Hello, Community.I am currently trying to control a power converter with a STM32F4 microcontroller. The thing is that the control variable is the frequency of the PWM. I have programmed a timer (TIM3) that generates an interruption every 100us. Durin...
Dear community I am new STM32G4 family bu i have several years of experience with C2000 form competitor TI. I would like to use STM32G4 controller in new project but i have lots of problems. I have read AN4539 HRTIM cookbook and HRTIM chapter in Refe...
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 there,recently I have found an error in the reference manual RM0410.On page 1546 in figure 503 Filtering mechanism - example it is Identifier #4, which matches the recevied message. However, in the description below it said Identifier #2. I don...
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...
