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.
Hi I encountered problem while working on project. I am trying to establish connection between devices using RS485 interface. Slave device has been designed to control servo motors, positions to be set are sent from the master. Everything worked fine...
Hello,I am having trouble in getting PC14 and PC15 working as GPIOs on the STM32F401. The reference manual says that "The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general-purpose PC14 and PC15 I/Os, respectively, when the LSE oscilla...
I've been working with an STM32CubeIDE project based primarily off STM32CubeU5 MCU package v1.4.0 (Projects\STM32U575I-EV\Examples\DCMI\DCMI_ContinousCap_EmbeddedSynchMode). The main changes I've made is changing the image format to JPEG and playing ...
hi, Can anyone please help me in USB-HID-Barcode Scanner connection with stm32f722ze. Normally Barcode Scanner will behave like keyboard and how to decode the ASCII code using usbh_hid_key.c . Request : if anyone can suggest me small example of u...
