Hi, may i know how to use the uart using stm32h750. I just try using the basic uart application which is hello world but nothing show up. I literally follow same setting with nucleo board for uart. but it does not working with stm32h750? May i know i...
I am working on a project where several STM32L0xx processors will be running under a Raspberry Pi 4+ system. The desire is to be able to use the SystemBootloader on these to be able to do firmware updates. I know that the documentation from ST is eno...
I want to be able to run a bat file that has inside it the path to a hex file. When i run it, it converts it to a dfu file, without the user needing to do any more clicks or inputs. I tried to do this by using encedo's hex2dfu from github. The proble...
Hello,Reading the datasheet, pads PA11 and PA12 can be remapped to PA9/PA10.I don't understand how this remapping works.Variant A-------------This is a full swap, meaning that pads PA9/10 will exchange with PA11/12 ?Variant B-------------Pads PA11/12...

Hello guys, I have a problem with my project. I'm development the PS/2 (device, keyboard-like) protocol with my STM32F103C8T6 (Bluepill). When i convert my port to the open collector output, the noise appear in the PS/2 bus. In this moment, the STM32...
Hi, Im trying to get WUP reason after the MCU exited the shutdown. I'm using pushbutton connected to PC5 pin to wake up the MCU. I cannot get the WUP flag to behave correctly. Sometimes it is present, sometimes not. This feature is part of bigger pro...
Hi,on STM32H7 I want to divide 25600/1000 - I get always result = 25. Why? What I do wrong?double freq; int odr=25600; freq = (double) (odr)/1000;Thank you
I am trying to simply turn PA0 HI on an STM32F030F4P6 using Cube IDE.No matter what I do, if I try to write to any GPIO registers (including using the auto generated Inits), I get a Hard Fault. Nothing solves it :( Tried debugging it, no matter what...
