Hi I need help setting up an Infrared transmitter using an STM32F3.I know timers and have thinkered with stm32's quite a while now, but I have no clue how I'd do an Infrared transmitter. :D I'd like to control some sort of device (f.e. a projector or...

HiI have a battery powered project, where I want to turn it on with a falling edge. MCU: STM32G431RBTo save power my plan is to set the STM32 to shutdown mode.Now my Question is, how can I wake up the MCU from a falling edge?I have read the following...

HiI get a hardfault as soon as the HALL sensor (which is connected & set up using CubeMX & EXTI GPI(O)) gets an interrupt.I have debugged the code to the part where I can safely say that the hard fault only occurs when the " __HAL_TIM_SET_COUNTER(&ht...

HiI need to control some SK9822 2020 RGB LED's.I figured out that with the information on this website I can control them over SPI in transmitt only mode.The Problem I have now is, that I need to do it using Registers and can't use CubeMX for setting...

HiI am struggling with the software from the screen manufacteur Bridgetech / matrixorbital, and find the TouchGFX Software way better.That's why I want to design a GUI in a TouchGFX style and use/program my MCU with CubeMX and CubeIDEMCU: STM32f446RE...

Ok, thanks for the quick reply!I still got a few questions...1. What is the System Wake-up then, if not for waking up? I'm asking because in the documentation it literally says "WKUP pin, configurable rising or falling edge"2. How does the MCU detect...

After debugging with the Fault Analyzer of CubeIDE I got the error, it had nothing to do with the interrupt nor the timer, I was just stupid and on the first loop when the variables weren't set to a timer value there was a division by zero which caus...

Weird thing is, that if I start, get and reset the timer in the while(1) loop, everything works without an error...It's just when I put it in the EXTI Callback function, that it gets a HardFault error

That does what I want it to do, I just wanted to start the timer as soon as one of the 2 HALL sensors is triggering, but thank you for noticing :)I'll have a look at it, didn't know it existed, I'm pretty new to more than setting GPIO's :Dthank you!

How do I set up the data sending process so that it's correct for these specific RGB LED's?
