM32F745 via RS-485 using the integrated bootloader?My idea is using USART1 (as written in the AN2606) and a transceiver to do that. Has anyone done something similar? Thank you very much in advanced. Best ...

Dear team,Please assist in providing the latest RMI_CMRT_6.31&RMI_EMRT_1.2 for STM32 MCU series, thank you.
Used this ST-Link V2 with W10 some years ago. Now on Linux I want to use it with openocd and got error:ST-Link version does not support DAP direct transportMost likely the cable adapter needs update.But the STLinkUpgrade.jar reported Unexpected flas...
Hi,I'm currently debugging what I think to be a code issue. I have a custom board with all peripherals physically disconnected and a NUCLEO-U575ZI-Q dev kit. The lowest current I see is about 250uA on both setups, with a sawtooth charge/discharge wav...
